 `type` shows what kind of thing you're running, be it an alias, function, or binary program.

-type cmus
+type cd
+type ls
+type -P ls
+type -a cat

 # Whereis the Program
 
-Ask where the `angband` program is, along with all its configuration files:
+Where is `grep` and all its configuration files?
 
-`whereis angband`
+```sh
-
+whereis grep
-Also `which` shows where a binary file (the program) is, 
-
-```bash
-which cmus
 ```
 
-# Search Instantly with `plocate`
+Which one of these is the binary file which you actually use?
 
-You can search every file on the computer instantly by installing `plocate`.
+```sh
-
+which grep
-Once installed, run `sudo updatedb` to create the database of (nearly) every file on the computer.
-
-Check how big the database is:
-
-```bash
-du -h /var/lib/plocate/plocate.db
 ```
 
-Once you have the database, you can find nearly any file instantly.

-`plocate` will not search `/tmp/`, because nobody cares about those files, and won't search inside `/mnt/`, because that's where USB sticks get mounted, so the files keep changing as USB sticks come and go.
-
-Change where `plocate` searches by editing the configuration file at `/etc/updatedb.conf`.
-
-By default, the `/mnt` directory is 'pruned' from the database.
-So if you want to search `/mnt` for videos, remove the word `/mnt` from the configuration file.
