what is wrong with cron?
Hey, I have been fighting with this SIMPLE script for a while, and almost going to crazy!!
what I am doing is just get the DNS name for an IP, then echo the result, under bash shell, I can do this using command line, without any problem, $ a=`/usr/sbin/dig +short -x 216.239.37.104` $ echo $a va-in-f104.google.com. Ok, so I wrote this in a script, ran it, no problem, BUT , as long as I use cron to run this simple script, it give me nothing! $ more /tmp/test.sh #!/bin/bash a=`/usr/sbin/dig +short -x 216.239.37.104` echo "just confirm crontab execute this script" > /tmp/result echo $a >> /tmp/result $ more /tmp/result just confirm crontab execute this script $ what is the problem? |
