Good: [-_.a-zA-Z0-9/] Bad: [+,=] Ugly: ["'#!%@: ] scp and crontab don't like the ugly ones but those characters are of cource fully legal to use. If I saw someone using "ugly" I would ask them if it is really necessary. As "ugly" is "bad practice" I would throw --unsafe after an apprentice. At least a warning is recommended. GNU Parallel is quite good at handling quotation so a space character should not be a problem. There could be a bug so don't go near the edge. And DOS don't like the "bad" ones but who cares? Decent citizens is only using the "good" ones and one one have ever got fired for using them. -- ./hans
