It does not mirror all of `find`'s powerful functionality; however, it does provide just enough features to cover 80% of the use cases you might run into. Features like a well thought-out and convenient syntax, colorized output, smart case, regular expressions, and parallel command execution make `fd` a more than capable successor. + +### Installation + +Head over the [fd][1] GitHub page and check out the section on installation. It covers how to install the application on [macOS,][3] [Debian/Ubuntu][4] [Red Hat][5] , and [Arch Linux][6] . Once installed, you can get a complete overview of all available command-line options by runningfor concise help, or `fd -h` for concise help, or `fd --help` for more detailed help. + +### Simple search + +`fd` is designed to help you easily find files and folders in your operating system's filesystem. The simplest search you can perform is to run `fd` with a single argument, that argument being whatever it is that you're searching for. For example, let's assume that you want to find a Markdown document that has the word `services` as part of the filename: +``` +$ fd services + +downloads/services.md + +``` + +If called with just a single argument, `fd` searches the current directory recursively for any files and/or directories that match your argument. The equivalent search using the built-in `find` command looks something like this: +``` +$ find . -name 'services' + +downloads/services.md + +``` + +As you can see, `fd` is much simpler and requires less typing. Getting more done with less typing is always a win in my book. + +### Files and folders + +You can restrict your search to files or directories by using the `-t` argument, followed by the letter that represents what you want to search for. For example, to find all files in the current directory that have `services` in the filename, you would use: +``` +$ fd -tf services + +downloads/services.md + +``` + +And to find all directories in the current directory that have `services` in the filename: +``` +$ fd -td services + +applications/services + +library/services + +``` + +How about listing all documents with the `.md` extension in the current folder? +``` +$ fd .md + +administration/administration.md + +development/elixir/elixir_install.md + +readme.md + +sidebar.md + +linux.md + +``` + +As you can see from the output, `fd` not only found and listed files from the current folder, but it also found files in subfolders. Pretty neat. You can even search for hidden files using the `-H` argument: +``` +fd -H sessions . + +.bash_sessions + +``` + +### Specifying a directory + +If you want to search a specific directory, the name of the directory can be given as a second argument to `fd`: +``` +$ fd passwd /etc + +/etc/default/passwd + +/etc/pam.d/passwd + +/etc/passwd + +``` + +In this example, we're telling `fd` that we want to search for all instances of the word `passwd` in the `etc` directory. + +### Global searches + +What if you know part of the filename but not the folder? Let's say you downloaded a book on Linux network administration but you have no idea where it was saved. No problem: +``` +fd Administration / + +/Users/pmullins/Documents/Books/Linux/Mastering Linux Network Administration.epub + +``` + +### Wrapping up + +The `fd` utility is an excellent replacement for the `find` command, and I'm sure you'll find it just as useful as I do. To learn more about the command, simply explore the rather extensive man page. + +-------------------------------------------------------------------------------- + +via: https://opensource.com/article/18/6/friendly-alternative-find + +作者：[Patrick H.
