script exited with error status 127

Question

i wrote some scrip for setting route on specific interface on linux (CentOS 6.0) and put them into Networkmanager script path (/etc/Networkmanager/dispatcher.d) with highest prefix number.(i give execution permition too.)

this is my script:

#!/bin/bash

if [[ "$1" == "eth1" ]] && [[ "$2" == "up" ]]
then
    ip route add 192.XX.XX.0/24 dev eth1 src 192.XX.XX.XX table eth1
    #logger scrip run.
fi

but when eth1 is up i see this error on my syslog-message list:

localhost nm-dispatcher.action: Script '/etc/NetworkManager/dispatcher.d/99-eth' exited with error status 127.

can anyone say where is my mistake??

Solution

I can't comment, so I'll have to reply.

Error 127 means that either command used is not found or your script is not +x. More info from advanced bash-scripting guide at http://tldp.org/LDP/abs/html/exitcodes.html
