Senior Operations Analyst -- Knowledge of scripting languages (Korn Shell, Perl and/or Python) Korn shell surprises me! I thought that Google was always a Linux shop, and never used any other Unix. Was Korn shell ever popular on Linux, as opposed to bash? I didn't use shell back in 1999, but I thought that bash was already popular back then. bash was apparently the first program that Linus Torvalds got running on Linux, back in the early 90's. I saw a bit of early Perl at Google when I worked there, but it was mostly all Python. I never saw any Korn shell, although I guess bash is compatible with Korn shell, so maybe that's what they meant. Or it was written by a recruiter who copied from other common job postings at the time.
