Usage of Fast File Find fd

$ fd --help

fd 7.4.0

USAGE:
    fd [FLAGS/OPTIONS] [<pattern>] [<path>...]

FLAGS:
    -H, --hidden
            Include hidden directories and files in the search results (default: hidden files and directories are
            skipped). Files and directories are considered to be hidden if their name starts with a `.` sign (dot).

    -I, --no-ignore
            Show search results from files and directories that would otherwise be ignored by '.gitignore', '.ignore' or
            '.fdignore' files
        --no-ignore-vcs
            Show search results from files and directories that would otherwise be ignored by '.gitignore' files
    -s, --case-sensitive
            Perform a case-sensitive search. By default, fd uses case-insensitive searches, unless the pattern contains
            an uppercase character (smart case).

    -i, --ignore-case
            Perform a case-insensitive search. By default, fd uses case-insensitive searches, unless the pattern
            contains an uppercase character (smart case).

    -g, --glob
            Perform a glob-based search instead of a regular expression search
        --regex
            Perform a regular-expression based search (default). This can be used to override --glob
    -F, --fixed-strings
            Treat the pattern as a literal string instead of a regular expression
    -a, --absolute-path
            Shows the full path starting from the root as opposed to relative paths
    -L, --follow
            By default, fd does not descend into symlinked directories. Using this flag, symbolic links are also
            traversed
    -p, --full-path
            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
            Separate search results by the null character (instead of newlines). Useful for piping results to 'xargs'.

        --show-errors
            Enable the display of filesystem errors for situations such as insufficient permissions or dead symlinks
    -h, --help
            Prints help information

    -V, --version
            Prints version information


OPTIONS:
    -d, --max-depth <depth>
            Limit the directory traversal to a given depth. By default, there is no limit on the search depth
    -t, --type <filetype>...
            Filter the search by type (multiple allowable filetypes can be specified):
            'f' or 'file':         regular files
            'd' or 'directory':    directories
            'l' or 'symlink':      symbolic links
            'x' or 'executable':   executable
            'e' or 'empty':        empty files or directories

    -e, --extension <ext>...
            (Additionally) filter search results by their file extension. Multiple allowable file extensions can be
            specified
    -x, --exec <cmd>
            Execute a command for each search result
            All arguments following --exec are taken to be arguments to the command until the argument ';' is
            encountered
            Each occurrence of the following placeholders is substituted by a path derived from the current search
            result before the command is executed:
            '{}':   path
            '{/}':  basename
            '{//}': parent directory
            '{.}':  path without file extension
            '{/.}': basename without file extension

    -X, --exec-batch <cmd>
            Execute a command with all search results at once
            All arguments following --exec-batch are taken to be arguments to the command until the argument ';' is
            encountered
            A single occurrence of the following placeholders is authorized and substituted by the paths derived from the
            search results before the command is executed:
            '{}':   path
            '{/}':  basename
            '{//}': parent directory
            '{.}':  path without file extension
            '{/.}': basename without file extension

    -E, --exclude <pattern>...
            Exclude files/directories that match the given glob pattern. This overrides any other ignore logic. Multiple
            exclude patterns can be specified
        --ignore-file <path>...
            Add a custom ignore-file in '.gitignore' format. These files have a low precedence
    -c, --color <when>
            Declare when to use color for the pattern match output:
            'auto':      show colors if the output goes to an interactive console (default)
            'never':     do not use colorized output
            'always':    always use colorized output

    -j, --threads <num>
            Set number of threads to use for searching & executing (default: number of available CPU cores)

    -S, --size <size>...
            Limit results based on the size of files using the format <+-><NUM><UNIT>.
            '+': file size must be greater than or equal to this
            '-': file size must be less than or equal to this
            'NUM':  The numeric size (e.g. 500)
            'UNIT': The units for NUM. They are not case-sensitive
            Allowed unit values:
            'b':  bytes
            'k':  kilobytes
            'm':  megabytes
            'g':  gigabytes
            't':  terabytes
            'ki': kibibytes
            'mi': mebibytes
            'gi': gibibytes
            'ti': tebibytes

        --changed-within <date|dur>
            Filter results based on the file modification time. The argument can be provided as a specific point in time
            (YYYY-MM-DD HH:MM:SS) or as a duration (10h, 1d, 35min). '--change-newer-than' can be used as an alias
            Examples:
                --changed-within 2weeks
                --change-newer-than '2018-10-27 10:00:00'

        --changed-before <date|dur>
            Filter results based on the file modification time. The argument can be provided as a specific point in time
            (YYYY-MM-DD HH:MM:SS) or as a duration (10h, 1d, 35min). '--change-older-than' can be used as an alias
            Examples:
                --changed-before '2018-10-27 10:00:00'
                --change-older-than 2weeks

        --path-separator <separator>
            Set the path separator to use when printing file paths. The default is the OS-specific separator ('/' on
            Unix, '\' on Windows).

