.TH fzf 1 "Sep 2025" "fzf 0.66.0" "fzf - a command-line fuzzy finder"

.SH NAME
fzf - a command-line fuzzy finder

.SH SYNOPSIS
fzf [\fIoptions\fR]

.SH DESCRIPTION
fzf is an interactive filter program for any kind of list.

It implements a "fuzzy" matching algorithm, so you can quickly type in patterns
with omitted characters and still get the results you want.

.SH OPTIONS
.SS NOTE
.TP
Most long options have the opposite version with \fB\-\-no\-\fR prefix.

.SS SEARCH
.TP
.B "\-x, \-\-extended"
Extended-search mode. Enabled by default. You can disable it with \fB+x\fR or
\fB\-\-no\-extended\fR.
.TP
.B "\-e, \-\-exact"
Enable exact-match
.TP
.B "\-i, \-\-ignore\-case"
Case-insensitive match (default: smart-case match)
.TP
.B "+i, \-\-no\-ignore\-case"
Case-sensitive match
.TP
.B "\-\-smart\-case"
Smart-case match (default). In this mode, the search is case-insensitive by
default, but it becomes case-sensitive if the query contains any uppercase
letters.
.TP
.B "\-\-literal"
Do not normalize latin script letters for matching.
.TP
.BI "\-\-scheme=" SCHEME
Choose scoring scheme tailored for different types of input.

.RS
.B default
.RS
Generic scoring scheme designed to work well with any type of input.
.RE
.RE

.RS
.B path
.RS
Additional bonus point is only given to the characters after path separator.
You might want to choose this scheme over \fBdefault\fR if you have many files
with spaces in their paths. This also sets \fB\-\-tiebreak=pathname,length\fR,
to prioritize matches occurring in the tail element of a file path.
.RE
.RE

.RS
.B history
.RS
Scoring scheme well suited for command history or any input where chronological
ordering is important. No additional bonus points are given so that we give
more weight to the chronological ordering. This also sets
\fB\-\-tiebreak=index\fR.
.RE
.RE

.RS
fzf chooses \fBpath\fR scheme when the input is a TTY device, where fzf would
start its built-in walker or run \fB$FZF_DEFAULT_COMMAND\fR, and there is no
\fBreload\fR or \fBtransform\fR action bound to \fBstart\fR event. Otherwise,
it chooses \fBdefault\fR scheme.
.RE

.TP
.BI "\-\-algo=" TYPE
Fuzzy matching algorithm (default: v2)

.br
.BR v2 "     Optimal scoring algorithm (quality)"
.br
.BR v1 "     Faster but not guaranteed to find the optimal result (performance)"
.br

.TP
.BI "\-n, \-\-nth=" "N[,..]"
Comma-separated list of field index expressions for limiting search scope.
See \fBFIELD INDEX EXPRESSION\fR for the details. When you use this option with
\fB\-\-with\-nth\fR, the field index expressions are calculated against the
transformed lines (unlike in \fB\-\-preview\fR where fields are extracted from
the original lines) because fzf doesn't allow searching against the hidden
fields.
.TP
.BI "\-\-with\-nth=" "N[,..] or TEMPLATE"
Transform the presentation of each line using the field index expressions.
For advanced transformation, you can provide a template containing field index
expressions in curly braces. When you use a template, the trailing delimiter is
stripped from each expression, giving you more control over the output.
\fB{n}\fR in template evaluates to the zero-based ordinal index of the line.

.RS
e.g.
     # Single expression: drop the first field
     echo foo bar baz | fzf --with-nth 2..

     # Use template to rearrange fields
     echo foo,bar,baz | fzf --delimiter , --with-nth '{n},{1},{3},{2},{1..2}'
.RE
.TP
.BI "\-\-accept\-nth=" "N[,..] or TEMPLATE"
Define which fields to print on accept. The last delimiter is stripped from the
output. For advanced transformation, you can provide a template containing
field index expressions in curly braces. When you use a template, the trailing
delimiter is stripped from each expression, giving you more control over the
output. \fB{n}\fR in template evaluates to the zero-based ordinal index of the
line.

