Comment Well, perl and vim yes, but not for that reason (Score 1) 359
I use VI and VIM as my editor because as a system administrator, VI was one of 2 editors that were guaranteed to be in Solaris should the system be in a real bad state and in recovery modes. I use perl because it is installed on everything out of the box (Solaris, Red Hat, SUSE, and IRIX all of which I deal with). Python isn't on all those OS's by default (Solaris in particular), which means it might not be on all the systems I deal with. I'm not about to go and write code that I can't run universally on the systems I deal with.
