CLI Magic: Watch it    Monday, May 23 2005 @ 04:55 PM EDT Contributed by: glosser Linux.com continues their Command-Line-Interface series with a look at "watch". This week we'll take a look at a very simple command called watch. You know what they say, a watched pot never boils. That's why it makes good sense to take advantage of this little tool to watch it for you. Waiting for mail? Want to see if a job has completed? Watch can help. At the CLI, of course. Climb down out of your GUI and take a look. Watch allows you to see a real-time display of the latest output -- the first screenful of output -- from a command. So instead of you having to retype the command 50 times while you wait for whatever to occur, you tell watch to do it for you. By default, watch reissues your command every 2 seconds. The basic format for the watch command is simply watch command. Once started, watch keeps running until it is stopped. You don't want to use watch to programs that keep running. If you do, you'll be sorry. Full tutorial   [ Views: 1618 ]
