    cronjob/tab every 4 hours

    Hi, how can i create a cronjob via the command line, every 4 hours, to pack a zip file:
    cd /home/MyUserNameee/MyDirectory/; tar -cvzf archiv_$(date +%s).tar.gz 1* 2* 3* 4* --remove-files
    At: 1 am, 5 am, 9 am, 13 pm, 17 pm, and 21 pm.
    How can i interrupt temporarily the cronjob?
    Thanks for your answer

    You could put the commands in a bash script, make it executable and then set cron to run the script every four hours. If you want to interrupt it during the script, you can use the sleep command. sleep 60 would be 60 seconds. There are five fields in a cron job plus the command to run the script. The link below has a number of examples and there are numerous tutorials on cron jobs:
