The script is not executable.
I refer you to the "chmod" command in my post #6.

Make your script first executable or else use sh to run
Code:
chmod 755  /ask/tarballs/tar1.sh

You can traverse the output of cron to a file say for your error o/p
Code:
* * * * * /ask/tarballs/tar1.sh  >> /tmp/tar-log

This will indeed work providing that the messages come from the script and not from cron itself. The problem error from post #1 would still come out in root mail.
Personally I would put the logfile redirect inside the script and keep crontab as uncluttered as possible.

Cronjob is working now actually. But the problem i got now is,
Actually while running the script tar1.sh as a cronjob, only the else part is running.
i.e
Directory size doesnt exceed Threshold Limit
even though size is greater than size1

but when we execute the script as sh tar1.sh, its deleting the expected files

so wat could be the problem..?? could u please help me with this..?

Can you share below

Add below at top of your script
Code:
set -x

and traverse your output to a file in cron and post the file o/p

size=`du -sm`
Remember that you are running from a root cron.
When running from cron the current working directory is "/".

You probably need a "cd" at the start of the script, for example:

Code:
cd  /ask/tarballs       # Or whatever directory you are measuring
size=`du -sm`

Note: None of my systems have the "-m" switch to "du" so I don't know what the output looks like.
