Shell Programming and Scripting

Part of my script throws an error.

Your "cron" job on mitv-t-voms02
/usr/tlrscr/runhc.sh
produced the following output:
/usr/tlrscr/runhc.sh[15]: top: not found
/usr/tlrscr/runhc.sh[17]: top: not found
/usr/tlrscr/runhc.sh[18]: top: not found
syntax error on line 1, teletype

That part of script is :

echo >> /usr/tlrscr/healthchk
top -n 0 | grep -i memory >> /usr/tlrscr/healthchk
echo >> /usr/tlrscr/healthchk
totalmem=`top -n 0 | grep -i memory | awk '{print $2}' | sed 's/M//g'`
free=`top -n 0 | grep -i memory | awk '{print $5}' | sed 's/M//g'`
used=`echo "(($totalmem - $free)/$totalmem) * 100"| bc -l | sed -e "s/\(\.[0-9]\).*/\1/g"`
echo "Physical memory usage is "$used% >> /usr/tlrscr/healthchk
echo >> /usr/tlrscr/healthchk

The script doesn't throw that error when executed manually.
It only happens when it is run by cron at scheduled time.
The "top" is available and can be excuted from command line.

Anyone can help me? Why that part of script fails when run by cron?

Try to use top with the the full path.

Regards

Thanks a lot, it works.
Hemm, how silly of me not trying with the full path?

Thanks again.
