Using Man Pages

Using Man Pages

To learn more about a command or program, use the man command, followed by the name of the command. Man pages for Linux and X Window commands are within the /usr/share/man, /usr/local/share/man, and /usr/X11R6/man directories. So, for example, to read the rm command's man page, use the man command like this:

$ man rm

After you press Enter, the less command (a Linux command known as a pager) displays the man page. The less command is a text browser you can use to scroll forward and backward (even sideways) through the document to learn more about the command. Type the letter h to get help, use the forward slash to enter a search string, or press q to quit.

NOTE

Although nearly all the hundreds of GNU commands included with Linux each have a man page, you must use the info command to read detailed information about using a GNU command. For example, to learn even more about bash (which has a rather extensive manual page), use the info command like this:

$ info bash

Press the n and p keys to navigate through the document, or scroll down to a menu item on the screen and press Enter to read about a specific feature. Press q to quit reading.
