NAME
fzf - a command-line fuzzy finder

SYNOPSIS
fzf [options]

DESCRIPTION
fzf is a general-purpose command-line fuzzy finder.

OPTIONS

  Search mode

-x, --extended
    Extended-search mode. Since 0.10.9, this is enabled by default. You can disable it with +x or --no-extended.

-e, --exact
    Enable exact-match

-i  Case-insensitive match (default: smart-case match)

+i  Case-sensitive match

--literal
    Do not normalize latin script letters for matching.

--scheme=SCHEME
    Choose scoring scheme tailored for different types of input.
    default Generic scoring scheme designed to work well with any type of input
    path Scoring scheme well suited for file paths
    history Scoring scheme well suited for command history or any input where chronological ordering is important
             Sets --tiebreak=index as well.

--algo=TYPE
    Fuzzy matching algorithm (default: v2)
    v2 Optimal scoring algorithm (quality)
    v1 Faster but not guaranteed to find the optimal result (performance)

-n, --nth=N[,..]
    Comma-separated list of field index expressions for limiting search scope. See FIELD INDEX EXPRESSION for the details.

--with-nth=N[,..]
    Transform the presentation of each line using field index expressions

-d, --delimiter=STR
    Field delimiter regex for --nth and --with-nth (default: AWK-style)

--disabled
    Do not perform search. With this option, fzf becomes a simple selector interface rather than a "fuzzy finder". You can later enable the search using enable-search or toggle-search action.

  Search result

+s, --no-sort
    Do not sort the result

--track
    Make fzf track the current selection when the result list is updated. This can be useful when browsing logs using fzf with sorting disabled. It is not recommended to use this option with --tac as the resulting behavior can be confusing. Also, consider using track action instead of this option.
    e.g.
         git log --oneline --graph --color=always | nl |
             fzf --ansi --track --no-sort --layout=reverse-list

--tac
    Reverse the order of the input
    e.g.
         history | fzf --tac --no-sort

--tiebreak=CRI[,..]
    Comma-separated list of sort criteria to apply when the scores are tied.
    length Prefers line with shorter length
    chunk Prefers line with shorter matched chunk (delimited by whitespaces)
    begin Prefers line with matched substring closer to the beginning
    end Prefers line with matched substring closer to the end
    index Prefers line that appeared earlier in the input stream
    - Each criterion should appear only once in the list
    - index is only allowed at the end of the list
    - index is implicitly appended to the list when not specified
    - Default is length (or equivalently length,index)
    - If end is found in the list, fzf will scan each line backwards

  Interface

-m, --multi
    Enable multi-select with tab/shift-tab. It optionally takes an integer argument which denotes the maximum number of items that can be selected.

+m, --no-multi
    Disable multi-select

--no-mouse
    Disable mouse

--bind=KEYBINDS
    Comma-separated list of custom key bindings. See KEY/EVENT BINDINGS for the details.

--cycle
    Enable cyclic scroll

--keep-right
    Keep the right end of the line visible when it's too long. Effective only when the query string is empty.

--scroll-off=LINES
    Number of screen lines to keep above or below when scrolling to the top or to the bottom (default: 0).

--no-hscroll
    Disable horizontal scroll

--hscroll-off=COLS
    Number of screen columns to keep to the right of the highlighted substring (default: 10). Setting it to a large value will cause the text to be positioned on the center of the screen.

--filepath-word
    Make word-wise movements and actions respect path separators. The following actions are affected: backward-kill-word
    backward-word
    forward-word
    kill-word

--jump-labels=CHARS
    Label characters for jump and jump-accept

  Layout

--height=[~]HEIGHT[%]
    Display fzf window below the cursor with the given height instead of using the full screen. If a negative value is specified, the height is calculated as the terminal height minus the given value.
      fzf --height=-1 When prefixed with ~, fzf will automatically determine the height in the range according to the input size. Note that adaptive height is not compatible with top/bottom margin and padding given in percent size. It is also not compatible with a negative height value.
      # Will not take up 100% of the screen
      seq 5 | fzf --height=~100%

--min-height=HEIGHT
    Minimum height when --height is given in percent (default: 10). Ignored when --height is not specified.

