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?
