Install fd on Linux
fd doesn’t ship on many systems by default. You’ll need to use your preferred package manager to download and install the application, and then you can run it from within Terminal.
Ubuntu
It will ship on Ubuntu Disco Dingo 19.04, but otherwise you’ll need to download and install it. For Ubuntu and other Debian-based Linux distros, you’ll want to run the following commands to download and install the program. If you need the 32-bit version or a different build, download it from the GitHub releases page for fd.
Debian
On Debian Buster or newer, you can install fd from the official Debian-maintained repository.
Fedora
From Fedora 28, fd can be installed from official package versions.
Arch Linux
Similarly, Arch users can grab fd from the official repos:
Gentoo Linux
Gentoo users can use the following command to download the fd ebuild:
macOS
If you’re running macOS, install Homebrew, then use the command below to install fd:
Using fd on Linux
fd commands have a basic structure of fd pattern compared to find . -iname ‘pattern’. To search for a file by its name, use the following command: This searches within the preset working directory, including subdirectories. To search within a specific directory, specifying it after your search term:
Executing Commands on Results
Like find, fd has a functionality that passes found files to another command for execution. Where find uses find . -iname pattern -exec command, fd uses the -x flag: This command would send all zip files in the directory to the unzip command. You can use the following symbols within the “phrase” of the execute command to pass information in specific ways.
{}: A placeholder is replaced with the path of the search result (files/images/portrait.jpg). {/}: A placeholder that will be replaced by the the filename of the result only, known by UNIX aficionados as the basename (portrait.jpg). {//}: Placeholder replaced with the parent directories of found items (files/images). {.}: Placeholder replaced with the path to the filename, without extension (files/images/portrait). {/.}: Placeholder replaced with the basename of the found item, without extension (portrait).
Consider the following example, using two of the above-cited placeholder symbols:
Other Useful fd Flags
-e: search the extension of files only, with no separating dot. -E pattern: exclude results matching the following pattern. –changed-newer-than date|duration: filter results based on the time since file modification. This will only show files with modification dates later than the specified date. The time can be given a duration that counts backwards from the present moment (10h, 1d, 35min) or can be set to a specific time (“YYYY-MM-DD HH:MM:SS”). –changed-older-than date|duration: Like –change-newer but will show files edited before the specified date or duration, not after. -t: only show files of the specified type (-tf for files, -td for directories, -tx for executables, -tl for symlinks, -te for empty files). -p: search within the entire pathname, not just the filename. -s: force case-sensitivity. By default, fd ignores case unless an uppercase letter is typed in the search pattern. -H: show hidden files and directories within results. -L: follow links into symlinked directories.
fd is a good alternative for the find command. If your experience is that the “find” command is hard to use, then you might have better luck using fd. Try it out and let us know if it is useful to you.