--layout=LAYOUT
    Choose the layout (default: default)
    default Display from the bottom of the screen
    reverse Display from the top of the screen
    reverse-list Display from the top of the screen, prompt at the bottom

--reverse
    A synonym for --layout=reverse

--border[=BORDER_OPT]
    Draw border around the finder
    rounded Border with rounded corners (default)
    sharp Border with sharp corners
    bold Border with bold lines
    double Border with double lines
    block Border using block elements; suitable when using different background colors
    thinblock Border using legacy computing symbols; may not be displayed on some terminals
    horizontal Horizontal lines above and below the finder
    vertical Vertical lines on each side of the finder
    top (up)
    bottom (down)
    left
    right
    none
    If you use a terminal emulator where each box-drawing character takes 2 columns, try setting --ambidouble. If the border is still not properly rendered, set --no-unicode.

--border-label[=LABEL]
    Label to print on the horizontal border line. Should be used with one of the following --border options.
    * rounded
    * sharp
    * bold
    * double
    * horizontal
    * top (up)
    * bottom (down)
    e.g.
      # ANSI color codes are supported
      # (with https://github.com/busyloop/lolcat)
      label=$(curl -s http://metaphorpsum.com/sentences/1 | lolcat -f)
      # Border label at the center
      fzf --height=10 --border --border-label="╢ $label ╟" --color=label:italic:black
      # Left-aligned (positive integer)
      fzf --height=10 --border --border-label="╢ $label ╟" --border-label-pos=3 --color=label:italic:black
      # Right-aligned (negative integer) on the bottom line (:bottom)
      fzf --height=10 --border --border-label="╢ $label ╟" --border-label-pos=-3:bottom --color=label:italic:black

--border-label-pos[=N[:top|bottom]]
    Position of the border label on the border line. Specify a positive integer as the column position from the left. Specify a negative integer to right-align the label. Label is printed on the top border line by default, add :bottom to put it on the border line on the bottom. The default value 0 (or center) will put the label at the center of the border line.

--no-unicode
    Use ASCII characters instead of Unicode drawing characters to draw borders, the spinner and the horizontal separator.

--ambidouble
    Set this option if your terminal displays ambiguous width characters (e.g. box-drawing characters for borders) as 2 columns.

--margin=MARGIN
    Comma-separated expression for margins around the finder.
    TRBL Same margin for top, right, bottom, and left
    TB,RL Vertical, horizontal margin
    T,RL,B Top, horizontal, bottom margin
    T,R,B,L Top, right, bottom, left margin
    Each part can be given in absolute number or in percentage relative to the terminal size with % suffix.
    e.g.
         fzf --margin 10%
         fzf --margin 1,5%

--padding=PADDING
    Comma-separated expression for padding inside the border. Padding is distinguishable from margin only when --border option is used.
    e.g.
         fzf --margin 5% --padding 5% --border --preview 'cat {}' \
             --color bg:#222222,preview-bg:#333333
    TRBL Same padding for top, right, bottom, and left
    TB,RL Vertical, horizontal padding
    T,RL,B Top, horizontal, bottom padding
    T,R,B,L Top, right, bottom, left padding

--info=STYLE
    Determines the display style of finder info (match counters).
    default Display on the next line to the prompt
    right Display on the right end of the next line to the prompt
    inline Display on the same line with the default separator ' < '
    inline:SEPARATOR Display on the same line with a non-default separator
    inline-right Display on the right end of the same line
    hidden Do not display finder info

--no-info
    A synonym for --info=hidden

--separator=STR
    The given string will be repeated to form the horizontal separator on the info line (default: '─' or '-' depending on --no-unicode). ANSI color codes are supported.

--no-separator
    Do not display horizontal separator on the info line. A synonym for --separator=''

--scrollbar=CHAR1[CHAR2]
    Use the given character to render scrollbar. (default: '│' or ':' depending on --no-unicode). The optional CHAR2 is used to render scrollbar of the preview window.

--no-scrollbar
    Do not display scrollbar. A synonym for --scrollbar=''

--prompt=STR
    Input prompt (default: '> ')

--pointer=STR
    Pointer to the current line (default: '>')

--marker=STR
    Multi-select marker (default: '>')

--header=STR
    The given string will be printed as the sticky header. The lines are displayed in the given order from top to bottom regardless of --layout option, and are not affected by --with-nth. ANSI color codes are processed even when --ansi is not set.

