I've got a shell script that runs great when called from the terminal, but when 'cron' calls it, it seems to skip a line. Specifically, it doesn't look like it is calling 'ifconfig.'

The script is this (it's an IP reporter):

Code:

#! /bin/bash
cd /Users/KSE581/
date "+date: %a %b %d %H:%M:%S %Y" > ip_email.txt
echo "to: email@email.com" >> ip_email.txt
echo "subject: subject" >> ip_email.txt
echo "from: email@gmail.com" >> ip_email.txt
echo "" >> ip_email.txt
ifconfig >> ip_email.txt
/usr/sbin/sendmail -t < ip_email.txt

When called by cron (either as root or user), it correctly sends the email, but the ifconfig part of the body is not there. Why won't it run ifconfig?

More searching indicates that while 'ifconfig' works in the bash environment, it doesn't in the sh environment, which is the cron default. I don't even know if I can change that...

you have #!/bin/bash at the top which sets the environment that the script is running under
you might need to call ifconfig with it's full path: /sbin/ifconfig

THANK YOU. In one sentence you fixed what hours of Google hunting could not do.
