  sponge is cool. But on debian/ubuntu, it's packaged up in moreutils, which includes a few helpful tools. However a programme called parallel is in moreutils, and that's not as powerful as GNU's parallel. So I often end up uninstalling sponge/moreutils. :(

    There's some attempt underway to fix that fwiw: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=749355 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=749355

    GNU Parallel is an indispensable heavy lifter on the command line. I was expecting it to show up in the article.

    moreutils for my usage contains 'chronic', which prepended to a command, stops cron from alerting on any non-error output. Big fan.

  Thanks for throwing this out there. Never heard of this command before! Definitely a good one for my bag o' tricks.