--header-lines=N
    The first N lines of the input are treated as the sticky header. When --with-nth is set, the lines are transformed just like the other lines that follow.

--header-first
    Print header before the prompt line

--ellipsis=STR
    Ellipsis to show when line is truncated (default: '..')

  Display

             --color='pointer:#E12672,marker:#E17899,prompt:#98BEDE,hl+:#98BC99'

--no-bold
    Do not use bold text

--black
    Use black background

  History

--history=HISTORY_FILE
    Load search history from the specified file and update the file on completion. When enabled, CTRL-N and CTRL-P are automatically remapped to next-history and prev-history.

--history-size=N
    Maximum number of entries in the history file (default: 1000). The file is automatically truncated when the number of the lines exceeds the value.

  Preview

--preview=COMMAND
    Execute the given command for the current line and display the result on the preview window. {} in the command is the placeholder that is replaced to the single-quoted string of the current line. To transform the replacement string, specify field index expressions between the braces (See FIELD INDEX EXPRESSION for the details).
    e.g.
         fzf --preview='head -$LINES {}'
         ls -l | fzf --preview="echo user={3} when={-4..-2}; cat {-1}" --header-lines=1 fzf exports $FZF_PREVIEW_LINES and $FZF_PREVIEW_COLUMNS so that they represent the exact size of the preview window. (It also overrides $LINES and $COLUMNS with the same values but they can be reset by the default shell, so prefer to refer to the ones with FZF_PREVIEW_ prefix.) fzf also exports $FZF_PREVIEW_TOP and $FZF_PREVIEW_LEFT so that the preview command can determine the position of the preview window. A placeholder expression starting with + flag will be replaced to the space-separated list of the selected lines (or the current line if no selection was made) individually quoted. e.g.
         fzf --multi --preview='head -10 {+}'
         git log --oneline | fzf --multi --preview 'git show {+1}' When using a field index expression, leading and trailing whitespace is stripped from the replacement string. To preserve the whitespace, use the s flag. A placeholder expression with f flag is replaced to the path of a temporary file that holds the evaluated list. This is useful when you multi-select a large number of items and the length of the evaluated string may exceed ARG_MAX. e.g.
         # Press CTRL-A to select 100K items and see the sum of all the numbers.
         # This won't work properly without 'f' flag due to ARG_MAX limit.
         seq 100000 | fzf --multi --bind ctrl-a:select-all \
                          --preview "awk '{sum+=\$1} END {print sum}' {+f}" Also, * {q} (or {fzf:query}) is replaced to the current query string
    * {n} is replaced to the zero-based ordinal index of the current item.
      Use {+n} if you want all index numbers when multiple lines are selected.
    Note that you can escape a placeholder pattern by prepending a backslash. Preview window will be updated even when there is no match for the current query if any of the placeholder expressions evaluates to a non-empty string or {q} is in the command template. Since 0.24.0, fzf can render partial preview content before the preview command completes. ANSI escape sequence for clearing the display (CSI 2 J) is supported, so you can use it to implement preview window that is constantly updating. e.g.
          fzf --preview 'for i in $(seq 100000); do
            (( i % 200 == 0 )) && printf "\033[2J"
            echo "$i"
            sleep 0.01
          done' fzf has experimental support for Kitty graphics protocol and Sixel graphics. The following example uses https://github.com/junegunn/fzf/blob/master/bin/fzf-preview.sh script to render an image using either of the protocols inside the preview window. e.g.
          fzf --preview='fzf-preview.sh {}'

--preview-label[=LABEL]
    Label to print on the horizontal border line of the preview window. Should be used with one of the following --preview-window options.
    * border-rounded (default on non-Windows platforms)
    * border-sharp (default on Windows)
    * border-bold
    * border-double
    * border-block
    * border-thinblock
    * border-horizontal
    * border-top
    * border-bottom

--preview-label-pos[=N[:top|bottom]]
    Position of the border label on the border line of the preview window. Specify a positive integer as the column position from the left. Specify a negative integer to right-align the label. Label is printed on the top border line by default, add :bottom to put it on the border line on the bottom. The default value 0 (or center) will put the label at the center of the border line.

