Execute a BASH script... by double-clicking on it? Is it possible to execute a bash script by double-clicking on it? The shell script executes with $ ./script.sh without issues.  Double-clicking the script opens TextEdit. It would be nice to execute by clicking on it...

Maybe change the extension name to .command, but I think there should be some workaround to make .sh work.

To run by double click on the icon:
open terminal and cd to directory of script.
then chmod +x .
finder will decide if it is excutable or not.
