Using powershell left a really sour taste in my mouth. I felt I was promised that objects and types would prevent errors, but it just feels like everything is harder and mistakes are just as easy.

For example, 'diff (cat a.txt) (cat b.txt)' does something very different from what you'd expect, but works OK for most inputs. The perfect combination for putting bugs into production.

I still like that powershell exists. Especially on Windows where they needed it most. On Linux, though, I'd rather stick with the devil I know.
