how to schedule a script in linux
 

Hi

i have oracle installed on Linux i want to schedule a script "backup.sh" to run in oracle user.



oracle@linux1]crontab -e
*/2 * * * * /tmp/backup.sh

this script does not execute by cron.

BUT

oracle@linux1 tmp] ./backup.sh ------executes successfully


I dont know why the script is not being executed by cron


kindly help me

Make sure crond service is running.

If even cron is running, try this

bash /tmp/backup.sh in the cron file.

Hi,

please, remember that cron commands are executed with a different
environment: for example you do not have the PATH, so commands that
are found from command line are not found from cron.

Just a supposition!

To test, create a simple script which will create a file .
make sure to give the whole path to the commands and files.
See if it works.
Then you know the problem is the script, not cron

show the script content; also if it has an error either the cron job owner or root should get an email from cron re any errors. Try

mailx

from the cmd line as owner and as root to see.
Also, check /var/log/messages.
