How do I use the manual pages?Purdue Engineering Computer Network
One way to find out information about particular programs or commands on your UNIX system is to type man program at your system prompt, where program is the name of the command you want to read about. The man pages are on-line copies of UNIX documentation.
For example, to find out about the who command:
If UNIX responded with "No manual entry for command", then that command is not available on this system or a manual page is not available.
Another good tool is the apropos command. If you type apropos passwd a list of all man pages that contain passwd in their name field will be returned. For example:
You will get this output:
lwpasswd (1L) - changes your Laserwriter account password passwd (5) - password file passwd, chfn, chsh (1) - change password file information passwd.adjunct (5) - user security data file rfpasswd (8) - change RFS host password xcrypt, xencrypt, xdecrypt, passwd2des (3R) - hex encryption and utility routines yppasswd (1) - change your network password in the NIS database yppasswd (3R) - update user password in NIS yppasswd (5) - NIS password file yppasswdd, rpc.yppasswdd (8C) - server for modifying NIS password file ups.ecn.purdue.edu%
You can then use man to view the manual page for the specific command you want. You can also type:
