Many years ago (30?), the Plan 9 shell, rc, was made available for other platforms. I was working at the Big Nerd Ranch and ran it everywhere I could (I was doing 2nd/3rd level support work that gave me unfettered privileged access almost everywhere), until the nascent in-house software release process (SRP) caught up and sudo started becoming more widespread and privileged access started getting locked down.
At that point, I needed muscle memory across all machines more than anything else, and switched back to sh (bash was still very new and not widely available, csh was born borked, and ksh was only available under certain OSes). That was sad.
rc had a beautiful, clean C-like syntax without any csh weirdness and was much more powerful than sh. Scripts were a joy to write and maintain.
