CICD Version info [中文] [한국어]

fd is a program to find entries in your filesystem. It is a simple, fast and user-friendly alternative to find. While it does not aim to support all of find's powerful functionality, it provides sensible (opinionated) defaults for a majority of use cases.

  • Intuitive syntax: fd PATTERN instead of find -iname '*PATTERN*'.
  • Regular expression (default) and glob-based patterns.
  • Very fast due to parallelized directory traversal.
  • Uses colors to highlight different file types (same as ls).
  • Supports parallel command execution
  • 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 .gitignore, by default.
  • The command name is 50% shorter* than find :-).



How to use

First, to get an overview of all available command line options, you can either run fd -h for a concise help message 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 netflix):

> fd netfl

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

Regular expression search

The search pattern is treated as a regular expression. Here, we search for entries that start with x and end with rc:

> cd /etc
> fd '^x.*rc$'

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:

> fd passwd /etc

List all files, recursively

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):

> cd fd/tests
> fd

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 . or ^:

> fd . fd/tests/

Searching for a particular file extension

Often, we are interested in all files of a particular type. This can be done with the -e (or --extension) option. Here, we search for all Markdown files in the fd repository:

> cd fd
> fd -e md

The -e option can be used in combination with a search pattern:

> fd -e rs mod

Searching for a particular file name

To find files with exactly the provided search pattern, use the -g (or --glob) option:

> fd -g libc.so /usr

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 -H (or --hidden) option:

> fd pre-commit
> fd -H pre-commit

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 .gitignore patterns. To disable this behavior, we can use the -I (or --no-ignore) option:

> fd num_cpu
> fd -I num_cpu

To really search all files and directories, simply combine the hidden and ignore features to show everything (-HI) or use -u/--unrestricted.

Matching the full path

By default, fd only matches the filename of each file. However, using the --full-path or -p option, you can match against the full path.

> fd -p -g '**/.git/config'
> fd -p '.*/lesson-\d+/[a-z]+.(jpg|png)'

Command execution

Instead of just showing the search results, you often want to do something with them. fd provides two ways to execute external commands for each of your search results:

  • The -x/--exec option runs an external command for each of the search results (in parallel).
  • The -X/--exec-batch option launches the external command once, with all search results as arguments.


Recursively find all zip archives and unpack them:

fd -e zip -x unzip

If there are two such files, file1.zip and backup/file2.zip, this would execute unzip file1.zip and unzip backup/file2.zip. The two unzip processes run in parallel (if the files are found fast enough).

Find all *.h and *.cpp files and auto-format them inplace with clang-format -i:

fd -e h -e cpp -x clang-format -i

Note how the -i option to clang-format can be passed as a separate argument. This is why we put the -x option last.

Find all test_*.py files and open them in your favorite editor:

fd -g 'test_*.py' -X vim

Note that we use capital -X here to open a single vim instance. If there are two such files, test_basic.py and lib/test_advanced.py, this will run vim test_basic.py lib/test_advanced.py.

To see details like file permissions, owners, file sizes etc., you can tell fd to show them by running ls for each result:

fd … -X ls -lhd --color=always

This pattern is so useful that fd provides a shortcut. You can use the -l/--list-details option to execute ls in this way: fd … -l.

The -X option is also useful when combining fd with ripgrep (rg) in order to search within a certain class of files, like all C++ source files:

fd -e cpp -e cxx -e h -e hpp -X rg 'std::cout'

Convert all *.jpg files to *.png files:

fd -e jpg -x convert {} {.}.png

Here, {} is a placeholder for the search result. {.} is the same, without the file extension. See below for more details on the placeholder syntax.

The terminal output of commands run from parallel threads using -x will not be interlaced or garbled, so fd -x can be used to rudimentarily parallelize a task run over many files. An example of this is calculating the checksum of each individual file within a directory.

fd -tf -x md5sum > file_checksums.txt

Placeholder syntax

The -x and -X options take a command template as a series of arguments (instead of a single string). If you want to add additional options to fd after the command template, you can terminate it with a \;.

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 (documents/images/party.jpg).
  • {.}: Like {}, but without the file extension (documents/images/party).
  • {/}: A placeholder that will be replaced by the basename of the search result (party.jpg).
  • {//}: The parent of the discovered path (documents/images).
  • {/.}: The basename, with the extension removed (party).

If you do not include a placeholder, fd automatically adds a {} at the end.

Parallel vs. serial execution

For -x/--exec, you can control the number of parallel jobs by using the -j/--threads option. Use --threads=1 for serial execution.

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 (-H) but exclude all matches from .git directories. We can use the -E (or --exclude) option for this. It takes an arbitrary glob pattern as an argument:

> fd -H -E .git …

We can also use this to skip mounted directories:

> fd -E /mnt/external-drive …

.. or to skip certain file types:

> fd -E '*.bak' …

To make exclude-patterns like these permanent, you can create a .fdignore file. They work like .gitignore files, but are specific to fd. For example:

> cat ~/.fdignore

[!NOTE] fd also supports .ignore files that are used by other programs such as rg or ag.

