This is just a small curated collection from myself and old friends — mainly rails devops. I'd be interested in hearing from other rails devs/ops what you use on the command line on a daily basis, what cool thing you know about that no one else does, etc! I'll be adding more as we go....
Sorry about that! I didn't submit the link otherwise I would have mentioned it.
Though...the only way it's really "rails focused" is that the commands are collected over time and sourced from my fellow rails developer/sysadmins. A lot of these are basic/general linux commands.
