execute bash file daily ? (OS=UNIX)

Question

Answer 1

You will have to use the cron facility to do this. In particular you will have to edit the crontab file and add a couple of entries.

To run a job daily at 12:30 you would create an entry in the crontab file like so

30 12 * * * /path/to/your/DailyBashScript

to run a job monthly for example on the 1st of the month at 20:45

45 20 1 * * /path/to/yourMonthlyBashScript

Answer 2

You're looking for cron.
