The find command in Linux/Unix is known to be one of the most important and frequently used commands for searching files and directories. It supports different arguments and options for finding files and directories. Even if you can find files and directories in Linux via GUI it will be more friendly and easier to use, but the GUI may require a long time to load with larger sizes.. As a result, experienced System Administrators use only the command-line search because of its reliability, speed, and power.