.RS
e.g.
     # Single expression
     echo foo bar baz | fzf --accept-nth 2

     # Template
     echo foo bar baz | fzf --accept-nth 'Index: {n}, 1st: {1}, 2nd: {2}, 3rd: {3}'
.RE
.TP
.B "+s, \-\-no\-sort"
Do not sort the result
.TP
.BI "\-d, \-\-delimiter=" "STR"
Field delimiter regex for \fB\-\-nth\fR, \fB\-\-with\-nth\fR, and field index
expressions (default: AWK-style)
.TP
.B "\-\-tail=NUM"
Maximum number of items to keep in memory. This is useful when you want to
browse an endless stream of data (e.g. log stream) with fzf while limiting
memory usage.

.RS
e.g.
     \fB# Interactive filtering of a log stream
     tail \-f *.log | fzf \-\-tail 100000 \-\-tac \-\-no\-sort \-\-exact\fR
.RE
.TP
.BI "\-\-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
\fBenable\-search\fR or \fBtoggle\-search\fR action.
.TP
.BI "\-\-tiebreak=" "CRI[,..]"
Comma-separated list of sort criteria to apply when the scores are tied.
.br

.br
.BR length "   Prefers line with shorter length"
.br
.BR chunk "    Prefers line with shorter matched chunk (delimited by whitespaces)"
.br
.BR pathname " Prefers line with matched substring in the file name of the path"
.br
.BR begin "    Prefers line with matched substring closer to the beginning"
.br
.BR end "      Prefers line with matched substring closer to the end"
.br
.BR index "    Prefers line that appeared earlier in the input stream"
.br

.br
- Each criterion should appear only once in the list
.br
- \fBindex\fR is only allowed at the end of the list
.br
- \fBindex\fR is implicitly appended to the list when not specified
.br
- Default is \fBlength\fR (or equivalently \fBlength\fR,index)
.br
- If \fBend\fR is found in the list, fzf will scan each line backwards
.SS INPUT/OUTPUT
.TP
.B "\-\-read0"
Read input delimited by ASCII NUL characters instead of newline characters
.TP
.B "\-\-print0"
Print output delimited by ASCII NUL characters instead of newline characters
.TP
.B "\-\-ansi"
Enable processing of ANSI color codes
.TP
.B "\-\-sync"
Synchronous search for multi-staged filtering. If specified, fzf will launch
the finder only after the input stream is complete and the initial filtering
and the associated actions (bound to any of \fBstart\fR, \fBload\fR,
\fBresult\fR, or \fBfocus\fR) are complete.

.RS
e.g. \fB# Avoid rendering both fzf instances at the same time
     fzf \-\-multi | fzf \-\-sync

     # fzf will not render intermediate states
     (sleep 1; seq 1000000; sleep 1) |
       fzf \-\-sync \-\-query 5 \-\-listen \-\-bind start:up,load:up,result:up,focus:change\-header:Ready\fR
.RE
.TP
.B "\-\-no\-tty\-default"
Make fzf search for the current TTY device via standard error instead of
defaulting to \fB/dev/tty\fR. This option avoids issues when launching
emacsclient from within fzf. Alternatively, you can change the default TTY
device by setting \fB--tty-default=DEVICE_NAME\fR.

.SS GLOBAL STYLE
.TP
.BI "\-\-style=" "PRESET"
Apply a style preset [default|minimal|full[:BORDER_STYLE]]
.TP
.BI "\-\-color=" "[BASE_SCHEME][,COLOR_NAME[:ANSI_COLOR][:ANSI_ATTRIBUTES]]..."
Color configuration. The name of the base color scheme is followed by custom
color mappings. Each entry is separated by a comma and/or whitespaces.

.RS
.B BASE SCHEME:
    (default: \fBdark\fR on 256-color terminal, otherwise \fBbase16\fR; If \fBNO_COLOR\fR is set, \fBbw\fR)

.SS DISPLAY MODE
.TP
.BI "\-\-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 \fB~\fR, fzf will automatically determine the height in the
range according to the input size.

