Cron Question

Hunki — Mon, 13 Nov 2006 16:31:24 GMT

I have this defined in my cron entry :

10 * * * * /usr/bin/date >> /export/home/tg123/perf_stat && /usr/ucb/ps -auxww |grep java |grep tg123 |grep default |awk '{print $3" "$4}' >> /export/home/tg123/perf_stat

It runs fine at command line but its not updating the perf_stat file through the cron entry.
Any clues ?

thanks,
hunki

Hi

Make the full command as a script and give the script name in crontab

it may work

Most of the time this is due to path settings.
use set -x at top your script and then trouble shoot

I did try putting it in a script but the date part is not getting updated in the perf file.

Did you check /var/adm/cron/log? maybe you can find something there.

Hi

You can put this single line as two commands in script i think..

try in this way

I did try the two part way, but it ceases to work.

Why are you using "&&" instead of just ";"?
You can also use: awk '{print $3, $4}'

> I did try the two part way, but it ceases to work.

You did it with separate lines in a script? If that fails, you need to fix that first. And as Yang says, use -x.

Hi, just an idea - what about the permissions of the file perf_stat?

Does the user running the crontab the right to write into this file?
