|
|
|
|
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
|

.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.
|

|
.BR 1 " The 1st field"
|
|
.br

.br
|
|
.BR -1 " The last field"
|
|
.br
|

.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 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|)'
