gaussfield.sh v0.1

It can be very useful to obtain value of some molecular properties in electric field. I.e. you can get dipole moment of excited states from energies in fields F and -F, hyperpolarizability from analytic polarizability etc. But it's quite annoying to create many very similar Gaussian input files, so I wrote short script to created this files:

#!/usr/bin/env bash
for i in $*
do
        name=`basename $i .com`
        sed -e '/^%/d; /^#/s/$/ Field=X-10/' $i > ${name}-x.com
        sed -e "/^%/d; /^#/s/$/ Field=X+10/" $i > ${name}+x.com
done
