+Replace find with fd on Linux
+======
+The fd command is a popular, user-friendly alternative to the find
+command.
+![Magnifying glass on code][1]
+
+Many Linux programmers use the `find` command every single day of their career. But `find` gives a limited set of filesystem entries, and if you have to do a large set of `find` operations, it's not even very fast. So instead, I prefer to use the Rust `fd` command because it provides sensible defaults that work for most use cases.
+
+As its [README][2] says, "`fd` is a program to find entries in your filesystem. It is a simple, fast, and user-friendly alternative to `find`." It features parallelized directory traversal, so it can search multiple directories at once. It supports regular expressions (regex) and glob-based patterns.
+
+### Install fd
+
+On Linux, you can install `fd` from your software repository (a list of available packages can be found on the [fd page on Repology][3].) For example, on Fedora:
+
+
+```
+`$ sudo dnf install fd-find`
+```
+
+On macOS, use [MacPorts][4] or [Homebrew][5].
+
+Alternately, you can use Rust's Cargo package manager:
+
+
+```
+`$ cargo install fd-find`
+```
+
+### Use fd
+
+To do a simple search, run `fd` after any argument, such as:
+
+
+```
+$ fd sh
+registry/src/github.com-1ecc6299db9ec823/cc-1.0.67/src/bin/gcc-shim.rs
+registry/src/github.com-1ecc6299db9ec823/exa-0.10.1/completions/completions.bash
+registry/src/github.com-1ecc6299db9ec823/exa-0.10.1/completions/completions.fish

+registry/src/github.com-1ecc6299db9ec823/exa-0.10.1/xtests/run.sh
+registry/src/github.com-1ecc6299db9ec823/git2-0.13.18/src/stash.rs
+registry/src/github.com-1ecc6299db9ec823/libc-0.2.94/src/unix/solarish
+registry/src/github.com-1ecc6299db9ec823/libgit2-sys-0.12.19+1.1.0/libgit2/cmake/SelectHashes.cmake
+registry/src/github.com-1ecc6299db9ec823/libgit2-sys-0.12.19+1.1.0/libgit2/include/git2/stash.h
+registry/src/github.com-1ecc6299db9ec823/libgit2-sys-0.12.19+1.1.0/libgit2/include/git2/sys/hashsig.h
+registry/src/github.com-1ecc6299db9ec823/libgit2-sys-0.12.19+1.1.0/libgit2/script/backport.sh
+registry/src/github.com-1ecc6299db9ec823/libgit2-sys-0.12.19+1.1.0/libgit2/script/leaks.sh
+registry/src/github.com-1ecc6299db9ec823/libgit2-sys-0.12.19+1.1.0/libgit2/script/valgrind.sh
+registry/src/github.com-1ecc6299db9ec823/libgit2-sys-0.12.19+1.1.0/libgit2/src/config_snapshot.c
+[...]
+```
+
+If you want to search for a specific directory, provide the directory path as a second argument to `fd`, such as:
+
+
+```
+$ fd passwd /etc
+/etc/pam.d/passwd
+/etc/passwd
+/etc/passwd-
+/etc/security/opasswd
+```
+
+To search for a particular file extension, use `-e` as an option. For example:
+
+
+```
+$ fd . '/home/ssur/exa' -e md
+/home/ssur/exa/README.md
+/home/ssur/exa/devtools/README.md
+/home/ssur/exa/man/exa.1.md
+/home/ssur/exa/man/exa_colors.5.md
+/home/ssur/exa/xtests/README.md
+$
+```
+
+You can also execute a command by providing `-x` or `-X`.
+
+  * The `-x/--exec` option runs an external command for each search result (in parallel).
+  * The `-X/--exec-batch` option launches the external command once with all search results as arguments.
+
+
+
+For example, to recursively find all ZIP archives and unpack them:
+
+
+```
+`$ fd -e zip -x unzip`
+```
+
+Or, to list all files under a particular directory that were changed within the last _n_ number of days, use the `--changed-within` option:
+
+
+```
+$ fd . '/home/ssur/Work/' --changed-within 10d
+/home/ssur/Work/wildfly/connector/src/main/java/org/jboss/as/connector/subsystems/data_sources/JdbcDriverAdd.java
+/home/ssur/Work/wildfly/connector/src/main/java/org/jboss/as/connector/subsystems/data_sources/JdbcExample.java
+[...]
+```
+
+And to search all files that were changed before a specific number of days, use the `--changed-before` _n_ option:
+
+
+```
+`$ fd . '/home/ssur/Work/' --changed-before 365d`
+```
+
+Here, `.` acts as a wildcard entry to instruct `fd` to return all files.
+
+To learn about more the functionalities of `fd`, consult its [documentation][2] on GitHub.
+
+### Conclusion
+
+One thing I especially like about `fd` is that the search pattern is case-insensitive by default, which makes it easier to find things even when you have imprecise knowledge about what you're looking for. Better yet, it _automatically_ switches to case-sensitive if the pattern contains an uppercase character.
+
+Another benefit is that it uses color-coding to highlight different file types.
+
+If you are already using this amazing Rust tool, please let us know your thoughts in the comments.
