Bash script check if tilde '~' is an argument

Question

I have a simple bash script that can accept arguments that it will be treating as text strings, nothing more.

If I give it ~, without quotes, then the home directory /home/users/me is what's parsed. Quote it, "~", it's fine. The character "~" is what I want, not the home path.

Is there any way I can ensure an un-quoted ~ is treated exactly as the character "~", not the home directory alias?

Answer 1

The bash shell is expanding the ~ on the command line before the argument is passed to your script.

There might be a bash option that you can change in your shell, but that would affect everything in your shell, which doesn't sound like what you want.

The short answer I think is no. There's nothing you can do in your script to change how the parent shell expanded any arguments before passing them to your script.
