terminal
I mean change $HOME not by defining in ~/.bash_profile, but loading the variable when shell opens.
By the way, after some misoperation I cannot even get into the Terminal now… It now says [Process completed] and does not respond, as it should when every time it exits. Is there a way to configure or re-install the Terminal?
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.
An unexpected error occurred (error code -50).
You can change this in Terminal's Preferences:

I think the reason your terminal is acting up is that the default command has been changed somehow.
In preferences->Startup see what is set
I suspect that the Command is running something other than a shell. Change it back to Default login shell and all will be fine.
