Hi all, again!

I just published another article that comes with a cheat sheet.
In this article I implemented various set operations by using awk, comm, sort, uniq, diff, join, head, tail, and other Unix utilities.

The article explains 14 various set operations:

• Set Membership.
• Set Equality.
• Set Cardinality.
• Subset Test.
• Set Union.
• Set Intersection.
• Set Complement.
• Set Symmetric Difference.
• Power Set.
• Set Cartesian Product.
• Disjoint Set Test.
• Empty Set Test.
• Minimum.
• Maximum.

The article can be read here: Set Operations in Unix Shell

And the cheat sheets can be downloaded here:
* ASCII .txt format: setops.txt
* PDF format (.pdf): setops.pdf

What do you think about it?
