Use command line to override parameters in the job script

The command line parameters takes precedence of those in the job script.

Example 1

Consider the job script run1.sh:

#!/bin/bash
#$ -pwd
#$ -l h_data=2G,h_rt=1:00:00

echo 'hello world'

Submission command:

qsub -l h_data=4G run1.sh

results in a job request of:

h_data=4G (from command line, overriding the h_data value in the job script)
h_rt=1:00:00 (from the job script)

Consider the job script run2.sh:

#!/bin/bash
#$ -pwd
#$ -l h_data=2G,h_rt=1:00:00

echo 'hello world'

Submission command:

qsub -l exclusive,h_rt=2:00:00 run2.sh

results in a job request of:

-l exclusive: from command line (new)
h_data=2G: from job script
h_rt=2:00:00: from command line (overriding the h_rt value in the job script)
