Hi,

Could be the path problem.Specify the absolute path for the commands when executing using cron.

/usr/bin/date

Thanks,

Hi,

Are you sure this script works?

I thought the test string comparison operator in sh/ksh was a single "=", not "==" like it is in say C.

You're also missing your # on your shebang.

When specifying the script you should use the absolute path in your crontab.

HTH, Paul

Hi,

Since crontab won't inherit the path variables it will fail if absolute paths are not specified in the scripts.

Hi,

You have to specify full path of date
and moreover from crontab also you have to give the full path

No, /usr/bin is added to your crontab PATH.

cron (and at and batch) are commands to run processes on your behalf. But they do not login and will nothing from /etc/profile or your local .profile. Whenever you create a script that will be run without user intervention, always add the required environment, specifically, PATH and other variables. And then test your script with the batch command so you don't have to wait for cron. To use batch:

batch
/fullpath/to/your/script
CTRL-D

When you type batch, it gives you a blank line. Type in the name of your script and the return. Then type CTRL-D (the Ctrl key plus the letter d) and the script will run as a batch job. Once it works in batch, it should work OK in cron.

You can either change your script or change your crontab entry:
. /etc/profile
. ~/.profile

* * * * * . /etc/profile; ~/.profile; script-name parms ...

You might be able to get away without having /etc/profile.
