Change the default action to open executable files in the editor instead of Terminal

When double clicking an executable file (without a file extension) in Finder, it opens in Terminal by default. I can change that to any other application for this single file, but I cannot change the default for all files.

Is there any way to do that?
I never want to open executable files in Terminal, and I'm missing that functionality since NeXTStep, which had a hidden default for that.


Run plutil -convert xml1 ~/Library/Preferences/com.apple.launchservices.plist and add an entry like this under LSHandlers:

<dict>
    <key>LSHandlerContentType</key>
    <string>public.unix-executable</string>
    <key>LSHandlerRoleAll</key>
    <string>com.macromates.textmate</string>
</dict>

You can also change the default application for normal files with no extension:

<dict>
    <key>LSHandlerContentType</key>
    <string>public.plain-text</string>
    <key>LSHandlerRoleAll</key>
    <string>com.macromates.textmate</string>
</dict>

You can apply the changes by restarting. Just logging out and back in doesn't seem to work. You could also rebuild the Launch Services database, but it has the side-effect that the warnings about opening applications for the first time are shown again.

Another option is to add something like this to a duti configuration file:

com.macromates.textmate public.unix-executable all
com.macromates.textmate public.plain-text all

To make this question more searchable, here is the error message Finder shows when you try to change the default application for executable scripts:

The operation can’t be completed.
