Given the following command line:

'/usr/bin/gm' convert 'directory/filename.psd[0]' filename.jpg

I will always receive all layers from the .psd as output:

$ ls something*
something.jpg.0  something.jpg.1  something.jpg.2

The documentation clearly states:

Use a square-bracket syntax to indicate which frame or frames you want. For example,

gm convert "Image.gif[0]" first.gif
Will extract the first image (scene 0) from a GIF animation. Be sure to surround the file specification with quotation marks, to prevent the shell from interpreting the square brackets.

I tried messing around with it in many ways, but I always end up with the same result.

It sounds like you need to flatten the PSD to a single layer. I would try adding the -flatten flag to your line. This may convert all of the layers to one JPG instead of multiple files.

Also, it looks like by adding the [0] you're telling it to loop through the layers as it would the sequence of images in a gif file.

While that might work (and I will be thankful if it does), why doesn't my approach work? It seems like I use it exactly as described in the documentation. –  Oliver Salzburg Mar 8 '12 at 23:08
    
Because by adding the [0], it looks like a "command" to loop through the possible images/layers in the specified file to export several files based on that information. That may be very useful to some, but counterproductive to others. –  kobaltz Mar 8 '12 at 23:11
    
The main problem, I believe is that your documentation is to split an Animated GIF image into several files. Almost like taking a movie and making several images from each frame of the movie. –  kobaltz Mar 8 '12 at 23:11
    
What kind of makes me doubt this, is the fact if I use ImageMagicks convert for the same purpose, it outputs a single file when using [0] and multiple files when not providing [0]. –  Oliver Salzburg Mar 8 '12 at 23:15