--preview-window=[POSITION][,SIZE[%]][,border-BORDER_OPT][,[no]wrap][,[no]follow][,[no]cycle][,[no]hidden][,+SCROLL[OFFSETS][/DENOM]][,~HEADER_LINES][,default][,<SIZE_THRESHOLD(ALTERNATIVE_LAYOUT)]
    POSITION: (default: right)
        up
        down
        left
        right Determines the layout of the preview window. * If the argument contains :hidden, the preview window will be hidden by default until toggle-preview action is triggered. * If size is given as 0, preview window will not be visible, but fzf will still execute the command in the background. * Long lines are truncated by default. Line wrap can be enabled with wrap flag. * Preview window will automatically scroll to the bottom when follow flag is set, similarly to how tail -f works.
        e.g.
              fzf --preview-window follow --preview 'for i in $(seq 100000); do
                echo "$i"
                sleep 0.01
                (( i % 300 == 0 )) && printf "\033[2J"
              done'
    * Cyclic scrolling is enabled with cycle flag. * To change the style of the border of the preview window, specify one of the options for --border with border- prefix. e.g. border-rounded (border with rounded edges, default), border-sharp (border with sharp edges), border-left, border-none, etc. * [:+SCROLL[OFFSETS][/DENOM]] determines the initial scroll offset of the preview window.
      - SCROLL can be either a numeric integer or a single-field index expression that refers to a numeric integer.
      - The optional OFFSETS part is for adjusting the base offset. It should be given as a series of signed integers (-INTEGER or +INTEGER).
      - The final /DENOM part is for specifying a fraction of the preview window height. * ~HEADER_LINES keeps the top N lines as the fixed header so that they are always visible. * default resets all options previously set to the default.
        e.g.
             # Non-default scroll window positions and sizes
             fzf --preview="head {}" --preview-window=up,30%
             fzf --preview="file {}" --preview-window=down,1
             # Initial scroll offset is set to the line number of each line of
             # git grep output *minus* 5 lines (-5)
             git grep --line-number '' |
               fzf --delimiter : --preview 'nl {1}' --preview-window '+{2}-5'
             # Preview with bat, matching line in the middle of the window below
             # the fixed header of the top 3 lines
             #
             # ~3 Top 3 lines as the fixed header
             # +{2} Base scroll offset extracted from the second field
             # +3 Extra offset to compensate for the 3-line header
             # /2 Put in the middle of the preview area
             #
             git grep --line-number '' |
               fzf --delimiter : \
                   --preview 'bat --style=full --color=always --highlight-line {2} {1}' \
                   --preview-window '~3,+{2}+3/2'
             # Display top 3 lines as the fixed header
             fzf --preview 'bat --style=full --color=always {}' --preview-window '~3'
    * You can specify an alternative set of options that are used only when the size
      of the preview window is below a certain threshold. Note that only one
      alternative layout is allowed.
        e.g.
              fzf --preview 'cat {}' --preview-window 'right,border-left,<30(up,30%,border-bottom)'

  Scripting

-q, --query=STR
    Start the finder with the given query

-1, --select-1
    If there is only one match for the initial query (--query), do not start interactive finder and automatically select the only match

-0, --exit-0
    If there is no match for the initial query (--query), do not start interactive finder and exit immediately

-f, --filter=STR
    Filter mode. Do not start interactive finder. When used with --no-sort, fzf becomes a fuzzy-version of grep.

--print-query
    Print query as the first line

--expect=KEY[,..]
    Comma-separated list of keys that can be used to complete fzf in addition to the default enter key. When this option is set, fzf will print the name of the key pressed as the first line of its output (or as the second line if --print-query is also used). The line will be empty if fzf is completed with the default enter key. If --expect option is specified multiple times, fzf will expect the union of the keys. --no-expect will clear the list.
    e.g.
         fzf --expect=ctrl-v,ctrl-t,alt-s --expect=f1,f2,~,@

--read0
    Read input delimited by ASCII NUL characters instead of newline characters

--print0
    Print output delimited by ASCII NUL characters instead of newline characters

--no-clear
    Do not clear finder interface on exit. If fzf was started in full screen mode, it will not switch back to the original screen, so you'll have to manually run tput rmcup to return. This option can be used to avoid flickering of the screen when your application needs to start fzf multiple times in order. (Note that in most cases, it is preferable to use reload action instead.) e.g.
         foo=$(seq 100 | fzf --no-clear) || (
           # Need to manually switch back to the main screen when cancelled
           tput rmcup
           exit 1
         ) && seq "$foo" 100 | fzf

