#!/bin/bash
#SBATCH --job-name=j_Perl
#SBATCH --partition=batch
#SBATCH --mail-type=ALL
#SBATCH --mail-user=username@uga.edu
#SBATCH --ntasks=1
#SBATCH --mem=10gb
#SBATCH --time=08:00:00
#SBATCH --output=Perl.%j.out

  -e commandline        one line of program (several -e's allowed, omit programfile)
  -E commandline        like -e, but enables all optional features

  -T                    enable tainting checks
  -u                    dump core after parsing program
