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"

V2 Of KDBUS Published For Linux Kernel Review

The second revision to the Linux kernel based D-Bus implementation is now available for review. Greg Kroah-Hartman on Thursday night posted the "v2" revision of the KDBUS implementation for providing the kernel with a new IPC implementation that resembles the existing user-space D-Bus daemon while adding extra features. Among the changes in this revision to KDBUS are exposing its control files and other information via a new kdbusfs file-system, KDBUS expects to be mounted to /sys/fs/kdbus, a new KDBUS domain is created for each time kdbusfs is mounted, and various other low-level changes. More details via the patch-set series. It's not clear yet whether KDBUS will be ready for merging in the Linux 3.19 kernel or will be held off until Linux 3.20 or longer. Read more
