In my personal life I am a Linux-onlyist. But Windows pays my bills so...
When I moved into my current job automating sysadmin work for an enterprise I discovered the joy of PowerShell and an analysis of my enterprise Bitbucket account shows that I have committed more LoC of PS than any other language.
PS is a joy to code in and would rather write programs in PS. But I still would prefer BASH for oneliners and CLI use.
