Script to convert MAC Address to format used by PXELinux

This script takes CCCC.CCCC.CCCC or CC:CC:CC:CC or cc:cc:cc:cc and spits out

01-cc-cc-cc-cc for a PXELinux MAC address file on the "first network segment."

#!/bin/sh # Name: pxemac # Usage: pxemac ${MAC Address} OS=`uname -s` type () { TYPE=`echo $1 | sed s/[A-Za-z0-9]*//g` if [ "$TYPE" = ".." ] then return 0 else return 1 fi } linux () { if type $1 then echo $1 | sed -e "s/\./-/g" -e "s/^/01-/" -e "s/-[A-Za-z0-9]\{2\}/&-/g" | tr A-Z a-z else echo $1 | sed -e "s/\:/-/g" -e "s/^/01-/" | tr A-Z a-z fi } nonlinux () { if type $1 then echo $1 | sed -e "s/\./-/g" -e "s/^/01-/" -e "s/-[A-Za-z0-9]\{2\}/&-/g" | tr [A-Z] [a-z] else echo $1 | sed -e "s/\:/-/g" -e "s/^/01-/" | tr '[A-Z]' '[a-z]' fi } if [ "$OS" = "Linux" ] then linux $1 else nonlinux $1 fi
