    Hi all!

    I wanted to share a nice article/tutorial 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?
