Almost like old times

It felt almost like old times yesterday - now that we're doing a LAMP deployment course (with the "L" standing for Linux if anyone's new to that term), customers have started to ask for the on site Linux element tailored / with a few additions. I found myself writing new material to cover Linux Utilities and Shell Programming and it was great fun - I think the saying is "water off a duck's back".

Linux has a huge array of useful utilities that are sometimes under-rated; what better way to filter out records on a one-off basis or to script some operating system issue? I started training on the Unix equivalents some 10 to 12 years ago, and although I've been standing up in front of classes teaching languages such as Perl and Java in more recent times, I always have a fondness for grep. It'll be good to overview them occasionally again, and it was a pleasure to write and put the utilities, shell programming and languages like Perl each in context with one another in our own new notes.
