The try-later Script Prindi artikkel
Overview:
The /usr/local/cpanel/scripts/try-later script runs a check command at a specified interval. If the check command returns an error, the script will retry that check command a specified number of times. When the check command succeeds, the script will run the action command. If the check command fails the maximum number of retries, the script will perform an act-finally command.
