	~~==File Commands==~~
	~~locate filename~~
	The locate command looks in a premade database that contains a list of all the files on the system. This database is indexed much like a textbook for fast searching, yet can become outdated as files are added and removed from the system, which happens on a regular basis. As a result, the database used for the locate command (/var/lib/mlocate/mlocate.db) is updated each day automatically and can be updated manually by running the updatedb command at a command prompt. You can configure the directories that are searched by the updatedb command by editing the /etc/updatedb.conf file.
	~~find /etc -name inittab~~
	~~updatedb # will update the database~~

	A slower yet more versatile method for locating files on the filesystem is to use the find command. The find command does not use a premade index of files; instead, it searches the directory tree recursively, starting from a certain directory for files that meet a certain criterion.
	~~<br />~~
	~~To use wild card characters with the find command, enclose with "host*"~~
	~~find /etc -name "host*"~~
	~~To find all files starting from the /var directory that have a size greater than 4096K (kilobytes), you can use the following command:~~
	~~find /var -size +4096k~~
	~~Find all the directories only underneath the /boot directory, you can type the following command:~~
	~~find /boot -type d~~
	~~Which Command searches directories that are listed in a special variable called the PATH variable in the BASH shell~~
	~~which ls~~
	~~/bin/ls~~
