    Hi,

    I tried changing to /sbin/ip route and then the script went past that.
    I did some more debugging to figure out what was going on. What I
    found was that if I put the following at the very top

    echo BEFORE
    false
    echo AFTER

    The script would never reach till AFTER. This was because of set -e
    line. I removed the set -e line and then I will get both BEFORE and
    AFTER. Reading sh man page seems to indicate that doing "set -e"
    forces the script to exit immediately if any of it's "untested"
    command exits with non-zero values. I removed set -e and now it is
    working as expected.

    thanks for your help,
    Osho
