The man command can be used to view information in the online Unix manual.
Structure: man [options] [[section] subjects]
man searches for information about a file, command, or directory and then displays it on your screen. Each command is a subject in the manual. If no subject is specified, you must give either a keyword or a file. You can also search for commands that serve a similar purpose. For example, if you wanted more information about the chmod command, you should type:
man chmod
A screen will then appear with information about chmod. Type q to quit.
