show interface statistics for up interfaces only
From cpwiki.net
this will only work from the BASH shell, NOT csh.
[root@myfw ~]# clish -c "show interfaces" | grep -B 1 " Up" | grep "Physical Interface" | grep -v -E "loop0|Tunnel" | awk '{print $3}' | while read LINE; do clish -c "show interface $LINE statistics"; done
