The big problem with Powershell, and it makes it borderline unusable on Linux, is its crazy error handling. The equivalent of bash's `set -e` is `$ErrorActionPreference="Stop"`.

The problem is that it treats any output to stderr as an error and ignores actual posix errors (non-zero exit codes.) What's worse is in some contexts the error it throws on stderr is impossible to catch.

I really love Powershell in a lot of ways but this makes a lot of really basic scripts in bash very cumbersome to write in Powershell.
