What command do you use to display the manual pages for other commands?

The command used to display the manual pages for other commands is "man." The "man" command is an essential tool in Unix-like operating systems, including Linux, that provides a comprehensive set of documentation for commands, system calls, library functions, and other system components.

When you type "man" followed by the name of a command, you receive detailed information on how that command works, including its options, usage examples, and sometimes additional sections explaining its behavior. This is crucial for users to understand commands thoroughly, as the manual pages serve as the primary source of documentation in the Linux environment.

Other options do not serve this purpose in the same way. The "info" command, while it also provides documentation, typically presents information in a different format, focusing on GNU tools specifically. The "help" command offers a brief overview of built-in shell commands but does not provide detailed documentation for external commands. The "readme" is not a standard command-line tool; instead, it's often a text file that might accompany software packages to provide instructions or notes. Thus, "man" is the definitive choice for accessing comprehensive manual pages in Linux.
