But if you followed John's instructions (repeated below, with slight edits
for clarity), you would get something much better than that. Note the
regexp which will match things like:
FastEthernet0/0/0 is up, line protocol is up
So you'll see the interface names, and then their duplex settings if
they are Ethernet-based.
for rtr in ...list...
clogin -c 'show interfaces | inc (line protocol|duplex|speed)' $rtr >>output.file 2>&1