--sync
    Synchronous search for multi-staged filtering. If specified, fzf will launch ncurses finder only after the input stream is complete.
    e.g. fzf --multi | fzf --sync

--listen[=[ADDR:]PORT] --listen-unsafe[=[ADDR:]PORT]
    Start HTTP server and listen on the given address. It allows external processes to send actions to perform via POST method. - If the port number is omitted or given as 0, fzf will automatically choose a port and export it as FZF_PORT environment variable to the child processes - If FZF_API_KEY environment variable is set, the server would require sending an API key with the same value in the x-api-key HTTP header - FZF_API_KEY is required for a non-localhost listen address - To allow remote process execution, use --listen-unsafe e.g.
         # Start HTTP server on port 6266
         fzf --listen 6266
         # Send action to the server
         curl -XPOST localhost:6266 -d 'reload(seq 100)+change-prompt(hundred> )'
         # Get program state in JSON format (experimental)
         # * Make sure NOT to access this endpoint from execute/transform actions
         # as it will result in a timeout
         curl localhost:6266
         # Start HTTP server on port 6266 with remote connections allowed
         # * Listening on non-localhost address requires using an API key
         export FZF_API_KEY="$(head -c 32 /dev/urandom | base64)"
         fzf --listen 0.0.0.0:6266
         # Send an authenticated action
         curl -XPOST localhost:6266 -H "x-api-key: $FZF_API_KEY" -d 'change-query(yo)'
         # Choose port automatically and export it as $FZF_PORT to the child process
         fzf --listen --bind 'start:execute-silent:echo $FZF_PORT > /tmp/fzf-port'

--version
    Display version information and exit

Note that most options have the opposite versions with --no- prefix.

ENVIRONMENT VARIABLES

FZF_DEFAULT_COMMAND
    Default command to use when input is tty. On *nix systems, fzf runs the command with $SHELL -c if SHELL is set, otherwise with sh -c, so in this case make sure that the command is POSIX-compliant.

FZF_DEFAULT_OPTS
    Default options. e.g. export FZF_DEFAULT_OPTS="--extended --cycle"

FZF_API_KEY
    Can be used to require an API key when using --listen option. If not set, no authentication will be required by the server. You can set this value if you need to protect against DNS rebinding and privilege escalation attacks.

EXIT STATUS
0 Normal exit
1 No match
2 Error
130 Interrupted with CTRL-C or ESC

FIELD INDEX EXPRESSION
A field index expression can be a non-zero integer or a range expression ([BEGIN]..[END]). --nth and --with-nth take a comma-separated list of field index expressions.

  Examples
1 The 1st field
2 The 2nd field
-1 The last field
-2 The 2nd to last field
3..5 From the 3rd field to the 5th field
2.. From the 2nd field to the last field
..-3 From the 1st field to the 3rd to the last field
.. All the fields

ENVIRONMENT VARIABLES EXPORTED TO CHILD PROCESSES
fzf exports the following environment variables to its child processes. FZF_LINES Number of lines fzf takes up excluding padding and margin
FZF_COLUMNS Number of columns fzf takes up excluding padding and margin
FZF_TOTAL_COUNT Total number of items
FZF_MATCH_COUNT Number of matched items
FZF_SELECT_COUNT Number of selected items
FZF_QUERY Current query string
FZF_PROMPT Prompt string
FZF_ACTION The name of the last action performed
FZF_PORT Port number when --listen option is used
The following variables are additionally exported to the preview commands. FZF_PREVIEW_TOP Top position of the preview window
FZF_PREVIEW_LEFT Left position of the preview window
FZF_PREVIEW_LINES Number of lines in the preview window
FZF_PREVIEW_COLUMNS Number of columns in the preview window

EXTENDED SEARCH MODE
Unless specified otherwise, fzf will start in "extended-search mode". In this mode, you can specify multiple patterns delimited by spaces, such as: 'wild ^music .mp3$ sbtrkt !rmx You can prepend a backslash to a space (\ ) to match a literal space character.

  Exact-match (quoted)
A term that is prefixed by a single-quote character (') is interpreted as an "exact-match" (or "non-fuzzy") term. fzf will search for the exact occurrences of the string.

