Set Operations in Unix Shell

Hi all, again! Smile

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:

I just published another

I just published another detailed post on working efficiently on bash command line, together with a cheat sheet.

The article starts by reviewing the keyboard shortcuts for history retrieval in emacs and vi editing modes, then it covers the commands for listing and erasing the history, then it goes into discussing history expansion mechanism - event designators, word designators and their modifiers. Finally the guide lists variables and options to modify the default history behavior.

At the end of the guide I include a link to downloadable cheat sheets in pdf, plain text ascii and latex formats.

Read my article "The Definitive Guide to Bash History"

4MLinux 20.1 released.

This is a minor maintenance release in the 4MLinux STABLE channel. The release ships with the Linux kernel 4.4.34, which restores PAE support that "magically" disappeared in 4MLinux 20.0 (sorry :-). Additionally, some popular programs (Double Commander, Dropbox, Firefox, Java RE, Opera, PeaZip, Thunderbird, Wine) have been updated, too. Read more

Refracta 8.0 Is a Pint-Sized Powerhouse

Refracta is a somewhat obscure Linux distribution that offers exceptional functionality and stability. Obscurity is not always a bad thing when it comes to Linux distros. You can find some very worthwhile alternatives to your current operating system. Refracta is a big surprise in a small package. Many look-alike desktop distros are difficult to distinguish from run-of-the-mill garden varieties. Others offer new adopters something unique that makes using them fun and productive. Refracta is one of the few full-service Linux distros that makes an easy and more convenient replacement for pocket Linux options such as Puppy Linux. Not all Linux distros that install to a USB drive -- and have the ability to save files and system settings in a persistent mode -- work equally well. Read more
