ipython shell is great for quick jobs, and is taking over a lot of what I used to do with long pipelines of cut/grep/perl -n, etc. Being able to grab some filenames/contents with foo = !ls bar = !cat *.txt # returns list of lines is super handy. And the real shell is always just C-z away, if I need it.
