.SH NAME
fzf - a command-line fuzzy finder

.SH SYNOPSIS
fzf [options]

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

.SH OPTIONS
.SS Search mode
.TP
.B "-x, --extended"
Extended-search mode. Since 0.10.9, this is 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"
Case-insensitive match (default: smart-case match)
.TP
.B "+i"
Case-sensitive match
.TP
.B "--literal"
Do not normalize latin script letters for matching.
.TP
.BI "--scheme=" SCHEME
Choose scoring scheme tailored for different types of input.

.br
.BR default "  Generic scoring scheme designed to work well with any type of input"
.br
.BR path "     Scoring scheme for paths (additional bonus point only after path separator)
.br
.BR history "  Scoring scheme for command history (no additional bonus points).
         Sets \fB--tiebreak=index\fR as well.
.br
.TP
.BI "--algo=" TYPE
Fuzzy matching algorithm (default: v2)

.br
.BR v2 "     Optimal scoring algorithm (quality)"

.TP
.BI "-n, --nth=" "N[,..]"
Comma-separated list of field index expressions for limiting search scope.
See \fBFIELD INDEX EXPRESSION\fR for the details.
.TP
.BI "--with-nth=" "N[,..]"

.TP
.BI "-d, --delimiter=" "STR"
Field delimiter regex for \fB--nth\fR and \fB--with-nth\fR (default: AWK-style)
.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.
.SS Search result
.TP
.B "+s, --no-sort"
Do not sort the result
.TP
.B "--tac"

.BR chunk "   Prefers line with shorter matched chunk (delimited by whitespaces)"
.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

.RE
.TP
.B "--no-bold"

.B "--black"

.SS History
.TP
.BI "--history=" "HISTORY_FILE"
Load search history from the specified file and update the file on completion.
When enabled, \fBCTRL-N\fR and \fBCTRL-P\fR are automatically remapped to
\fBnext-history\fR and \fBprev-history\fR.
.TP
.BI "--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.
.SS Preview
.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.)

A placeholder expression starting with \fB+\fR 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.
     \fBfzf --multi --preview='head -10 {+}'
     git log --oneline | fzf --multi --preview 'git show {+1}'\fR

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.

Also, \fB{q}\fR is replaced to the current query string, and \fB{n}\fR is
replaced to zero-based ordinal index of the line. Use \fB{+n}\fR if you want
all index numbers when multiple lines are selected.

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
multi-select a large number of items and the length of the evaluated string may
exceed \fBARG_MAX\fR.

e.g.
     \fB# 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}"\fR

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

.TP
.BI "--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 \fB:bottom\fR to put it on the border line on the bottom. The
default value 0 (or \fBcenter\fR) will put the label at the center of the
border line.

.B POSITION: (default: right)

    \fBright

\fRDetermines the layout of the preview window.

* If the argument contains \fB:hidden\fR, the preview window will be hidden by
default until \fBtoggle-preview\fR 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
\fBwrap\fR flag.

* Preview window will automatically scroll to the bottom when \fBfollow\fR
flag is set, similarly to how \fBtail -f\fR works.

.RS
e.g.
      \fBfzf --preview-window follow --preview 'for i in $(seq 100000); do
        echo "$i"
        sleep 0.01

.RE

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

* 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.

* \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.

  - 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.

* \fB~HEADER_LINES\fR keeps the top N lines as the fixed header so that they
are always visible.

* \fBdefault\fR resets all options previously set to the default.

e.g. \fBfzf --multi | fzf --sync\fR
.RE
.TP
.B "--listen=HTTP_PORT"
Start HTTP server on the given port. It allows external processes to send
actions to perform via POST method.

e.g.
     \fB# 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> )'
     \fR
.TP
.B "--version"
Display version information and exit

.TP
Note that most options have the opposite versions with \fB--no-\fR prefix.

.SH ENVIRONMENT VARIABLES
.TP
.B FZF_DEFAULT_COMMAND
Default command to use when input is tty. 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.
.TP
.B FZF_DEFAULT_OPTS
Default options. e.g. \fBexport FZF_DEFAULT_OPTS="--extended --cycle"\fR

.SH EXIT STATUS
.BR 0 "      Normal exit"
.br
.BR 1 "      No match"
.br
.BR 2 "      Error"
.br
.BR 130 "    Interrupted with \fBCTRL-C\fR or \fBESC\fR"

.SH FIELD INDEX EXPRESSION

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

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

.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 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.

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

\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

.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

.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.

.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 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|)'
