Synopsis
watch [options]command
The watch program executes
a given command at regular intervals; the default is every two
seconds. The command is passed to the shell (so be sure to quote or
escape any special characters), and the results are displayed in a
full-screen mode, so you can observe the output conveniently and see
what has changed. For example, watch -n 60
date executes the date
command once a minute, sort of a poor man’s clock. Type ^C to exit.
Useful options
|
|
Set the time between executions, in seconds. |

Highlight differences in the output, to emphasize what has changed from one execution to the next. |
