In Unix, what is the man command, and how do I use it to read manual pages?

In Unix, most programs, and many protocols, functions, and file formats, have accompanying manuals. With the man command, you can retrieve the information in the manual and display it as text output on your screen. To use the man command, at the Unix prompt, enter:

man topic
Replace topic with the name of the manual item about which you want more information. For example, to find out more about the FTP command, at the Unix prompt, enter:

man ftp If you are unsure which manual item you want to read, you can do a keyword search. At the Unix prompt, enter:

man -k keyword | more
On some systems, you need to replace man -k with apropos . For example, at the Unix prompt, enter:

apropos keyword | more
In both of the examples above, replace keyword with a specific topic (e.g., ftp , mail ).
