ipv4_addrs_<interface> is a much better replacement IMO. It's easy to use and doesn't required the hackish pseudo array traversal used by ifconfig_iface_aliasX.
That might work for simple cases, but how do you specify other parameters beside the IPs if you need to?
What do you need to set? It's sets IP and netmask. It doesn't handle broadcast, but I'd be pretty suprised if that's needed often.
True, not often, but sometimes. I had cases like that in certain environments with bridged networks and arp proxies.
I'm fine with your proposed syntax, as long as all the existing ifconfig possibilities continue to be possible, i.e. no regression.
FWIW, it's HEAD and 6.1. We've actually got the aliases syntax labled as deprecated in the manpage. We might want to add a feature to set the broadcast address.
is needed? Axing ifconfig_iface_aliasX is not needed, but reducing the visiability of the interface in the documentation is probably in order particularly since it's quite fragile since you have to renumber whenever you remove an entry.
Yup, I agree, that's a PITA. That could be solved in the shell code, though, by not enumerating until a number doesn't exist, but instead looking at the set of all shell variables that have been set, similar to this:
set | grep "^ifconfig_${IFACE}_alias" | cut -f1 -d= | ...
Unfortuanly grep in in /usr/bin so can't be used. You could do it with sh variable mangling and case though. Something like:
{ while read _var; do _var=${_var%%=*} case $_var in ifconfig_${IFACE}_alias*) <...> ;; esac done } < `set`
