LOCATE command in linux

The locate command is often the simplest and quickest way to find the locations of files and directories on Linux and other Unix-like operating systems.

The basic syntax for locate is:
locate [options] name(s)

When used without any options, locate displays every absolute pathname for which the user has access permission that contains any of the names of files and/or directories that are provided to it as arguments (i.e., input data).

To install the locate command run one of these command:

Debain                       >> apt-get install locate
RedHat/CentOS     >> yum install mlocate

When we say that locate searches very quickly, then the first question that comes into mind is that what makes locate so fast?. Well, locate does not search the files on disk rather it searches for file paths in a database. The database is a file that contains information about the files and their path on your system. The locate database file is located at:
/var/lib/mlocate/mlocate.db

The next logical question is, what keeps this mlocate database updated?

Well, there is another utility known as updatedb. When you execute updatedb, it scans the whole system and updates the mlocate.db database file.
