Reminder Commands

If you ever forget the details of a command, there are two UNIX commands to help you. whatis (command name) will give you a brief reminder of what that command does. man (command name) will show you the entire documentation for the command, which will be extremely long and detailed. If you want to know everything about a command, man is the way to go.

server{username}: whatis ls
ls      ls (1)    - list contents of directory
ls      ls (1b)   - list the contents of a directory
server{username}: man ls
