+
+[fd][1] is a super fast, [Rust][2]-based alternative to the Unix/Linux `find` command. 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.
