The system scripts assume a clean shell environment, we can't really protect against an unclean shell - somebody may have made an alias for ifconfig, chmod, chown, or even /bin/ls (yes this is possible!). I think you're probably using '. /etc/netstart ...' which runs the script in the current shell; instead use 'sh /etc/netstart ...' which will solve this (and other possible problems). > However I do not agree with you that ls -nl is pointless and ambiguous. > If we read ls manual, we can find these lines about -n option. > -n List in long format as in -l, but retain user and group IDs in > a > numeric format.

Ah, then I agree that it's not ambiguous, though I still think it's pointless to use -nl when -n does the same.
