Theoretically, it could be done with some form of `set | grep '^ifconfig_.*_alias'` .. however, grep is in /usr/bin, which presents a bit of trouble with using it before configuring the network interfaces :) Hmm any way to do it in pure /bin/sh scripting? /bin/ed comes to mind, but creating a temporary file, ed'ing it, then sourcing the result... rrrrgggggg... did I hear someone whisper 'race condition' from the back rows? :P Not to mention 'ugly' :( G'luck, Peter -- This sentence contains exactly threee erors.
