      If it's still the same as in your post above, it can't work unless you fill the variables with content. 🧐

          Your script has Windows (DOS) line endings, make sure you edit the script with an editor that understands Unix line endings and set your editor to save your script correctly. When in doubt, use Notepad++.

            Or you could do it in Retropie's command line:

            sed -i 's/\r$//' root.sh
            

            or

            sudo apt install dos2unix  # only needed once to install dos2unix
            dos2unix root.sh
            

            Both edit the file in place, so be sure to have a backup if anything goes wrong.

                @Clyde the first solution it's for convert my script to unix script ? Good to know. I'll try this, but for my next script i would like to make them in unix language ;)

                  Both are. The first doesn't require the installation of another tool, as sed is party of most Linux base installations; the second may be more easy to remember as something like 's/\r$//'. ;)

                      @wsamael Your error message said:

                      '\r': command not found
                      

                      Windows ends a line in a text file with a carriage return (\r) and a line feed (\n), wheras unixoid systems only use \n. Thus Retropie's command shell bash rejected the \r in your file as an unknown command.
