PowerShell
How have I not realised just how useful this is until now? Anything that - in a dos shell - allows you to parse a file and pull out a specific word of a specific line of a specific file is surprisingly useful.
And I suspect that - even with that - I have just scratched the surface of what it can do.
I have always been a big fan of dos batch files -- for writing quick, dirty, useful programs to do something they can’t be beaten -- but I think I might now shift my allegiances slightly :)