  # Will not take up 100% of the screen
  seq 5 | fzf \-\-height=~100%

Adaptive height has the following limitations:
.br
* Cannot be used with top/bottom margin and padding given in percent size
.br
* Negative value is not allowed
.br
* It will not find the right size when there are multi-line items

.TP
.BI "\-\-min\-height=" "HEIGHT[+]"
Minimum height when \fB\-\-height\fR is given as a percentage.
Add \fB+\fR to automatically increase the value according to the other
layout options so that the specified number of items are visible in the list
section (default: \fB10+\fR).
Ignored when \fB\-\-height\fR is not specified or set as an absolute value.
.TP
.BI "\-\-tmux" "[=[center|top|bottom|left|right][,SIZE[%]][,SIZE[%]][,border-native]]"
Start fzf in a tmux popup (default \fBcenter,50%\fR). Requires tmux 3.3 or
later. This option is ignored if you are not running fzf inside tmux.

e.g.
  \fB# Popup in the center with 70% width and height
  fzf \-\-tmux 70%

  # Popup on the left with 40% width and 100% height
  fzf \-\-tmux right,40%

  # Popup on the bottom with 100% width and 30% height
  fzf \-\-tmux bottom,30%

  # Popup on the top with 80% width and 40% height

.SS PREVIEW WINDOW
.TP
.BI "\-\-preview=" "COMMAND"
Execute the given command for the current line and display the result on the
preview window. \fB{}\fR 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 \fBFIELD INDEX
EXPRESSION\fR for the details).

.RS
e.g.
     \fBfzf \-\-preview='head \-$LINES {}'
     ls \-l | fzf \-\-preview="echo user={3} when={\-4..\-2}; cat {\-1}" \-\-header\-lines=1\fR

fzf exports \fB$FZF_PREVIEW_LINES\fR and \fB$FZF_PREVIEW_COLUMNS\fR so that
they represent the exact size of the preview window. (It also overrides
\fB$LINES\fR and \fB$COLUMNS\fR with the same values but they can be reset
by the default shell, so prefer to refer to the ones with \fBFZF_PREVIEW_\fR
prefix.)

fzf also exports \fB$FZF_PREVIEW_TOP\fR and \fB$FZF_PREVIEW_LEFT\fR so that
the preview command can determine the position of the preview window.

A placeholder expression starting with \fB+\fR flag will be replaced to the
space-separated list of the selected items (or the current item if no selection
was made) individually quoted.

e.g.
     \fBfzf \-\-multi \-\-preview='head \-10 {+}'
     git log \-\-oneline | fzf \-\-multi \-\-preview 'git show {+1}'\fR

Similarly, a placeholder expression starting with \fB*\fR flag will be replaced
to the space-separated list of all matched items individually quoted.

Each expression expands to a quoted string, so that it's safe to pass it as an
argument to an external command. So you should not manually add quotes around
the curly braces. But if you don't want this behavior, you can put
\fBr\fR flag (raw) in the expression (e.g. \fB{r}\fR, \fB{r1}\fR, etc).
Use it with caution as unquoted output can lead to broken commands.

When using a field index expression, leading and trailing whitespace is stripped
from the replacement string. To preserve the whitespace, use the \fBs\fR flag.

A placeholder expression with \fBf\fR flag is replaced to the path of
a temporary file that holds the evaluated list. This is useful when you
pass a large number of items and the length of the evaluated string may
exceed \fBARG_MAX\fR.

e.g.
     \fB# See the sum of all the matched numbers
     # This won't work properly without 'f' flag due to ARG_MAX limit.
     seq 100000 | fzf \-\-preview "awk '{sum+=\\$1} END {print sum}' {*f}"\fR

Also,

* \fB{q}\fR is replaced to the current query string
.br
* \fB{q}\fR can contain field index expressions. e.g. \fB{q:1}\fR, \fB{q:2..}\fR, etc.
.br
* \fB{n}\fR is replaced to the zero-based ordinal index of the current item.
  Use \fB{+n}\fR if you want all index numbers when multiple lines are selected.
.br

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 \fB{q}\fR 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 (\fBCSI 2 J\fR) is
supported, so you can use it to implement preview window that is constantly
updating.

e.g.
      \fBfzf \-\-preview 'for i in $(seq 100000); do
        (( i % 200 == 0 )) && printf "\\033[2J"
        echo "$i"
        sleep 0.01
      done'\fR

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.
      \fBfzf \-\-preview='fzf\-preview.sh {}'\fR

* Cyclic scrolling is enabled with \fBcycle\fR flag.

