1. Works even under the most spartan conditions (in a simple remote shell window such as xterm, putty), with syntax highlighting, function folding, tabs, buffers, and all that lightning fast
2. Delete lines matching pattern: g/pattern/d
3. Delete lines not matching pattern: g!/pattern/d
4. Sort buffer: :%sort
5. Filter buffer through command :%!sort -u
6. Delete from current line until end of file (try with a large file!)
7. Increment numeric values: C-a, C-x
8. Complete line pattern C-x C-l
9. Convert a DOS file (with CRLF line endings) to UNIX: :set ff=unix (and then save it)

Quirks

• Sort by movie_year ignored. Works if I specify twice, though looks stupid.
