I think most people would be shocked to know how much glue code is in powershell or bash/perl that kind of keeps everything running.

I remember looking on in horror as a QA person who was responsible for the install/deploy of some banking software scrolled through the bash/perl script that installed this thing. I think it had to be 20k+ lines of the gnarliest code I've ever seen. I was the java/.net integration guy who worked with larger customers to integrate systems.

My group insisted we should do single sign in in perl script but I couldn't get the CPAN package working. I had a prototype in java done in an afternoon. I never understood why people loved perl so much. Same with powershell. Shell scripters are a different breed.
