Watch command Detailed (Linux)

When maintaining the system, it is often necessary to see the system running in real time, such as the number of real-time system connections. With the watch command, Linux can monitor the dynamic changes of the results of each command in real time.

The watch command monitors the dynamic change results of the current command execution in real-time. The common parameters of the watch command are "-n", "-D", "-t", respectively, "How many seconds to refresh", "Highlight dynamic Change", "close the time interval at the top of the command, command display"

The watch command brushes the result every 2 seconds by default. You can change the default value by using the "-n" parameter. Check the current system time every three seconds.
