I've read around and the command is,
convert -crop 32x32 terrain.png tiles/tile%03d.png
but no one ever mentions where to put the command, I've installed imagemagick and I run imagemagick display but there is no place for commands.

IM is primarily a command line driven system. You simply type the command in a terminal window or if using PHP, you can put the command line in an exec() call from PHP. You do not display the image first and work from the X display GUI for IM.
Syntax should be (assuming your terain.png is in the current directory from which you run the command and that tiles/ is a subdirectory of the current directory)
convert terrain.png -crop 32x32 tiles/tile%03d.png
However if you do not need to save the virtual canvas, add +repage after the crop 32x32.
