gnu parallel in the bash manual
I don't quite see the point of having gnu parallel discussed in the bash reference manual. http://www.gnu.org/software/bash/manual/bashref.html#GNU-Parallel I don't argue that it can be a useful tool, but then you might as well discuss sed awk grep make find etc.. Or even the ones not part of the standard toolset since parallel is not installed by default even on the linux distribution I know: flock fdupes recode convmv rsync etc... On top of that the examples teach incorrect things eg, "the common idioms that operate on lines read from a file"(sic) for x in $(cat list); do doesn't even read lines! I'd say this should be removed.

Actually xargs could do everything listed better. and is installed by
default on most systems.

this is actually more disturbing.
ls | parallel mv {} destdir
find -type f -print0 | xargs -0 -I{} -P /bin/mv {}

Or the examples should at least be fixed. there are terrible practices
being shown there.

Count me also in favour of removal of this section. At best the entire
section needs a complete rewrite, but why on earth we have a whole section
dedicated to a nonstandard external tool is kind of baffling.
