That's how i feel about "convert" from imagemagick
And "import"!
Hate it when I'm starting a newly written python script, and have forgotten the hashbang. For some reason my mouse cursor turns into a cross, and the script does nothing!
Always takes me a couple of seconds to realize what's going on...
I have a similar issue where I tend to start typing python code in the shell without remembering to enter the repl first.
Which is why I use graphicsmagick [1] instead. The imagamagick executables becomes options behind the 'gm' executable.
