Set Operations in Unix Shell

[pkrumins]

Hi all!

I wanted to share a nice article that I wrote about doing various set operations in Unix shell. I used awk, comm, sort, uniq, diff, join, head, tail, and other Unix utilities to do that.

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

I also created a .txt version of the article. It can be downloaded here: setops.txt


What do you think about it?
