Using curl in a bash script and getting curl: (3) Illegal characters found in URL

The $URL contains a \r (CR) at the end (0d). Remove it with


before using it with curl.

I had the same problem, but it was caused by me having created the script through Windows, which meant that the end of line had an unnecessary \r.

A simple dos to unix conversion fixed it.

It could be an enter at the end of the file. Try to remove it or delete it, note that the enter character is not something view-able....
