Don't use CRLF and add shebang on .sh files

[ghost]

Shellscripts should use default linux line endings, which is LF, not CRLF. Also they should include #!/bin/sh shebang in the first line.

It's probably safer to launch them explicitly with sh filename.sh. That way we minimize the number of files with executable permissions. And I'm using Windows.

I don't think adding the shebang will hurt, especially since it's not related to being executable or not. For the reference: Your scale.sh is executable while both to*.sh are not.

Also sh might accept CRLF on Windows, it will most likely accept LF as well, which is the correct line termination for unix shells (even when not run in a *nix environment).
