None of those are more crucial to my workflow. You are generalizing in dangerous territory. Bash is as useful and powerful a tool as Illustrator, Autocad, Maya etc.
The point is, anyone telling me Bash is dangerous is afraid. That is what I was responding to, someone saying ls and cd were dangerous commands. Context.
Oh that's of course incorrect. Bash is as dangerous as Finder as long as you don't use sudo, imho.
And yes I'm generalizing, because as far as I know, Apple's biggest demographic is working professionals in those specific industries, and for them learning more on the apps they work on will be much more important than learning bash.
