The whatis command in Linux

If you want information about a package or command you can use the man command (Manual Pages).

You will find a manual page for almost every single package you installed in your Linux Distribution and Linux commands.

To display the manual page for the ls command enter the following in the terminal

man ls


whatis is a new command I recently stumbled across. The whatis command outputs a brief one line description of the package or command extracted from the manual page.

Enter the following command in the terminal
whatis ls


Output
ls (1) - list directory contents


Here is another example using the whatis command
whatis lsb_release


Output
lsb_release (1) - print distribution-specific information
