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:

What do you think about it?

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"

Red Hat Virtualization 4

  • Red Hat’s gunning for VMware with virtualization platform update
    Open-source Linux vendor Red Hat Inc. has thrown in support for OpenStack Neutron and other new technologies with the latest release of its software virtualization package, in what looks like a bid to steal customers away from VMware Inc.’s more widely-used solution. Targeted at convergence, Red Hat Virtualization 4 is the first version of the platform that doesn’t include the word “enterprise,” in a move that suggests the company is hoping its virtualized stack will become the platform for convergence, rather than a server density product. OpenStack Neutron is the open-source networking project used by Software-Defined Networks (SDNs), which up until now has only been available as a preview. Many have criticized Neutron’s development for lagging behind the rest of OpenStack’s code base, and Red Hat was one of several vendors to concede that things could be sped up a bit. With the inclusion of the software in Red Hat Virtualization, the company says its Linux platform can be used to run both cloud-enabled and “traditional” workloads in concert.
  • Red Hat Virtualization 4 woos VMware faithful
    It's easy for a virtual machine user to feel left out these days, what with containers dominating the discussion of how to run applications at scale. But take heart, VM fans: Red Hat hasn't forgotten about you. RHV (Red Hat Virtualization) 4.0, released today, refreshes Red Hat's open source virtualization platform with new technologies from the rest of Red Hat's product line. It's a twofold strategy to consolidate Red Hat's virtualization efforts across its various products and to ramp up the company's intention to woo VMware customers.

NOAA Breaks Weather Apps, Slackware Updates, Valve @ 20

The LinuxCon headlines continue to dominate but, more importantly, our desktop weather apps are broken thanks to NOAA decommissioning the site. Liam Dawe looked back at 20 years of Valve and Sebastian "sebas" Kügler introduced new KDE kscreen-doctor. Slackware rolled out some updates including a rare kernel upgrade and The VAR Guy wants to hear about your first time. Read more