* To hide the scroll offset information on the top right corner, specify
\fBnoinfo\fR.

* To change the style of the border of the preview window, specify one of
the options for \fB\-\-border\fR with \fBborder\-\fR prefix.
e.g. \fBborder\-rounded\fR (border with rounded edges, default),
\fBborder\-sharp\fR (border with sharp edges), \fBborder\-left\fR,
\fBborder\-none\fR, etc.

* In addition to the other border styles, \fBborder\-line\fR style is also
supported, which draws a single separator line between the preview window and
the rest of the interface.

* \fB[:+SCROLL[OFFSETS][/DENOM]]\fR determines the initial scroll offset of the
preview window.

  - \fBSCROLL\fR can be either a numeric integer or a single-field index expression that refers to a numeric integer or {n} to refer to the zero-based ordinal index of the current item.

  - The optional \fBOFFSETS\fR part is for adjusting the base offset. It should be given as a series of signed integers (\fB\-INTEGER\fR or \fB+INTEGER\fR).

  - The final \fB/DENOM\fR part is for specifying a fraction of the preview window height.

.SH 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: \fB'wild
^music .mp3$ sbtrkt !rmx\fR

You can prepend a backslash to a space (\fB\\ \fR) to match a literal space
character.

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

.SS Anchored\-match
A term can be prefixed by \fB^\fR, or suffixed by \fB$\fR 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.

.SS Exact\-boundary\-match (quoted both ends)
A single-quoted term is interpreted as an "exact\-boundary\-match". fzf will
search for the exact occurrences of the string with both ends at the word
boundaries. Unlike in regular expressions, this also sees an underscore as
a word boundary. But the words around underscores are ranked lower and appear
later in the result than the other words around the other types of word
boundaries.

1. xxx foo xxx (highest score)
.br
2. xxx foo_xxx
.br
3. xxx_foo xxx
.br
4. xxx_foo_xxx (lowest score)

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

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

.SS OR operator
A single bar character term acts as an OR operator. For example, the following
query matches entries that start with \fBcore\fR and end with either \fBgo\fR,
\fBrb\fR, or \fBpy\fR.

e.g. \fB^core go$ | rb$ | py$\fR

.SH KEY/EVENT BINDINGS
\fB\-\-bind\fR option allows you to bind \fBa key\fR or \fBan event\fR to one or
more \fBactions\fR. You can use it to customize key bindings or implement
dynamic behaviors.

\fB\-\-bind\fR takes a comma-separated list of binding expressions. Each binding
expression is \fBKEY:ACTION\fR or \fBEVENT:ACTION\fR. You can bind actions to
multiple keys and events by writing comma-separated list of keys and events
before the colon. e.g. \fBKEY1,KEY2,EVENT1,EVENT2:ACTION\fR.

e.g.
     \fBfzf \-\-bind=ctrl\-j:accept,ctrl\-k:kill\-line

     # Load 'ps \-ef' output on start and reload it on CTRL\-R
     fzf \-\-bind 'start,ctrl\-r:reload:ps \-ef'\fR

.SS AVAILABLE EVENTS:
\fIstart\fR
.RS
Triggered only once when fzf finder starts. Since fzf consumes the input stream
asynchronously, the input list is not available unless you use \fI\-\-sync\fR.

e.g.
     \fB# Move cursor to the last item and select all items
     seq 1000 | fzf \-\-multi \-\-sync \-\-bind start:last+select\-all\fR
.RE

\fIload\fR
.RS
Triggered when the input stream is complete and the initial processing of the
list is complete.

e.g.
     \fB# 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> '\fR
.RE

\fIresize\fR
.RS
Triggered when the terminal size is changed.

