Skullbasher and Scriptbasher

Then comes the time when you need to use a program (PowDog) that takes as input only file with format .qpow and you only have the .xyz files.
Moreover this program wants as inline command the atom element. So you script something with bash that transforms .xyz into .qpow and then starts the program N times with different inline command each time.

Mission accomplished.

#!/bin/bash 

for f in *.xyz; do 

   awk '{t=$1; $1=$2; $2=$3; $3=$4; $4=t; print }' $f > $f.qpowd 

done 

for f in *.qpowd; do 

#the "${f%%-*}" only takes the first 2 characters of the file's name 

   ./powdog -i $f -F form.factor -e "${f%%-*}" 

done
