Parallel is Good Stuff (tm) and works very well but I haven't had much cause to use it. For ad-hoc system modifications I've found myself using tmux's synchronize-panes feature, or xargs. For anything bigger or more involved then I break out Ansible/Chef/Puppet depending on which client project I'm working on. I remember one place I worked at had a huge elaborate configuration/deployment system hand written by the head IT guy which used Parallel+bash+perl extensively. Thing is, while it was a great system, I could make the same changes in Ansible or Puppet with a couple of lines and push them within minutes, while making changes using the hand written system might take hours. Plus no logging and poor error handling led to all sorts of problems with that system, despite it being a real labour of love by that wacky Finnish dude. However this sheet is really nice because it is just one side of a letter/A4 piece of paper and lays out the information clearly. I definitely want to mess around with Parallel now because of this cheat sheet. I wonder how it was typeset or laid out on the page? I try to write my own cheat sheets but they always seem way too sparse with too much white space. Maybe it is written in LaTeX or similar. |
