Using Multiple Commands

Linux allows you to enter multiple commands at one time. The only requirement is that you separate the commands with a semicolon (you can see an example in Figure 11-7).

Want to see how long you have been online? Just combine the date command with Mozilla's command.

date; mozilla; date

Remember that commands are case sensitive, so the command to start Mozilla must be in lowercase to start the browser.

date; mozilla; date
Mon Feb 7 13:26:27 EST 2000
Mon Feb 7 14:28:32 EST 2000

Running the combination of commands prints out the time and date, starts Mozilla, and then prints the time and date again after you close Mozilla. The discrepancy between the two results from the date command shows that you were using Mozilla for just over an hour.
