Problem

I want to prefix stdout lines with something that identifies it.

Solution

script named prefix

#!/bin/bash
cat | sed -u 's/^/['"${1%}"'] /'

Usage:

$ for i in one two three ; do ssh $i cat /etc/resolv.conf | prefix $i ; done

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