If you want fd to ignore these patterns globally, you can put them in fd's global ignore file. This is usually located in ~/.config/fd/ignore in macOS or Linux, and %APPDATA%\fd\ignore in Windows.

You may wish to include .git/ in your fd/ignore file so that .git directories, and their contents are not included in output if you use the --hidden option.

Deleting files

You can use fd to remove all files and directories that are matched by your search pattern. If you only want to remove files, you can use the --exec-batch/-X option to call rm. For example, to recursively remove all .DS_Store files, run:

> fd -H '^\.DS_Store$' -tf -X rm

If you are unsure, always call fd without -X rm first. Alternatively, use rms "interactive" option:

> fd -H '^\.DS_Store$' -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 rms --recursive/-r flag to remove directories.

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

Command-line options

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.

Let's search my home folder for files that end in [0-9].jpg. It contains ~750.000 subdirectories and about a 4 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 find:

Benchmark 1: find ~ -iregex '.*[0-9]\.jpg$'
  Time (mean ± σ):     19.922 s ±  0.109 s
  Range (min … max):   19.765 s … 20.065 s

find is much faster if it does not need to perform a regular-expression search:

Benchmark 2: find ~ -iname '*[0-9].jpg'
  Time (mean ± σ):     11.226 s ±  0.104 s
  Range (min … max):   11.119 s … 11.466 s

Now let's try the same for fd. Note that fd performs a regular expression search by default. The options -u/--unrestricted option is needed here for a fair comparison. Otherwise fd does not have to traverse hidden folders and ignored paths (see below):

Benchmark 3: fd -u '[0-9]\.jpg$' ~
  Time (mean ± σ):     854.8 ms ±  10.0 ms
  Range (min … max):   839.2 ms … 868.9 ms

For this particular example, fd is approximately 23 times faster than find -iregex and about 13 times faster than find -iname. By the way, both tools found the exact same 546 files :smile:.

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

Concerning fd's speed, a lot of credit goes to the regex and ignore crates that are also used in ripgrep (check it out!).


fd does not find my file!

Remember that fd ignores hidden directories and files by default. It also ignores patterns from .gitignore files. If you want to make sure to find absolutely every possible file, always use the options -u/--unrestricted option (or -HI to enable hidden and ignored files):

> fd -u …

Colorized output

fd can colorize files by extension, just like ls. In order for this to work, the environment variable LS_COLORS has to be set. Typically, the value of this variable is set by the dircolors command which provides a convenient configuration format to define colors for different file formats. On most distributions, LS_COLORS 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.

fd also honors the NO_COLOR environment variable.

fd 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'

"Command not found" for aliases or shell functions

Shell aliases and shell functions can not be used for command execution via fd -x or fd -X. In zsh, you can make the alias global via alias -g myalias="…". In bash, you can use export -f my_function to make available to child processes. You would still need to call fd -x bash -c 'my_function "$1"' bash. For other use cases or shells, use a (temporary) shell script.

Integration with other programs

Using fd with fzf

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 vim <Ctrl-T> 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 .git folders):

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 rofi

rofi is a graphical launch menu application that is able to create menus by reading from stdin. Piping fd output into rofis -dmenu mode creates fuzzy-searchable lists of files and directories.


Create a case-insensitive searchable multi-select list of PDF files under your $HOME directory and open the selection with your configured PDF viewer. To list all file types, drop the -e pdf argument.

fd --type f -e pdf . $HOME | rofi -keep-right -dmenu -i -p FILES -multi-select | xargs -I {} xdg-open {}

To modify the list that is presented by rofi, add arguments to the fd command. To modify the search behaviour of rofi, add arguments to the rofi command.

Using fd with emacs

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

After installing find-file-in-project, add the line (setq ffip-use-rust-fd t) to your ~/.emacs or ~/.emacs.d/init.el file.

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 the output as a tree

To format the output of fd as a file-tree you can use the tree command with --fromfile:

❯ fd | tree --fromfile

This can be more useful than running tree by itself because tree does not ignore any files by default, nor does it support as rich a set of options as fd does to control what to print:

❯ fd --extension rs | tree --fromfile
├── build.rs
└── src
    ├── app.rs
    └── error.rs

On bash and similar you can simply create an alias:

❯ alias as-tree='tree --fromfile'

Using fd with xargs or parallel

Note that fd has a builtin feature for command execution with its -x/--exec and -X/--exec-batch options. If you prefer, you can still use it in combination with xargs:

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

Here, the -0 option tells fd to separate search results by the NULL character (instead of newlines). In the same way, the -0 option of xargs tells it to read the input in this way.
