I'm not in front of an HP, but check out (I think) this file:

/net/interfaces/lan/status/lan0

Cheers

Hi,
have you tried:
ifconfig lan0 | head -1 | awk -F'[<,]' '{print $2}'

Hi,

Try this

$ /usr/sbin/ifconfig lan0|grep lan0|cut -d "<" -f 2|cut -f 1 -d ","

There are countless ways to parse this,
and several to query the nic's state.
Since you began with awk you could do the
parsing like this e.g.

[[ $(ifconfig lan0|awk -F\< '$2~/UP/{split($2,a,",");print a[1]}') = UP ]] && echo up
