fd is a simple, fast and user-friendly alternative to find.

While it does not seek to mirror all of find's powerful functionality, it provides sensible (opinionated) defaults for 80% of the use cases.


  • Convenient syntax:
    fd PATTERN
    instead of
    find -iname '*PATTERN*'
  • Colorized terminal output (similar to ls).
  • It's fast (see benchmarks below).
  • Smart case: the search is case-insensitive by default. It switches to case-sensitive if the pattern contains an uppercase character*.
  • Ignores hidden directories and files, by default.
  • Ignores patterns from your
    , by default.
  • Regular expressions.
  • Unicode-awareness.
  • The command name is 50% shorter* than
  • Parallel command execution with a syntax similar to GNU Parallel.




Let's search my home folder for files that end in

. It contains ~190.000 subdirectories and about a million files. For averaging and statistical analysis, I'm using hyperfine. The following benchmarks are performed with a "warm"/pre-filled disk-cache (results for a "cold" disk-cache show the same trends).

Let's start with

: ``` Benchmark #1: find ~ -iregex '.*[0-9].jpg$'

Time (mean ± σ): 7.236 s ± 0.090 s

Range (min … max): 7.133 s … 7.385 s ```

is much faster if it does not need to perform a regular-expression search: ``` Benchmark #2: find ~ -iname '*[0-9].jpg'

Time (mean ± σ): 3.914 s ± 0.027 s

Range (min … max): 3.876 s … 3.964 s ```

Now let's try the same for

. Note that
always performs a regular expression search. The options
are needed for a fair comparison, otherwise
does not have to traverse hidden folders and ignored paths (see below): ``` Benchmark #3: fd -HI '.*[0-9].jpg$' ~

Time (mean ± σ): 811.6 ms ± 26.9 ms

Range (min … max): 786.0 ms … 870.7 ms ``

For this particular example,
is approximately nine times faster than
find -iregex
and about five times faster than
find -iname`. By the way, both tools found the exact same 20880 files :smile:.

Finally, let's run

(this can lead to different search results, of course). If fd does not have to traverse the hidden and git-ignored folders, it is almost an order of magnitude faster: ``` Benchmark #4: fd '[0-9].jpg$' ~

Time (mean ± σ): 123.7 ms ± 6.0 ms

Range (min … max): 118.8 ms … 140.0 ms ```

Note: This is one particular benchmark on one particular machine. While I have performed quite a lot of different tests (and found consistent results), things might be different for you! I encourage everyone to try it out on their own. See this repository for all necessary scripts.

Concerning fd's speed, the main credit goes to the

crates that are also used in ripgrep (check it out!).

Colorized output

can colorize files by extension, just like
. In order for this to work, the environment variable
has to be set. Typically, the value of this variable is set by the
command which provides a convenient configuration format to define colors for different file formats. On most distributions,
should be set already. If you are on Windows or if you are looking for alternative, more complete (or more colorful) variants, see here, here or here.

also honors the
environment variable.

Parallel command execution

If the

option is specified alongside a command template, a job pool will be created for executing commands in parallel for each discovered path as the input. The syntax for generating commands is similar to that of GNU Parallel:
  • {}
    : A placeholder token that will be replaced with the path of the search result (
  • {.}
    : Like
    , but without the file extension (
  • {/}
    : A placeholder that will be replaced by the basename of the search result (
  • {//}
    : Uses the parent of the discovered path (
  • {/.}
    : Uses the basename, with the extension removed (
# Convert all jpg files to png files:
fd -e jpg -x convert {} {.}.png

Unpack all zip files (if no placeholder is given, the path is appended):

fd -e zip -x unzip

Convert all flac files into opus files:

fd -e flac -x ffmpeg -i {} -c:a libopus {.}.opus

Count the number of lines in Rust files (the command template can be terminated with ';'):

fd -x wc -l ; -e rs

The number of threads used for command execution can be set with the

This is the output of

fd -h
. To see the full set of command-line options, use
fd --help
which also includes a much more detailed help text.


First, to get an overview of all available command line options, you can either run

fd -h
for a concise help message (see above) or
fd --help
for a more detailed version.

Simple search

fd is designed to find entries in your filesystem. The most basic search you can perform is to run fd with a single argument: the search pattern. For example, assume that you want to find an old script of yours (the name included

): ``` bash

fd netfl Software/python/imdb-ratings/ ``

If called with just a single argument like this, *fd* searches the current directory recursively
for any entries that *contain* the pattern

Regular expression search

The search pattern is treated as a regular expression. Here, we search for entries that start with

and end with
: ``` bash

cd /etc fd '^x.*rc$' X11/xinit/xinitrc X11/xinit/xserverrc ```

The regular expression syntax used by fd is documented here:

