We may use find command to find a file in linux but it is a bit slower than Locate,
locate is a command that help us to find a file efficiently and a bit faster,
it maintains a database called
"/var/lib/mlocate/mlocate.db"
and also has a utility called "updatedb" which keeps this database updated with the
file which
are there in the system. so when we run this command this command runs it update
the database
and updates this database with newly file added. This database is kept by linux system to
keep most updated file list.
