FD(1)

๐Ÿ’… FD(1) โ€” find entries in the filesystem

okay bestie, welcome to the FD(1) manual page. This is your group-chat explainer for fd, and weโ€™re keeping every single flag, path, default and caveat because the details are the whole vibe. โœจ

๐ŸŒธ NAME ๐ŸŒธ

fd โ€” find entries in the filesystem

๐Ÿฆ‹ SYNOPSIS ๐Ÿฆ‹

fd [-HIEsiaLp0hV] [-d depth] [-t filetype] [-e ext] [-E exclude] [-c when] [-j num] [-x cmd] [pattern [path...]]

๐ŸŽ€ DESCRIPTION ๐ŸŽ€

okay so fd is a simple, fast and user-friendly alternative to find(1). Sheโ€™s giving main-character energy in your terminal, no cap.

By default, fd uses regular expressions for the pattern. But you can switch that up to simple glob patterns with the --glob option if regex is not the mood.

By default, fd will exclude hidden files and directories, as well as any files that match gitignore rules or ignore rules in .ignore or .fdignore files. So yes, sheโ€™s being a little selective at first โ€” thatโ€™s the default.

If you wish to search all files in a specific directory, you can use '' or . as the search pattern, to match all files. Or you can use the --search-path option to specify the path(s) instead of the positional parameter. Easy.

Options may be given anywhere on the command line. Periodt.

โœจ OPTIONS โœจ

  • -H, --hidden โ€” Include hidden files and directories in the search results (default: hidden files and directories are skipped). The flag can be overridden with --no-hidden.
Ignored files are still excluded unless --no-ignore or --no-ignore-vcs is also used. So donโ€™t think --hidden alone is gonna spill all the tea.
  • -I, --no-ignore โ€” Show search results from files and directories that would otherwise be ignored by:
    • .gitignore
    • .git/info/exclude
    • The global gitignore configuration (by default $HOME/.config/git/ignore)
    • .ignore
    • .fdignore
    • The global fd ignore file (usually $HOME/.config/fd/ignore)

The flag can be overridden with --ignore.

