In the terminal/ and ide/ directories are the default scripts for the finderButtons apps which can open various IDEs and terminals.

To change which script is run when you press a button, modify terminal.sh or ide.sh. Simply change the path of the script to execute (mind the file type).

You can use any of the provided scripts, add your own scripts to this directory, or use scripts from elsewhere on your machine. Just make sure they are executable.

chmod +x <script_name>
