Why not use "ifconfig -a"? On all my systems, it seems to work OK:
ifconfig -a | grep Link\ encap \
| sed -e 's/[ ][ ]*Link.*//;s/:[0-9]*//' \
| sort -u
The sed line removes the "Link encap" and hwaddr stuff and subsequently
removes :[0-9]* tails from alias interfaces. Since that could list
interfaces which have aliases more than once, the sort -u is used.
I'm assuming here that you wouldn't want to use an alias interface as
the name of the external interface...
