What is the `man` command?

The man command in Linux is used to display the manual pages for commands, system calls, library functions, and other topics. It provides detailed documentation about how to use a command, including its options and examples.

The basic syntax for using the man command is:

man <command>

For example, to view the manual page for the ls command, you would type:

man ls

You can navigate through the manual pages using the arrow keys, and you can exit the manual page viewer by pressing q. The man command is an essential tool for learning about commands and their usage in Linux.
