Gary Bernhardt did a screencast showing an example of this kind of Unix hacking: http://blog.extracheese.org/2010/04/a-raw-view-into-my-unix-... He always impresses me with how quickly he moves from one thing to the next. It's a beautiful thing to watch, to me.
Generally good stuff, but my personal taste for the command-line stuff would run more towards awk -- it's lighter weight and easier to pick up than full-blown perl.
On the other hand, if you're going to do a lot of this stuff it's worth tracking down a copy of "Data Munging with Perl" by David Cross ( http://www.manning.com/cross/ ) which, while slightly out of date (it covers classic Perl 5 OOP, not New Perl) gives a solid grounding in how to do almost all of this stuff entirely within Perl.
If this is appealing, I recommend trying RecordStreams (http://code.google.com/p/recordstream/). I use it for ad hoc Big Data command line analysis almost daily.
