A simple script I used to help automate some tasks while doing Linux From Scratch

lfs.sh

#!/bin/bash

# run this by sourcing it, i.e. "source lfs -t" or ". lfs -t"
# you can make it easier on yourself by making an alias
# for example, alias lfs="source /path/to/lfs.sh"

# colors to use within the script
