AMD cpu mask script

I wrote this script when we got a HP DL 585 G2 server to add to our dev/test cluster, which is mostly G1s. It checks all the vmx files on a server, and modifies them to have the correct CPU masking for G1/G2 server vmotions to be successful.

#!/bin/bash

PATH=$PATH:/bin:/usr/bin

for i in `vmware-cmd -l`
do
cp -f --reply=yes $i $i.back
if [ `grep -c "cpuid.80000001.edx =" $i` = 0 ]
then
echo 'cpuid.80000001.edx = "-----------0--------H-----------"' >> $i
else
cp -f --reply=yes $i $i.sed1
sed -e 's/cpuid.80000001.edx = "--------------------H-----------"/cpuid.80000001.edx = "-----------0--------H-----------"/g' $i.sed1 > $i.sed2
sed -e 's/cpuid.80000001.edx = "-----------0--------------------"/cpuid.80000001.edx = "-----------0--------H-----------"/g' $i.sed2 > $i
fi
if [ `grep -c cpuid.80000001.edx.amd $i` = 0 ]
then
echo 'cpuid.80000001.edx.amd = "----0R-----0--------H------T----"' >> $i
else
cp -f --reply=yes $i $i.sed1
sed -e "s/cpuid.80000001.edx.amd = \"-----R--------------H------T----\"/cpuid.80000001.edx.amd = \"----0R-----0--------H------T----\"/g" $i.sed1 > $i.sed2
sed -e "s/cpuid.80000001.edx.amd = \"-----R-----0--------H------T----\"/cpuid.80000001.edx.amd = \"----0R-----0--------H------T----\"/g" $i.sed2 > $i.sed3