        --search-path <search-path>...
            Provide paths to search as an alternative to the positional <path> argument. Changes the usage to `fd
            [FLAGS/OPTIONS] --search-path <path> --search-path <path2> [<pattern>]`


ARGS:
    <pattern>
            the search pattern: a regular expression unless '--glob' is used (optional)

    <path>...
            The directory where the filesystem search is rooted (optional). If omitted, search the current working
            directory
Note: `fd -h` prints a short and concise overview while `fd --help` gives all details

How to find files with Name on Windows/Mac/Linux

Start a Command line terminal and enter command fd part_of_file_name

$ fd free
src\win\a-free-media-splitter
src\win\a-free-media-splitter\img\easiest-free-video-splitter.png
src\win\a-free-steganography-tool
src\win\a-free-video-end-cropper
src\win\a-free-video-end-cropper\img\easiest-free-crop-end-of-video-audio.png
src\z\eula-freeware.md

fd recursive search path starts from the current directory or the specified directory. If the last part contains string free, it will capture the path as a record. Here the folder src\win\a-free-media-splitter is a record because the last part contains the string free, the file src\win\a-free-media-splitter\img\easiest-free-video-splitter.png is a record too

Filter out directories from file search results, and now when the last part of the path(file name) contains the string free, then the paths will be captured:

$ fd --type file free
src\win\a-free-media-splitter\img\easiest-free-video-splitter.png
src\win\a-free-video-end-cropper\img\easiest-free-crop-end-of-video-audio.png
src\z\eula-freeware.md

Command Line search files with name and exclude directories from results

How to command line find files with specified file extensions

Find files with the md extension and the last part of path contains free:

$ fd --type file --extension md free
src\z\eula-freeware.md

Command Line find files with extension

How to command line find files with size on Windows/Mac/Linux

Syntax:

-S, --size <size>...
        Limit results based on the size of files using the format <+-><NUM><UNIT>.
        '+': file size must be greater than or equal to this
        '-': file size must be less than or equal to this
        'NUM':  The numeric size (e.g. 500)
        'UNIT': The units for NUM. They are not case-sensitive
        Allowed unit values:
        'b':  bytes
        'k':  kilobytes
        'm':  megabytes
        'g':  gigabytes
        't':  terabytes
        'ki': kibibytes
        'mi': mebibytes
        'gi': gibibytes
        'ti': tebibytes

Find files whose file size must be less than or equal to 3 MB and greater than or equal to 1 MB:

$ fd --size -3m --size +1m
src\win\a-life-is-rotation-timer\dl\setup-life-is-rotation-timer.exe

Command Line find file with file size

How to command line search files with date

Syntax:

    --changed-within <date|dur>
            Filter results based on the file modification time. The argument can be provided as a specific point in time
            (YYYY-MM-DD HH:MM:SS) or as a duration (10h, 1d, 35min). '--change-newer-than' can be used as an alias
    Examples:
            --changed-within 2weeks
            --change-newer-than '2018-10-27 10:00:00'
    --changed-before <date|dur>
            Filter results based on the file modification time. The argument can be provided as a specific point in time
            (YYYY-MM-DD HH:MM:SS) or as a duration (10h, 1d, 35min). '--change-older-than' can be used as an alias
    Examples:
            --changed-before '2018-10-27 10:00:00'
            --change-older-than 2weeks

Find files with extension md and changed within 1 hour:

$ fd --type file --extension md --changed-within 1h
src\web\command-line-find-file-with-name-extension-size-in-directory\index.md

Command Line search files with date example

Command line find exclude file extensions/types

Syntax:

-E, --exclude <pattern>...
        Exclude files/directories that match the given glob pattern. This overrides any other ignore logic. Multiple
        exclude patterns can be specified

glob pattern is also called wildcard, and its syntax is similar to .gitignore file, it can match any part of the path, not just the last part

Command line to find files that have changed within 1 day and exclude file extension png:

$ fd --type file --changed-within 1d --exclude '*.png'
src\web\command-line-find-file-with-name-extension-size-in-directory\index.md
src\win\software-to-run-linux-commands-on-windows\index.md

Command line find files and exclude specified file extension

if the name of the directory ends with .png, it is also excluded, because *.png is a glob pattern, not a file extension, and we can verify it by:

$ mkdir test.png && touch test.png/me.md && fd --changed-within 1min --exclude '*png'
src\web\command-line-find-file-with-name-extension-size-in-directory\index.md

I only found the file that is currently be edited (the source of this article)

If I only find the files that have changed within 5 minutes, the result is:

$ fd --type file --changed-within 5min
src\web\command-line-find-file-with-name-extension-size-in-directory\index.md
test.png\me.md

Find files from Command line and compress them to .xz format using tar

The following is an example of find files that I (King Eca) use in real scenarios:

cd ~/mybook/easiestsoft.com
tar --create --xz --file=src.xz $(fd --changed-within 10h --exclude 'how-to/' -E 'zz_*' -E '*.xz' --type file --path-separator '//')
  • Find files that changed within 10 hours
  • Exclude files whose file path contains the folder name how-to
  • Exclude files whose file path contains the (folder or file) name begin with zz_
  • Exclude files whose file path contains the (folder or file) name end with .xz
  • Pass all found files to tar to create .xz compressed file

I used this code with MSYS2, the tar program does not recognize the Windows path separator \, so I used --path-separator '//', but why it should be double / here? I don't know
