Using crontab we can schedule task/jobs to run at particular time, date, day
basis.
steps.

1. Login to unix
2. At $prompt 'crontab -l' use this command to check what jobs are already
scheduled.
3. To edit or configure a job use " crontab -e" it will open crontab file which
is same like editing file in vi editor. Now schedule the jobs as per your
requirement.

It look like this
0 2 * * *

The above file will be executed daily at 2 am

1 2 3 4 5 = specific time tags
- where -
1 = Minute (of hour) to activate [0-59]
2 = Hour (of day) to activate [0-23]
3 = Day (of month) to activate [1-31 ... 29,30,31 may not activate during all
months]
4 = Month (of year) to activate [1-12 or 3-letter names "Jan,Feb,Mar"]
5 = Weekday to activate [0-7 or 3-letter names "Mon,Tue,Wed"]
