In the vast world of Linux, there lies a treasure trove of powerful commands waiting to be discovered. Beyond the commonly used commands like tree, let’s embark on an exploration of six lesser-known yet equally valuable commands: locate, yes, apropos, find, fortune, and findmnt. Each of these commands serves a unique purpose, helping you navigate the Linux file system, generate repetitive input, discover man pages, search for files and directories, receive a daily dose of wisdom, and gain insights into mounted filesystems.
1. locate: Tracking Down Files with Ease:
locate is a versatile tool that helps you find files and directories on your system. It works by searching through a database of file locations that is periodically updated by the updatedb command. To use locate, simply type ‘locate followed by the file or directory name you are looking for.

It is often used in conjunction with other commands to provide repetitive input or to simulate user interaction. For example, ‘yes | command’ will continuously provide a “yes” response to the command, making it ideal for automating tasks that require repetitive confirmation. Additionally, ‘yes string > file’ will create a file filled with the specified string, which can be handy for testing or debugging purposes.
3. apropos: Delving into the World of Man Pages:
apropos is a command that searches through the manual pages (man pages) of Linux commands and displays a list of relevant entries. This is particularly helpful when you’re looking for information about a specific command or topic but don’t know the exact command name. To use apropos, simply type ‘apropos followed by a keyword or phrase related to the topic you’re interested in.
