A Crontab is a task that consists of four date/time fields and a command field. If there is a match between the four fields then the command field is executed.
"crontab -e".
crontab -e
Just add this to the end of the crontab line > /dev/null 2>&1
Use the cron jobs See /etc/cron.daily /etc/cron.weekly /etc/cron.hourly /etc/crontab and the command crontab
Unix Cron is a daemon ('service') that runs in the background and runs the commands specified in the crontab file at the intervals specified within. This allows someone to easily run a program or script every hour, day, week, etc. The crontab file can be found in two places. Typically, it is located in the /etc directory. Cron also supports multi-user setups, in which case you will also find other 'crontab' files in some distribution-specific location (I believe /var/spool/cron, named after the user that owns the file). More information on Cron can be found by Googling "cron" or "crontab".
crontab -e

You can schedule jobs using cron and the /etc/crontab file, or you can use the "at" command
