| 3791 | The Kernel, Shells and Daemons. Greek Gods in computing
The Greek Gods didn't like washing up or ironing. So they employed mortals to to it. Problem was that those mortals didn't last for ever, and sometimes went on strike over one thing and another. So The Gods did a deal with some of the current batch of mortals, and it went like this: "We will make you ... | 2012-07-14

| 1527 | Selecting file names in a shell - one word or another
If you want to select all file names that include the words "cat" or "dog" in them with file name matching, you can do so using curly braces - that's supported by most modern shells as part of what is known as "globbing".

| 1345 | Perl and Shell coding standards / costs of an IT project
There are three major staff costs in the life of an IT project - the specification and development of the system, the maintainance and upgrading of the system though its life, and the investment that's made in data entry and integrity through the life of the system.

| 1287 | Work and play at Well House Manor - Football and Shell Shortcuts
We're running a Linux and LAMP course this week - great group and I'm going to be sorry when it's the end of the course.
Yesterday we had a cold buffet lunch for a change, and made the best of the lovely weather and spacious garden to relax for a while - we do a long day, and so a good break at lunch ... | 2007-08-01

| 827 | No news is good news with Unix and Linux
No news is good news ... so says Linux and Unix. All processes return a status code, and you can expect that to be:
0 - success
1 - failure
2 - abject failure

| 749 | Cottage industry or production line data handling methods
If you're running a cottage industry, for efficiency's sake you'll run the first process on each of your raw components first, and store the partially-completed elements in a basket as they're processed. When you've completed that first process, you'll then apply the second process to each element ... | 2006-06-07

| 64 | Shell Script for CGI on the web
In the course of duty (providing simple "how-to" examples), I've come up with a short shell script in the Bourne again shell that allows a rudimentary lookup in a data file on a server running CGI. Nothing special about this, except it's a short example.
Run it from this link and try putting in data ... | 2006-06-05
