Thank you very much. That worked perfectly.

Getting this error:

png-blast.sh: line 2: syntax error near unexpected token `"MAGICK_TMPDIR=/home/smcgown/PNGS"'
png-blast.sh: line 2: `putenv("MAGICK_TMPDIR=/home/smcgown/PNGS");'


The script currently reads:
#! /usr/bin/sh
putenv("MAGICK_TMPDIR=/home/smcgown/PNGS");
list=$(cat newhexcodes ...

Thanks for the quick reply! I saw that it's possible to do this with:
Do I use this in a general terminal session or do I need to declare this in the script itself?

Is there bash script I can put in there to do this? I don't know Ruby either so I'm using my basic programming knowledge to ...

Hello all,

I'm trying to create around 900 small files from a list of hex codes. I have a YAML file (hexcode.yml) and am using the following code:

#!/usr/bin/ruby
require "yaml"

YAML.load_file("hexcode.yml").each do |name, color|
p "Creating: #{name} (#{color}) => images/colors/#{name}.png ...
