Hello robertkwild,

What input do you use and what errors do you get?

You might be hitting a number of problems because you have minimal error checking and your mv command might have a null input so becomes invalid too. This might not be a problem for a simple helper script for yourself but might be more confusing if you delegate it.

Is a null response to the source directory okay? That would change to the user's home directory.
