UNIX for Dummies Questions & Answers

Code:

#!/bin/sh

echo `date +%F:%T` >> top.out

echo `top -n1` >> top.out

Hi all, i am trying to capture the output of the 'top' command in linux.

when i run the command manually, it works.

However, when i run it as a cronjob,the 'top' output is not being printed to the file,only the date is being printed. i have verified that the cron is working in the /var/log/cron file. any advise?

i found the mistake. i need to specify -b as as option to top.

Code:

top -b -n1

worked.

Check the path of top, eg use

which top

then use the fully qualified path to the top program in the script.


99% of cron problems are due to the assumptions about the environment.
