From time to time everybody uses shell commands to work with data
stored in files.
cat, grep, cut, tr, comm etc. helps to deal with that.
Last month I was crawling lots of data across the web. Later on I had to
split data by some delimiter and make some set-like operations: UNION,
INTERSECTION etc. Obviously I did. But it hurt a bit. There is still no
tool to treat files like sets. Ofcourse I may use sort of utils and
combine them, but in more complex cases I would like to use something
dedicated. For example look at this:
http://unix.stackexchange.com/questions/11343/linux-tools-to-treat-files-as-sets-and-perform-set-operations-on-them
- few simple operations and there are lots of ideas. But what if I would
like to (X+Y)*Z and not to create temporary files ?
My Idea is about set utils; a set of utilities to deal with sets or
maybe one utility to 'rule them all'.
How about it ?