  Anchored-match
A term can be prefixed by ^, or suffixed by $ to become an anchored-match term. Then fzf will search for the lines that start with or end with the given string. An anchored-match term is also an exact-match term.

  Negation
If a term is prefixed by !, fzf will exclude the lines that satisfy the term from the result. In this case, fzf performs exact match by default.

  Exact-match by default
If you don't prefer fuzzy matching and do not wish to "quote" (prefixing with ') every word, start fzf with -e or --exact option. Note that when --exact is set, '-prefix "unquotes" the term.

  OR operator
A single bar character term acts as an OR operator. For example, the following query matches entries that start with core and end with either go, rb, or py. e.g. ^core go$ | rb$ | py$

KEY/EVENT BINDINGS
--bind option allows you to bind a key or an event to one or more actions. You can use it to customize key bindings or implement dynamic behaviors. --bind takes a comma-separated list of binding expressions. Each binding expression is KEY:ACTION or EVENT:ACTION. e.g.
     fzf --bind=ctrl-j:accept,ctrl-k:kill-line

  AVAILABLE EVENTS:
start
    Triggered only once when fzf finder starts. Since fzf consumes the input stream asynchronously, the input list is not available unless you use --sync. e.g.
         # Move cursor to the last item and select all items
         seq 1000 | fzf --multi --sync --bind start:last+select-all
load
    Triggered when the input stream is complete and the initial processing of the list is complete. e.g.
         # Change the prompt to "loaded" when the input stream is complete
         (seq 10; sleep 1; seq 11 20) | fzf --prompt 'Loading> ' --bind 'load:change-prompt:Loaded> '
resize
    Triggered when the terminal size is changed. e.g.
         fzf --bind 'resize:transform-header:echo Resized: ${FZF_COLUMNS}x${FZF_LINES}'
result
    Triggered when the filtering for the current query is complete and the result list is ready. e.g.
         # Put the cursor on the second item when the query string is empty
         # * Note that you can't use 'change' event in this case because the second position may not be available
         fzf --sync --bind 'result:transform:[[ -z {fzf:query} ]] && echo "pos(2)"'
change
    Triggered whenever the query string is changed e.g.
         # Move cursor to the first entry whenever the query is changed
         fzf --bind change:first
focus
    Triggered when the focus changes due to a vertical cursor movement or a search result update. e.g.
         fzf --bind 'focus:transform-preview-label:echo [ {} ]' --preview 'cat {}'
         # Any action bound to the event runs synchronously and thus can make the interface sluggish
         # e.g. lolcat isn't one of the fastest programs, and every cursor movement in
         # fzf will be noticeably affected by its execution time
         fzf --bind 'focus:transform-preview-label:echo [ {} ] | lolcat -f' --preview 'cat {}'
         # Beware not to introduce an infinite loop
         seq 10 | fzf --bind 'focus:up' --cycle
one
    Triggered when there's only one match. one:accept binding is comparable to --select-1 option, but the difference is that --select-1 is only effective before the interactive finder starts but one event is triggered by the interactive finder. e.g.
         # Automatically select the only match
         seq 10 | fzf --bind one:accept
zero
    Triggered when there's no match. zero:abort binding is comparable to --exit-0 option, but the difference is that --exit-0 is only effective before the interactive finder starts but zero event is triggered by the interactive finder. e.g.
         # Reload the candidate list when there's no match
         echo $RANDOM | fzf --bind 'zero:reload(echo $RANDOM)+clear-query' --height 3
backward-eof
    Triggered when the query string is already empty and you try to delete it backward. e.g.
         fzf --bind backward-eof:abort

  ACTION COMPOSITION
Multiple actions can be chained using + separator. e.g.
     fzf --multi --bind 'ctrl-a:select-all+accept'
     fzf --multi --bind 'ctrl-a:select-all' --bind 'ctrl-a:+accept'

  ACTION ARGUMENT
An action denoted with (...) suffix takes an argument. e.g.
     fzf --bind 'ctrl-a:change-prompt(NewPrompt> )'
     fzf --bind 'ctrl-v:preview(cat {})' --preview-window hidden If the argument contains parentheses, fzf may fail to parse the expression. In that case, you can use any of the following alternative notations to avoid parse errors.
    action-name[...]
    action-name{...}
    action-name<...>
    action-name~...~
    action-name!...!
    action-name@...@
    action-name#...#
    action-name$...$
    action-name%...%
    action-name^...^
    action-name&...&
    action-name*...*
    action-name;...;
    action-name/.../
    action-name|...|
    action-name:...
    The last one is the special form that frees you from parse errors as it does not expect the closing character. The catch is that it should be the last one in the comma-separated list of key-action pairs.