  • -u, --unrestricted โ€” Perform an unrestricted search, including ignored and hidden files. This is an alias for --hidden --no-ignore. Sheโ€™s not holding back at all, literally.
  • --no-ignore-vcs โ€” Show search results from files and directories that would otherwise be ignored by gitignore files including .gitignore, .git/info/exclude, and the global gitignore configuration (core.excludesFile git setting, which defaults to $HOME/.config/git/ignore). The flag can be overridden with --ignore-vcs.
  • --no-require-git โ€” Do not require a git repository to respect gitignores. By default, fd will only respect global gitignore rules, .gitignore rules and local exclude rules if fd detects that you are searching inside a git repository. This flag allows you to relax this restriction such that fd will respect all git related ignore rules regardless of whether youโ€™re searching in a git repository or not. The flag can be overridden with --require-git.
  • --no-ignore-parent โ€” Show search results from files and directories that would otherwise be ignored by gitignore files in parent directories. Yes, she was checking upstairs too; this turns that off.
  • -s, --case-sensitive โ€” Perform a case-sensitive search. By default, fd uses case-insensitive searches, unless the pattern contains an uppercase character (smart case). So uppercase letters are basically the cue. ๐Ÿ’…
  • -i, --ignore-case โ€” Perform a case-insensitive search. By default, fd uses case-insensitive searches, unless the pattern contains an uppercase character (smart case).
  • -g, --glob โ€” Perform a glob-based search instead of a regular expression search. If combined with the --full-path option, ** can be used to match multiple path components. Globs are lowkey iconic for path matching.
  • --regex โ€” Perform a regular-expression based search (default). This can be used to override --glob.
  • -F, --fixed-strings โ€” Treat the pattern as a literal string instead of a regular expression. Note that this also performs substring comparison. If you want to match on an exact filename, consider using --glob or --exact.
  • --exact โ€” Perform an exact match. This is equivalent to --fixed-strings but requires the pattern to match the entire filename (or the full path if --full-path is used), rather than a substring. Special regex characters in the pattern are treated as literal characters. Cannot be used together with --glob or --fixed-strings.
  • --and pattern โ€” Add additional required search patterns, all of which must be matched. Multiple additional patterns can be specified. The patterns are regular expressions, unless --glob or --fixed-strings is used.
  • -a, --absolute-path โ€” Shows the full path starting from the root as opposed to relative paths. The flag can be overridden with --relative-path.
  • -l, --list-details โ€” Use a detailed listing format like ls -l. This is basically an alias for --exec-batch ls -l with some additional ls options. This can be used to see more metadata, to show symlink targets and to achieve a deterministic sort order.
  • -L, --follow โ€” By default, fd does not descend into symlinked directories. Using this flag, symbolic links are also traversed. The flag can be overridden with --no-follow.
  • -p, --full-path โ€” By default, the search pattern is only matched against the filename (or directory name). Using this flag, the pattern is matched against the full path.
  • -0, --print0 โ€” Separate search results by the null character (instead of newlines). Useful for piping results to xargs.
  • --max-results count โ€” Limit the number of search results to count and quit immediately. Sheโ€™ll stop the second she hits the limit, fr fr.
  • -1 โ€” Limit the search to a single result and quit immediately. This is an alias for --max-results=1.
  • -q, --quiet โ€” When the flag is present, the program does not print anything and will instead exit with a code of 0 if there is at least one search result. Otherwise, the exit code will be 1. This is mainly for usage in scripts and can be faster than checking for output because the search can be stopped early after the first match. --has-results can be used as an alias.
  • --show-errors โ€” Enable the display of filesystem errors for situations such as insufficient permissions or dead symlinks.
  • --strip-cwd-prefix [when] โ€” By default, relative paths are prefixed with ./ when -x/--exec, -X/--exec-batch, or -0/--print0 are given, to reduce the risk of a path starting with - being treated as a command line option. Use this flag to change this behavior. If this flag is used without a value, it is equivalent to passing "always". Possible values are:
    • never โ€” Never strip the ./ at the beginning of paths
    • always โ€” Always strip the ./ at the beginning of paths
    • auto โ€” Only strip if used with --exec, --exec-batch, or --print0. That is, it resets to the default behavior.
  • --one-file-system, --mount, --xdev โ€” By default, fd will traverse the file system tree as far as other options dictate. With this flag, fd ensures that it does not descend into a different file system than the one it started in. Comparable to the -mount or -xdev filters of find(1).
  • -h, --help โ€” Print help information.
  • -V, --version โ€” Print version information.
  • -d, --max-depth d โ€” Limit directory traversal to at most d levels of depth. By default, there is no limit on the search depth. She can go as deep as the vibes require.
  • --min-depth d โ€” Only show search results starting at the given depth. See also: --max-depth and --exact-depth.
  • --exact-depth d โ€” Only show search results at the exact given depth. This is an alias for --min-depth <depth> --max-depth <depth>.
  • --prune โ€” Do not traverse into matching directories. If a directory matches, sheโ€™s not going inside. Boundaries, bestie.
  • -t, --type filetype โ€” Filter search by type:
    • f, file โ€” regular files
    • d, dir, directory โ€” directories
    • l, symlink โ€” symbolic links
    • b, block-device โ€” block devices
    • c, char-device โ€” character devices
    • s, socket โ€” sockets
    • p, pipe โ€” named pipes (FIFOs)
    • x, executable โ€” executable (files)
    • e, empty โ€” empty files or directories

This option can be specified more than once to include multiple file types. Searching for --type file --type symlink will show both regular files as well as symlinks. Note that the executable and empty filters work differently: --type executable implies --type file by default. And --type empty searches for empty files and directories, unless either --type file or --type directory is specified in addition.

Examples:

  - Only search for files:
      fd --type file โ€ฆ
      fd -tf โ€ฆ
  - Find both files and symlinks
      fd --type file --type symlink โ€ฆ
      fd -tf -tl โ€ฆ
  - Find executable files:
      fd --type executable
      fd -tx
  - Find empty files:
      fd --type empty --type file
      fd -te -tf
  - Find empty directories:
      fd --type empty --type directory
      fd -te -td
  • -e, --extension ext โ€” Filter search results by extension ext. This option can be used repeatedly to allow for multiple possible extensions. By default, extension filters apply to both files and directories. Use --type to restrict the search to specific types.

If you want to search for files without extension, you can use the regex ^[^.]+$ as a normal search pattern.

  • -E, --exclude glob โ€” Exclude files/directories that match the given glob pattern. This overrides any other ignore logic. Multiple exclude patterns can be specified. Examples:
--exclude '*.pyc'
--exclude node_modules
  • --ignore-contain name โ€” Exclude directories that (directly) contain the given name. This option can be specified multiple times.
  • --ignore-file path โ€” Add a custom ignore-file in .gitignore format. These files have a low precedence.
  • -c, --color when โ€” Declare when to colorize search results:
    • auto โ€” Colorize output when standard output is connected to terminal (default).
    • never โ€” Do not colorize output.
    • always โ€” Always colorize output.
  • --hyperlink โ€” Specify whether the output should use terminal escape codes to indicate a hyperlink to a file url pointing to the path.

