[gentoo-user] OT: shell question, maybe xargs?

[Adam Carter]

I have one command that dumps out a number of lines of output, and i want
to have another command run multiple times taking a single line contents as
its argument(s) each time. From what i understand of xargs it takes all the
piped input and runs a command once with each of the piped inputs as
another argument.

Eg. say i want to run ethtool against each active interface dumped out by;
ifconfig | grep ^[a-zA-Z] | awk '{print $1}'

Tnx
