If /usr/bin/cmp does not exist, The whole test will fail, then it will
work as heretofore. So, I think we don't need to test if /usr/bin/cmp
exists.
However, if /usr/bin/cmp does not exist, error message will out. So,
we need to supress it as following:
if cmp -s /etc/resolv.conf.std /etc/resolv.conf; then
rm -f /etc/resolv.conf.std
return 0
fi 2>/dev/null
Sincerely,