Quick thing about that value up there ๐Ÿ‘† โ€” it can be auto, always, or never. ๐Ÿ’…

Right now the default is "never", and if you use the option with no argument at all then "auto" gets used instead. In the future this may get changed to "auto" and "always" โ€” so like, heads up, the vibes may shift one day. ๐Ÿ”ฎ

  • auto โ€” only outputs hyperlinks if color is also enabled, using that as a proxy for whether terminal escape codes are acceptable. iykyk ๐ŸŽ€
  • never โ€” literally never outputs hyperlink escapes. periodt.
  • always โ€” always outputs hyperlink escapes, regardless of your color settings. main character energy, no notes โœจ
  • -j, --threads num โ€” sets the number of threads used for searching & executing (default: however many CPU cores you have available). Parallel slay ๐Ÿ’…
  • -S, --size size โ€” limits results based on file size, using the format <+-><NUM><UNIT>
    • '+' โ€” file size must be greater than or equal to this
    • '-' โ€” file size must be less than or equal to this

If neither '+' nor '-' is given, the file size must be exactly equal to this. no wiggle room bestie ๐Ÿ˜ญ

  • 'NUM' โ€” the numeric size (e.g. 500)
  • 'UNIT' โ€” the units for NUM. They are not case-sensitive. Allowed unit values:
    • 'b' โ€” bytes
    • 'k' โ€” kilobytes (base ten, 10^3 = 1000 bytes)
    • 'm' โ€” megabytes
    • 'g' โ€” gigabytes
    • 't' โ€” terabytes
    • 'ki' โ€” kibibytes (base two, 2^10 = 1024 bytes)
    • 'mi' โ€” mebibytes
    • 'gi' โ€” gibibytes
    • 'ti' โ€” tebibytes
  • --changed-within date|duration โ€” filters results based on the file modification time. Files with modification timestamps greater than the argument get returned. ๐Ÿ•ฐ๏ธ

You can hand it a duration (10h, 1d, 35min), or a specific point in time as full RFC3339 format with time zone, or a date/datetime in the local time zone (YYYY-MM-DD or YYYY-MM-DD HH:MM:SS), or the prefix '@' followed by the number of seconds since the Unix epoch (@[0-9]+). Also, --change-newer-than, --newer or --changed-after can be used as aliases. ๐Ÿ’ซ

Examples:

--changed-within 2weeks
--change-newer-than "2018-10-27 10:00:00"
--newer 2018-10-27
--changed-after @1704067200
  • --changed-before date|duration โ€” filters results based on the file modification time. Files with modification timestamps less than the argument get returned. โณ

Same deal as above: duration (10h, 1d, 35min), or full RFC3339 format with time zone, or a date/datetime in the local time zone (YYYY-MM-DD or YYYY-MM-DD HH:MM:SS), or '@' followed by seconds since the Unix epoch (@[0-9]+). And --change-older-than or --older can be used as aliases. ๐Ÿซถ

Examples:

--changed-before "2018-10-27 10:00:00"
--change-older-than 2weeks
--older @1704067200
  • -o, --owner [user][:group] โ€” filters files by their user and/or group. Format: [(user|uid)][:(group|gid)]. Either side is optional. Put a '!' in front of either side to exclude files instead. ๐Ÿ™ˆ

Examples:

--owner john
--owner :students
--owner "!john:students"
  • -C, --base-directory path โ€” changes the current working directory of fd to whatever path you gave it. Which means search results get shown with respect to that base path. Heads up though: relative paths you pass to fd via the positional path argument or the --search-path option will also be resolved relative to this directory. ๐Ÿ—‚๏ธ
  • --path-separator separator โ€” sets the path separator used when printing file paths. The default is the OS-specific separator ('/' on Unix, '\' on Windows). ๐ŸŒ
  • --search-path search-path โ€” gives you paths to search as an alternative to the positional path argument. It changes the usage to ยดfd [FLAGS/OPTIONS] --search-path PATH --search-path PATH2 [PATTERN]ยด ๐Ÿฆ‹
  • --format fmt โ€” specifies a template string that's used for printing a line for each file found. ๐Ÿ“

These placeholders get substituted into the string for each file before printing:

  • {} โ€” path (of the current search result)
  • {/} โ€” basename
  • {//} โ€” parent directory
  • {.} โ€” path without file extension
  • {/.} โ€” basename without file extension
  • {{ โ€” literal '{' (an escape sequence)
  • }} โ€” literal '}' (an escape sequence)

Notice that you can use "{{" and "}}" to escape "{" and "}" respectively, which is especially useful if you need to include the literal text of one of the above placeholders. iconic escape behavior honestly ๐Ÿ’–

  • -x, --exec command โ€” executes command for each search result in parallel (use --threads=1 if you want sequential command execution). ๐Ÿ”ฅ

Big note: all subsequent positional arguments are considered to be arguments to the command โ€” not to fd. So it's recommended to place the -x/--exec option last. Alternatively, you can supply a ';' argument to end the argument list and continue with more fd options. Most shells require ';' to be escaped: '\;'. ๐Ÿš

This option can be specified multiple times, and in that case all the commands are run for each file found, in the order they're provided. If you do that, you must supply a ';' argument for all but the last command.

