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.txt) for ...

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?

I'm running a script to create a 2px by 2px png file for each of the possible 16.7 million colors available in the hex color spectrum. Here's the script: #! /usr/bin/sh list=$(cat newhexcodes.txt) for color in $list; do convert -size 2x2 xc:"#$color" $color.png done newhexcodes.txt contains a list ...

Figured it out: IM is happily cranking away...

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 ...

Snibgo, the command you showed also worked for me. I think that the list isn't being passed correctly to the script. Anybody see anything?

I think there is supposed to be an array created that points the name and color to the values in the lookup list. This is actually code lifted from this page: http://www.starrhorne.com/2012/01/18/making-a-million-little-color-swatches-with-imagemagick-and-rake.html I emailed the author but decided ...

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" %x ...
