>performance performance UN*X does not have anything that makes it inherently performant in contrast to a sanely designed OS with one language instead of 10 that all do the same thing, a terminal emulator which is by design non performant, and a bunch of text formats that are also non performant and have bad semantics > These small tools, with little preparation (The AWK programming language, man ksh, "perldoc perlintro"...) can do in days what for the programmers of non-Unix OSs took weeks of clumsy Python hacking. no, it really can't. if you are string flinging on such a high level, your code is broken to hell. the reason perl awk bash sed suck so much is that they are intrinsically insecure the moment any input anywhere can be controlled by an adversary (and just wonky and gets in the user's way without even talking about security). working around that requires extreme levels of discipline that go far beyond programming in a real general purpose programming language (java, C#, ML, Pascla, Ada, etc). the moment you are able to write a secure *sh program, you are spending 3x as much time per line of code than in a real language.
