tldr; you should probably git
Since I started using git and now GitHub in September, I have to say it is quite life changing. I’ve created a few repositories that I use for some configuration items and I found that it really allows me to tinker with my system and other things much easier. Previously I used to have countless tabs open in gedit/geany and struggle to keep whatever I was breaking in some sort of order. Now I can check out whatever I’m working on, break it, discard the changes and I’m back to a known state or if by some stroke of luck I get expected results, I check it in and commit. While I can’t manage to find the time to read Pro Git – its on the to do list, I’m having a blast learning git the hard way. Also, I should point out that git-cola is really helpful as it allows me to visualize my changes (I love it for repos that are not pushed to GitHub) which is perfect for the way I work.
