We can use cron to schedule script execution at a fixed interval, such as adding such an entry in crontab to enable the script to run automatically 10 o'clock in the morning every day:


* * */home/sh/disklog.sh/home/log/diskusg.log

Execute the CRONTAB-E command, add the line above and save it.

can also be performed manually:

$./disklog.sh
