That is "implementation dependent", and not a rule. 'sh' may take additional parameters after '-c'. In the case of Linux which uses `bash` for `sh` this can be helpful since when bash is envoked with ths '-c' argument, $0 becomes the next parameter, instead if the file-name, and $1 becomes the second, etc.
