Shell Programming and Scripting

I am trying to create a small install script for gentoo. I am trying to research how to pass on information from a command i.e. mii-tool to autodiscover my network settings.

for instance

~ # mii-tool
eth0: no autonegotiation, 100baseTx-HD, link ok
eth1: 10 Mbit, half duplex, no link

shows me that eth0 is up the script then would then execute

net-setup eth0

Seems pretty straightforward...

Code:

net-setup `mii-too | grep 'link ok' | cut -d ':' -f 1 | head -1`

(bourne compatible shell)

Untested

edit: If you want to do something more complex with the output, you can capture it in a variable first:

Code:

myeth=`mii-too | grep 'link ok' | cut -d ':' -f 1 | head -1`