e.g.
     \fBfzf \-\-bind 'resize:transform\-header:echo Resized: ${FZF_COLUMNS}x${FZF_LINES}'\fR
.RE

\fIresult\fR
.RS
Triggered when the filtering for the current query is complete and the result list is ready.

e.g.
     \fB# 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 {q} ]] && echo "pos(2)"'\fR
.RE
\fIchange\fR
.RS
Triggered whenever the query string is changed

e.g.
     \fB# Move cursor to the first entry whenever the query is changed
     fzf \-\-bind change:first\fR
.RE
\fIfocus\fR
.RS
Triggered when the focus changes due to a vertical cursor movement or a search
result update.

e.g.
     \fBfzf \-\-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\fR
.RE
\fImulti\fR
.RS
Triggered when the multi\-selection has changed.
.RE

\fIone\fR
.RS
Triggered when there's only one match. \fBone:accept\fR binding is comparable
to \fB\-\-select\-1\fR option, but the difference is that \fB\-\-select\-1\fR is only
effective before the interactive finder starts but \fBone\fR event is triggered
by the interactive finder.

e.g.
     \fB# Automatically select the only match
     seq 10 | fzf \-\-bind one:accept\fR
.RE

\fIzero\fR
.RS
Triggered when there's no match. \fBzero:abort\fR binding is comparable to
\fB\-\-exit\-0\fR option, but the difference is that \fB\-\-exit\-0\fR is only
effective before the interactive finder starts but \fBzero\fR event is
triggered by the interactive finder.

e.g.
     \fB# Reload the candidate list when there's no match
     echo $RANDOM | fzf \-\-bind 'zero:reload(echo $RANDOM)+clear\-query' \-\-height 3\fR
.RE

\fIbackward\-eof\fR
.RS
Triggered when the query string is already empty and you try to delete it
backward.

e.g.
     \fBfzf \-\-bind backward\-eof:abort\fR
.RE

\fIjump\fR
.RS
Triggered when successfully jumped to the target item in \fBjump\fR mode.

e.g.
     \fBfzf \-\-bind space:jump,jump:accept\fR
.RE

\fIjump\-cancel\fR
.RS
Triggered when \fBjump\fR mode is cancelled.

e.g.
     \fBfzf \-\-bind space:jump,jump:accept,jump\-cancel:abort\fR
.RE

\fIclick\-header\fR
.RS
Triggered when a mouse click occurs within the header. Sets
\fBFZF_CLICK_HEADER_LINE\fR and \fBFZF_CLICK_HEADER_COLUMN\fR environment
variables starting from 1. It optionally sets \fBFZF_CLICK_HEADER_WORD\fR and
\fBFZF_CLICK_HEADER_NTH\fR if clicked on a word.

e.g.
     \fB# Click on the header line to limit search scope
     ps \-ef | fzf \-\-style full \-\-layout reverse \-\-header\-lines 1 \\
                  \-\-header\-lines\-border bottom \-\-no\-list\-border \\
                  \-\-color fg:dim,nth:regular \\
                  \-\-bind 'click\-header:transform\-nth(
                            echo $FZF_CLICK_HEADER_NTH
                          )+transform\-prompt(
                            echo "$FZF_CLICK_HEADER_WORD> "
                          )'\fR
.RE

\fIclick\-footer\fR
.RS
Triggered when a mouse click occurs within the footer. Sets
\fBFZF_CLICK_FOOTER_LINE\fR and \fBFZF_CLICK_FOOTER_COLUMN\fR environment
variables starting from 1. It optionally sets \fBFZF_CLICK_FOOTER_WORD\fR
if clicked on a word.

Each \fBtransform*\fR action has a corresponding \fBbg\-transform*\fR
variant that runs the command in the background.

.SS ACTION COMPOSITION

Multiple actions can be chained using \fB+\fR separator.

e.g.
     \fBfzf \-\-multi \-\-bind 'ctrl\-a:select\-all+accept'\fR
     \fBfzf \-\-multi \-\-bind 'ctrl\-a:select\-all' \-\-bind 'ctrl\-a:+accept'\fR

Any action after a terminal action that exits fzf, such as \fBaccept\fR or
\fBabort\fR, is ignored.