If parallelism is enabled, the order commands get executed in is non-deterministic. And even with --threads=1, the order is determined by the operating system and may not be what you expect. So yeah โ€” it's recommended that you don't rely on any ordering of the results. ๐Ÿ’€

Before executing the command, any placeholder patterns in the command get replaced with the corresponding values for the current file. The same placeholders are used as in the "--format" option.

If no placeholder is present, an implicit "{}" at the end is assumed. ๐ŸŽ€

If --print0 is also given, then a null character (\0) will be printed between the output for each found entry. This lets another program easily distinguish the output for each file if the command(s) produce multiple lines. ๐Ÿ™Œ

Examples, bestie:

  • find all *.zip files and unzip them:
fd -e zip -x unzip
  • find *.h and *.cpp files and run "clang-format -i .." for each of them:
fd -e h -e cpp -x clang-format -i
  • Convert all *.jpg files to *.png files:
fd -e jpg -x convert {} {.}.png
  • Run stat for each *.txt file, separated by null characters
fd -0 -e txt -x stat
  • -X, --exec-batch command โ€” executes command once, with all search results as arguments. ๐ŸŽฏ

The order of the arguments is non-deterministic and should not be relied upon. ngl, just don't.

This uses the same placeholders as "--format" and "--exec", but instead of expanding once per command invocation, each argument containing a placeholder is expanded for every file in a batch and passed as separate arguments. ๐Ÿงš

If no placeholder is present, an implicit "{}" at the end is assumed.

Like --exec, subsequent arguments are assumed to be part of command until either the end of command arguments or a ';' argument. See above. โ˜๏ธ

Like --exec, this can be used multiple times, and in that case each command will be run in the order given.

Examples:

  • Find all test_*.py files and open them in your favorite editor:
fd -g 'test_*.py' -X vim

Note that this executes a single "vim" process with all search results as arguments. ๐Ÿ‘‘

  • Find all *.rs files and count the lines with "wc -l ...":
fd -e rs -X wc -l
  • --batch-size size โ€” the maximum number of arguments to pass to the command given with -X. If the number of results is greater than the given size, the command given with -X gets run again with the remaining arguments. A batch size of zero means there is no limit (that's the default), but note that batching might still happen anyway due to OS restrictions on the maximum length of command lines. ๐Ÿ˜ฎโ€๐Ÿ’จ

๐ŸŒˆ PATTERN SYNTAX ๐ŸŒˆ

The regular expression syntax used by fd is documented here:

https://docs.rs/regex/1.0.0/regex/#syntax

The glob syntax is documented here:

https://docs.rs/globset/#syntax

๐ŸŒธ ENVIRONMENT ๐ŸŒธ

  • LS_COLORS โ€” determines how to colorize search results, see dircolors(1). ๐ŸŽจ
  • NO_COLOR โ€” disables colorized output. ๐Ÿ˜” (respect the boundaries bestie)
  • XDG_CONFIG_HOME, HOME โ€” used to locate the global ignore file. If XDG_CONFIG_HOME is set, use $XDG_CONFIG_HOME/fd/ignore. Otherwise, use $HOME/.config/fd/ignore. ๐Ÿ 

๐ŸŽ€ FILES ๐ŸŽ€

  • .fdignore โ€” this file works similarly to a .gitignore file, anywhere in the searched tree, and specifies patterns that should be excluded from the search. BUT it's specific to fd, and it will be used even if the --no-ignore-vcs option is used. special little guy, fr fr ๐Ÿฆ‹
  • $XDG_CONFIG_HOME/fd/ignore โ€” the global ignore file. Unless ignore mode is turned off (such as with --no-ignore), ignore entries in this file will be ignored, as if it was an .fdignore file in the current directory. ๐Ÿ’œ

โœจ EXAMPLES โœจ

Find files and directories that match the pattern 'needle':

$ fd needle

Start a search in a given directory (/var/log):

$ fd nginx /var/log

Find all Python files (all files with the extension .py) in the current directory:

$ fd -e py

Open all search results with vim:

$ fd pattern -X vim

๐Ÿ’… Tips and Tricks ๐Ÿ’…

  • If you add ".git/" to your global ignore file ($XDG_CONFIG_HOME/fd/ignore), then ".git" folders will be ignored by default, even when the --hidden option is used. big brain move ๐Ÿง โœจ
  • You can use a shell alias or a wrapper script in order to pass desired flags to fd by default. For example, if you do not like the default behavior of respecting gitignore, you can use `alias fd="/usr/bin/fd --no-ignore-vcs"` in your .bashrc to create an alias for fd that doesn't ignore git files by default. ๐Ÿš๐Ÿ’–
