My company mandates Windows but Git Bash has been a backdoor into Unix tools and I've recently learned sed and awk to take full advantage of it. You need to think a bit about your one liners and they'll always feel very hacky, but sed/awk (with a bit of sort thrown in) are an amazingly powerful combination for dealing with all sorts of messy data dumps. In 10 minutes I can craft a one liner that replaces a 2 hours C# console app and runs just as fast. And, surprisingly, I often find it easier to go back months later and understand the messy looking one liner than the nicely formatted, well commented, unit tested console app.
