And it is exactly the hacking part that GNU Parallel tries to help with: A lot of the helper functions in GNU Parallel could be done by expert users (--nice, --tmux, --pipepart, env_parallel, --compress, --fifo, --cat, --transfer, --return, --cleanup, --(n)onall).

But non-expert users will invariably make mistakes (e.g. get quoting wrong, not getting remote jobs to die if the controlling process is killed, or re-scheduling jobs that were killed by --timeout), and why not just have small wrapper scripts built into GNU Parallel that are well-tested, so the non-expert users can enjoy the same stability as the expert users?

Having written my fair share of those hacky wrapper scripts before I discovered GUN parallel I certainly am very happy that they offer everything I need in a single easy to use command.
