import improvements from GPUJPEG - summary: - LABEL - replace ' ' with %20 (will get to URL) - use while instead of for..seq - cat json file directly (avoid interpretting \n and \r that XSI-compilant echo, as in dash, does) - cat really the $json file, don't print its name - wrap long lines + early return in while-loop The rewrite of `for n in \`seq` may be perhaps a bit controversal (with while is less readable) but technically POSIX doesn't specify the seq comand.
