.TH fzf 1 "Feb 2024" "fzf 0.46.1" "fzf - a command-line fuzzy finder"
.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 well suited for file paths
.br
.BR history " Scoring scheme well suited for command history or any input where chronological ordering is important
Sets \fB--tiebreak=index\fR as well.
.br
.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.
.TP
.BI "--with-nth=" "N[,..]"
Transform the presentation of each line using field index expressions
.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 "--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 \fB--tac\fR as the resulting behavior
can be confusing. Also, consider using \fBtrack\fR action instead of this
option.
.RS
e.g.
\fBgit log --oneline --graph --color=always | nl |
fzf --ansi --track --no-sort --layout=reverse-list\fR
.RE
.TP
.B "--tac"
Reverse the order of the input
.RS
e.g.
\fBhistory | fzf --tac --no-sort\fR
.RE
.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 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 Interface
.TP
.B "-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.
.TP
.B "+m, --no-multi"
Disable multi-select
.TP
.B "--no-mouse"
Disable mouse
.TP
.BI "--bind=" "KEYBINDS"
Comma-separated list of custom key bindings. See \fBKEY/EVENT BINDINGS\fR for
the details.
.TP
.B "--cycle"
Enable cyclic scroll
.TP
.B "--keep-right"
Keep the right end of the line visible when it's too long. Effective only when
the query string is empty.
.TP
.BI "--scroll-off=" "LINES"
Number of screen lines to keep above or below when scrolling to the top or to
the bottom (default: 0).
.TP
.B "--no-hscroll"
Disable horizontal scroll
.TP
.BI "--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.
.TP
.B "--filepath-word"
Make word-wise movements and actions respect path separators. The following
actions are affected:
\fBbackward-kill-word\fR
.br
\fBbackward-word\fR
.br
\fBforward-word\fR
.br
\fBkill-word\fR
.TP
.BI "--jump-labels=" "CHARS"
Label characters for \fBjump\fR and \fBjump-accept\fR
.SS Layout
.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. 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%
.TP
.BI "--min-height=" "HEIGHT"
Minimum height when \fB--height\fR is given in percent (default: 10).
Ignored when \fB--height\fR is not specified.
.TP
.BI "--layout=" "LAYOUT"
Choose the layout (default: default)
.br
.BR default " Display from the bottom of the screen"
.br
.BR reverse " Display from the top of the screen"
.br
.BR reverse-list " Display from the top of the screen, prompt at the bottom"
.br
.TP
.B "--reverse"
A synonym for \fB--layout=reverse\fB
.TP
.BI "--border" [=BORDER_OPT]
Draw border around the finder
.br
.BR rounded " Border with rounded corners (default)"
.br
.BR sharp " Border with sharp corners"
.br
.BR bold " Border with bold lines"
.br
.BR double " Border with double lines"
.br

.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$COLUMNS\fR with the same values but they can be reset
by the default shell, so prefer to refer to the ones with \fBFZF_PREVIEW_\fR
prefix.)
fzf also exports \fB$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 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.
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
Also,
* \fB{q}\fR (or \fB{fzf:query}\fR) is replaced to the current query string
.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 {}'

.SH EXTENDED SEARCH MODE
Unless specified otherwise, fzf will start in "extended-search mode". In this

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
