Tools - Support GNU Parallel

[BenB196]

Hi, pretty neat set of scripts this project has.

One thing I've noticed is that on relatively large directories with a large number of files, these scripts can occasionally take a good amount of time.

It would be nice if the scripts could leverage GNU Parallel to be able to process multiple files at once.

Taking a script like:

[OK]  All files are UTF-8 encoded.
$ find . -type f    -print0 | xargs -0 -P 2 -n1 grep -Il '' | tr '\n' '\0' | xargs -0 -P 2 -n1  sh -c 'if [ -f "${1}" ]; then awk "/^\xEF\xBB\xBF/ {print FILENAME} {nextfile}" "$1" || true; fi' --

To:

[OK]  All files are UTF-8 encoded.
$ find . -type f    -print0 | parallel 'xargs -0 -P 2 -n1 grep -Il \'\' | tr \'\n\' \'\0\' | xargs -0 -P 2 -n1  sh -c \'if [ -f "${1}" ]; then awk "/^\xEF\xBB\xBF/ {print FILENAME} {nextfile}" "$1" || true; fi\' --'

I don't fully know if this has been something that has been considered, but just a nice thought.
