Using Commands

• When using the operating system, enter commands at the shell prompt on the command line. For example, to display today's date and time, enter:

$ date

• If you make a mistake while typing a command, use the Delete key or Backspace key to erase the incorrect characters and then retype them. An argument is a string of characters that follows a command name. An argument specifies the data the command uses to complete its action.

• For example, the man command gives you information about operating system commands. To display complete information about the date command, enter:

$ man date

cd
