Description: Learning the power of working from the LINUX command line, combining multi-purpose Bash commands with Perl. Explained by one of the best RedHat perl programmers.(note: I apreciate all the following wise comments, but read the first paragraph of the first article, where he explains that he is going to do some unreadable code, inscrutable code, and disposable code :)

Two articles:

How I learned to stop worrying and love the command line by Chip Turner, part 1 (http://www.redhat.com/magazine/004feb05/features/bash/)

I hope you'll enjoy it as I did.

There are also other articles that might be used as incentive for further reading about oneliners. One is a nice story writen with the Humphrey Bogart films' fashion but about a perl case. Read this Ben Okopnik (a oneliner expert) story: Perl One-Liner of the Month: The Adventure of the Spicy Blonde(http://www.gacetadelinux.com/es/lg/issue96/okopnik.html). There are also newer 'adventures' at the original LG's site (http://www.linuxgazette.com/node/1090) (NOTE: see also this story... http://linuxgazette.net/issue89/okopnik.html to round all up)