  COMMAND EXECUTION
With execute(...) action, you can execute arbitrary commands without leaving fzf. For example, you can turn fzf into a simple file browser by binding enter key to less command like follows.
    fzf --bind "enter:execute(less {})" You can use the same placeholder expressions as in --preview. fzf switches to the alternate screen when executing a command. However, if the command is expected to complete quickly, and you are not interested in its output, you might want to use execute-silent instead, which silently executes the command without the switching. Note that fzf will not be responsive until the command is complete. For asynchronous execution, start your command as a background process (i.e. appending &). On *nix systems, fzf runs the command with $SHELL -c if SHELL is set, otherwise with sh -c, so in this case make sure that the command is POSIX-compliant. become(...) action is similar to execute(...), but it replaces the current fzf process with the specified command using execve(2) system call.
    fzf --bind "enter:become(vim {})" become(...) is not supported on Windows.

  RELOAD INPUT
reload(...) action is used to dynamically update the input list without restarting fzf. It takes the same command template with placeholder expressions as execute(...). See https://github.com/junegunn/fzf/issues/1750 for more info. e.g.
     # Update the list of processes by pressing CTRL-R
     ps -ef | fzf --bind 'ctrl-r:reload(ps -ef)' --header 'Press CTRL-R to reload' \
                  --header-lines=1 --layout=reverse
     # Integration with ripgrep
     RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
     INITIAL_QUERY="foobar"
     FZF_DEFAULT_COMMAND="$RG_PREFIX '$INITIAL_QUERY'" \
       fzf --bind "change:reload:$RG_PREFIX {q} || true" \
           --ansi --disabled --query "$INITIAL_QUERY" reload-sync(...) is a synchronous version of reload that replaces the list only when the command is complete. This is useful when the command takes a while to produce the initial output and you don't want fzf to run against an empty list while the command is running. e.g.
     # You can still filter and select entries from the initial list for 3 seconds
     seq 100 | fzf --bind 'load:reload-sync(sleep 3; seq 1000)+unbind(load)'

  TRANSFORM ACTIONS
Actions with transform- prefix are used to transform the states of fzf using the output of an external command. The output of these commands are expected to be a single line of text. e.g.
    fzf --bind 'focus:transform-header:file --brief {}' transform(...) action runs an external command that should print a series of actions to be performed. The output should be in the same format as the payload of HTTP POST request to the --listen server. e.g.
    # Disallow selecting an empty line
    echo -e "1. Hello\n2. Goodbye\n\n3. Exit" |
      fzf --height '~100%' --reverse --header 'Select one' \
          --bind 'enter:transform:[[ -n {} ]] &&
                    echo accept ||
                    echo "change-header:Invalid selection"'

  PREVIEW BINDING
With preview(...) action, you can specify multiple different preview commands in addition to the default preview command given by --preview option. e.g.
     # Default preview command with an extra preview binding
     fzf --preview 'file {}' --bind '?:preview:cat {}'
     # A preview binding with no default preview command
     # (Preview window is initially empty)
     fzf --bind '?:preview:cat {}'
     # Preview window hidden by default, it appears when you first hit '?'
     fzf --bind '?:preview:cat {}' --preview-window hidden

  CHANGE PREVIEW WINDOW ATTRIBUTES
change-preview-window action can be used to change the properties of the preview window. Unlike the --preview-window option, you can specify multiple sets of options separated by '|' characters. e.g.
     # Rotate through the options using CTRL-/
     fzf --preview 'cat {}' --bind 'ctrl-/:change-preview-window(right,70%|down,40%,border-horizontal|hidden|right)'
     # The default properties given by `--preview-window` are inherited, so an empty string in the list is interpreted as the default
     fzf --preview 'cat {}' --preview-window 'right,40%,border-left' --bind 'ctrl-/:change-preview-window(70%|down,border-top|hidden|)'
     # This is equivalent to toggle-preview action
     fzf --preview 'cat {}' --bind 'ctrl-/:change-preview-window(hidden|)'
