Did you know there is something called STDERR 2> /dir/files to get results to files.
also you can use symbols like & and | operator to get email incase of failure.

Do you want complete script to be written ? When you say failure what does that mean ?

Also have considered looking at autosys ? It does exactly what you want and much more.

thanks for the mail sir , actually the requirment is very simple . if the scheduled job in cron did not run for some reason we need to this new script to send us a notification that the particular script did not run .

Thanks

Are you checking if the script has issue or cron has issue.

For Script: You need to add to script to email you incase of failure. Share more details of script and there could be a better error handling be suggested.

For Cron: You can add at start of cron

Code:

MAILTO="Your@email" 
0 5 * * * /path/to/script 2>/tmp/file

Check more details in

Code:

man 5 crontab

Incase your server is down which has crontab . Then no email will not send.

Depending on setup I would suggest to use autosys or Control-M

could be 2 things:
- schedule and execution by cron is correct but script generated errors -> thats not cron concern but the responsability of the script
- cron could not execute and you would find that in cron logs or your mbox...

Thanks for the replies . This is my case , i have the below scripts scheduled on cronjob already

Code:

30 06 * * * /opt/db2/db2cad2/dba_scripts/logdelete.sh
16 06 * * 1-5 /opt/db2/db2cad2/dba_scripts/dumpdelete.sh
58 22 * * * /opt/db2/db2cad2/common_scripts/clean_response_cache.sh
00 05 * * * /opt/db2/db2cad2/common_scripts/xfer_userlog_2IQW.sh
00 06,20 * * * /opt/db2/db2cad2/dba_scripts/rendb2diag.sh

Note : the above scheduled script output has not been redirected to any file it wll only send mail if it fails thats it

Now i need to write a new script called check_cronjab.sh and i will schedule that in cronjob , say this new check_cronjab.sh is schedules to run every 30 minutes .

The requirment is like this the check_cronjab.sh which run every 30 minutes has to find if the above scripts like logdelete.sh,dumpdelete.sh,clean_response_cache.sh etc has ran or not if it did not run for some reason then this check_cronjab.sh has to send me a mail that the particular script which has been scheulded to run on so and so time did not run for so and so reason ..

I am not sure if this can be done or not ??

Thanks
