Here's one I was thinking of: https://github.com/gdm85/coshell

The comment about motivation came from a bug report about parallel being "chatty": https://github.com/Homebrew/legacy-homebrew/issues/29060

Nothing homebrew can do about it, of course, but this illustrates one of the implications of parallel doing something unexpected; package managers have to field the complaints.

> Return value will be the sum of exit values of each command.

That's unforuntate design choice.

Exit status is 8-bit only, and some programs exit with high numbers¹, so the sum could overflow easily.

¹ For example, when a Perl program dies, exit status is 255.

Someone has compiled a big list of alternatives: https://www.gnu.org/software/parallel/parallel_alternatives....

Most of the tools look unmaintained (last release over a year ago).

I’ll look again later today. I tried to find one I saw earlier quickly when I replied above, but I didn’t see it. I think it was also called “parallel” and it mentioned the citation being a factor.