Specifying the root directory

If we want to search a specific directory, it can be given as a second argument to fd: ``` bash

fd passwd /etc /etc/default/passwd /etc/pam.d/passwd /etc/passwd ```

Running fd without any arguments

fd can be called with no arguments. This is very useful to get a quick overview of all entries in the current directory, recursively (similar to

ls -R
): ``` bash

cd fd/tests fd testenv testenv/ ```

If you want to use this functionality to list all files in a given directory, you have to use a catch-all pattern such as

: ``` bash

fd . fd/tests/ testenv testenv/ ```

Searching for a particular file extension

Often, we are interested in all files of a particular type. This can be done with the

) option. Here, we search for all Markdown files in the fd repository: ``` bash

cd fd fd -e md ```


option can be used in combination with a search pattern: ``` bash

fd -e rs mod src/fshelper/ src/lscolors/ tests/testenv/ ```

Hidden and ignored files

By default, fd does not search hidden directories and does not show hidden files in the search results. To disable this behavior, we can use the

) option: ``` bash

fd pre-commit fd -H pre-commit .git/hooks/pre-commit.sample ```

If we work in a directory that is a Git repository (or includes Git repositories), fd does not search folders (and does not show files) that match one of the

patterns. To disable this behavior, we can use the
) option: ``` bash

fd numcpu fd -I numcpu target/debug/deps/libnum_cpus-f5ce7ef99006aa05.rlib ```

To really search all files and directories, simply combine the hidden and ignore features to show everything (


Excluding specific files or directories

Sometimes we want to ignore search results from a specific subdirectory. For example, we might want to search all hidden files and directories (

) but exclude all matches from
directories. We can use the
) option for this. It takes an arbitrary glob pattern as an argument: ``` bash

fd -H -E .git … ```

We can also use this to skip mounted directories: ``` bash

fd -E /mnt/external-drive … ```

.. or to skip certain file types: ``` bash

fd -E '*.bak' … ```

To make exclude-patterns like these permanent, you can create a

file. They work like
files, but are specific to
. For example: ``` bash

cat ~/.fdignore /mnt/external-drive *.bak ``

also supports
files that are used by other programs such as

If you want

to ignore these patterns globally, you can put them in
's global ignore file. This is usually located in
in macOS or Linux, and
in Windows.

Using fd with

If we want to run a command on all search results, we can pipe the output to

: ``` bash

fd -0 -e rs | xargs -0 wc -l ``

Here, the
option tells *fd* to separate search results by the NULL character (instead of
newlines). In the same way, the
option of
xargs` tells it to read the input in this way.

Deleting files

You can use

to remove all files and directories that are matched by your search pattern. If you only want to remove files, you can use the
option to call
. For example, to recursively remove all
files, run: ``` bash

fd -H '^.DSStore$' -tf -X rm

If you are unsure, always call `fd` without `-X rm` first. Alternatively, use `rm`s "interactive"
bash fd -H '^.DSStore$' -tf -X rm -i ```

If you also want to remove a certain class of directories, you can use the same technique. You will have to use

flag to remove directories.

Note: there are scenarios where using

fd … -X rm -r
can cause race conditions: if you have a path like
and want to remove all directories named
, you can end up in a situation where the outer
directory is removed first, leading to (harmless) "'foo/bar/foo': No such file or directory" errors in the


does not find my file!

Remember that

ignores hidden directories and files by default. It also ignores patterns from
files. If you want to make sure to find absolutely every possible file, always use the options
to disable these two features: ``` bash

fd -HI … ```

doesn't seem to interpret my regex pattern correctly

A lot of special regex characters (like

, ..) are also special characters in your shell. If in doubt, always make sure to put single quotes around the regex pattern:
> fd '^[A-Z][0-9]+$'

If your pattern starts with a dash, you have to add

to signal the end of command line options. Otherwise, the pattern will be interpreted as a command-line option. Alternatively, use a character class with a single hyphen character:
> fd -- '-pattern'
> fd '[-]pattern'

Integration with other programs

Using fd with

You can use fd to generate input for the command-line fuzzy finder fzf:

export FZF_DEFAULT_COMMAND='fd --type file'

Then, you can type

on your terminal to open fzf and search through the fd-results.

Alternatively, you might like to follow symbolic links and include hidden files (but exclude

export FZF_DEFAULT_COMMAND='fd --type file --follow --hidden --exclude .git'

You can even use fd's colored output inside fzf by setting:

export FZF_DEFAULT_COMMAND="fd --type file --color=always"
export FZF_DEFAULT_OPTS="--ansi"

For more details, see the Tips section of the fzf README.

Using fd with

The emacs package find-file-in-project can use fd to find files.

After installing

, add the line
(setq ffip-use-rust-fd t)
to your

In emacs, run

M-x find-file-in-project-by-selected
to find matching files. Alternatively, run
M-x find-file-in-project
to list all available files in the project.

Printing fd's output as a tree

To format the output of

similar to the
command, install
and pipe the output of
fd | as-tree

This can be more useful than running

by itself because
does not ignore any files by default, nor does it support as rich a set of options as
does to control what to print:
❯ fd --extension rs | as-tree
└── src
