[gradsusr] passing whitespace from bash to grasds run

[Huddleston, John]

Bash scripts treat any white space as delimiters so set the following to limit it to linefeeds:
export IFS=$'\n'

Next, put your two word arguments in single quotes:
'foo bar'

John Huddleston

Here is  a test script testIFS.sh, run it by typing ./testIFS.sh one 'foo bar'

#!/bin/bash
if [ $# -lt 2 ];then
        echo "pass at least two arguments"
        exit
fi
export IFS=$'\n'
icnt=0
for i in $*
do
        icnt=`expr $icnt + 1`
        echo "$icnt: $i"
done

Subject: [gradsusr] passing whitespace from bash to grasds run

Hi all,

is it possible to pass arguments with a whitespace from a bashscript to a grads script?
I want to do something like this:
grads -lbxc "run $var_1 $var_2 ... $var_n" but some of the var_x variables looks like "foo bar"

Any ideas?

Best Regards,
Simon