.SS ACTION ARGUMENT

An action denoted with \fB(...)\fR suffix takes an argument.

e.g.
     \fBfzf \-\-bind 'ctrl\-a:change\-prompt(NewPrompt> )'\fR
     \fBfzf \-\-bind 'ctrl\-v:preview(cat {})' \-\-preview\-window hidden\fR

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.

    \fBaction\-name[...]\fR
    \fBaction\-name{...}\fR
    \fBaction\-name<...>\fR
    \fBaction\-name~...~\fR
    \fBaction\-name!...!\fR
    \fBaction\-name@...@\fR
    \fBaction\-name#...#\fR
    \fBaction\-name$...$\fR
    \fBaction\-name%...%\fR
    \fBaction\-name^...^\fR
    \fBaction\-name&...&\fR
    \fBaction\-name*...*\fR
    \fBaction\-name;...;\fR
    \fBaction\-name/.../\fR
    \fBaction\-name|...|\fR
    \fBaction\-name:...\fR
.RS
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.
.RE

.SS COMMAND EXECUTION

With \fBexecute(...)\fR action, you can execute arbitrary commands without
leaving fzf. For example, you can turn fzf into a simple file browser by
binding \fBenter\fR key to \fBless\fR command like follows.

    \fBfzf \-\-bind "enter:execute(less {})"\fR

You can use the same placeholder expressions as in \fB\-\-preview\fR.

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 \fBexecute\-silent\fR 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 \fB&\fR).

On *nix systems, fzf runs the command with \fB$SHELL \-c\fR if \fBSHELL\fR is
set, otherwise with \fBsh \-c\fR, so in this case make sure that the command is
POSIX-compliant.

\fBbecome(...)\fR action is similar to \fBexecute(...)\fR, but it replaces the
current fzf process with the specified command using \fBexecve(2)\fR system
call.

    \fBfzf \-\-bind "enter:become(vim {})"\fR

.SS RELOAD INPUT

\fBreload(...)\fR action is used to dynamically update the input list
without restarting fzf. It takes the same command template with placeholder
expressions as \fBexecute(...)\fR.

See \fIhttps://github.com/junegunn/fzf/issues/1750\fR for more info.

e.g.
     \fB# 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"\fR

\fBreload\-sync(...)\fR is a synchronous version of \fBreload\fR 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.
     \fB# 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)'\fR

.SS TRANSFORM ACTIONS

Actions with \fBtransform\-\fR 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.
    \fBfzf \-\-bind 'focus:transform\-header:file \-\-brief {}'\fR

\fBtransform(...)\fR 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 \fB\-\-listen\fR server.

e.g.
    \fB# 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"'
    \fR

A common mistake when writing a \fBtransform\fR action is not escaping
placeholder expressions when passing them back to fzf. In the following
example, if you don't escape \fB{}\fR, fzf will immediately replace it with the
single-quoted string of the current item. This causes single quotes to appear
in the header and footer, and the script will break if any item contains
double-quote characters.

    \fBfzf \-\-bind 'focus:transform:[[ $FZF_ACTION =~ up ]] &&
                echo "change\-header()+transform\-footer:echo \\{}" ||
                echo "change\-footer()+transform\-header:echo \\{}"'\fR

.SS TRANSFORM IN THE BACKGROUND

Transform actions are synchronous, meaning fzf becomes unresponsive while the
command runs. To avoid this, each \fBtransform*\fR action has a corresponding
\fBbg\-transform*\fR variant that runs in the background. Unless you need to
chain multiple transform actions where later ones depend on earlier results,
prefer using the \fBbg\fR variant. To cancel currently running background
transform processes, use \fBbg\-cancel\fR action.

.SS PREVIEW BINDING

With \fBpreview(...)\fR action, you can specify multiple different preview
commands in addition to the default preview command given by \fB\-\-preview\fR
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

.SS CHANGE PREVIEW WINDOW ATTRIBUTES

\fBchange\-preview\-window\fR action can be used to change the properties of the
preview window. Unlike the \fB\-\-preview\-window\fR 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|)'
