My Cronjob is not running
I created a script,

Code:
size=`du -sm`
size=`echo $size | sed 's/.$//'`
size1='30720'
if [ $size -gt $size1 ]
then
{
find /ask/tarballs -type f -name "*.tgz" -mtime +30 -exec ls -l {} \;
find /ask/tarballs -type f -name "*.tgz" -mtime +30 -exec rm -f {} \;
}
else
echo "Directory size doesnt exceed Threshold Limit"
fi

==============
which is in the directory path /ask/tarballs

so i created a cronjob like

Code:
crontab -e

inside that i gave the command

Code:
01 * * * * /ask/tarballs/tar1.sh

then pressed Esc button and saved as :wq
so that it should run every minute..

But the script is not running as per the scheduled task..

Could you help me with this..?

It won't run every minute.

With this setup it will run every hour and 1 minute.g 16.01 , 17.01 etc.
Setup for every minute is all `*'
Code:
* * * * * /ask/tarballs/tar1.sh

Also please use code tags when posting code.

what is your cron log says ?

check under /var/log

Jobs run by cron run in background with no terminal context. Any output from your cron will not go to a terminal. It will go to unix mail for the user who owns the cron (unless you redirect the output to a log file).

Please post what Operating System and version you have and what Shell the script was written to use. The default Shell for cron is usually /bin/sh which on some O/S like Solaris is a very old Bourne Shell.

Please mention which user owns this crontab and post the output from:
Code:
ls -lad /ask/tarballs/tar1.sh

You have new mail in /var/spool/mail/root

If you were logged in as "root" then the cron is owned by root.

Code:
#To find out your Operating System and version:
uname -a
#To find out your normal Shell
echo $SHELL

The mail file is a text file. You can read it with "more" or "tail". In your case at 12:01 GMT you should find it quite easily:
Code:
tail -200 /var/spool/mail/root | more

There are proper ways of reading the mail but we are probably just looking for an error message or other output from your cron.

The permissions of the script file are important. It must be executable by the owner of the cron.
Code:
ls -ald /ask/tarballs/tar1.sh


(POSTS CROSSED)
You need to make the script file executable.
Code:
chmod 755  /ask/tarballs/tar1.sh

Also note that the error message in your post came from /bin/sh which is the default Shell from cron.
If the default Shell from your user is different you will need a shebang line at the top of your script.

The permission is

Code:
-rw-r--r-- 1 root root 294 Feb 19 23:26 /ask/tarballs/tar1.sh

The cronjob results showed as below

Code:
/bin/sh: /ask/tarballs/tar1.sh: Permission denied
