I installed MIT/GNU scheme and am trying to add the directory to my $PATH variable so that I can run it from Terminal.

The app name MIT:GNU Scheme.app is a veritable "perfect storm" (for path names) as it includes a colon and a space.

I've tried adding each of the following to my ~/.bash_profile, none have worked:

export PATH=$PATH:"/other/paths:/Applications/MIT\:GNU\ Scheme.app/Contents/Resources"
export PATH=$PATH:"/other/paths:/Applications/MIT\:GNU Scheme.app/Contents/Resources"
export PATH=${PATH}:"/other/paths:/Applications/MIT\:GNU\ Scheme.app/Contents/Resources"
export PATH=${PATH}:"/other/paths:/Applications/MIT\:GNU Scheme.app/Contents/Resources"

It won't work. You have several options:

  1. Create an alias for bash to run the command.
  2. Create a symbolic link to the executable from a directory in your PATH. (I like to have a directory ~/bin at the front of my path for such things.)
  3. Create a symbolic link to /Applications/MIT\:GNU\ Scheme.app/Contents/Resources somewhere and put the link in your PATH.
  4. Rename the application.
  • Creating an alias worked, thanks. A symbolic link to the directory didn't for some reason, something specific to the app, I suppose. Is it OK to just rename a .app and have everything work as it should?

  • I am not sure if just renaming the app will work. Perhaps you need to change the value of CFBundleDisplayName inside Contents/Info.plist as well. Jun 6, 2012 at 14:48
  • I'll stick with the alias, was just curious whether that was allowed.
