I put a few more Linux articles live yesterday.
- Installing Software Packages (rpm, yum)
- Linux Process Management (ps, top, renice, kill)
- Linux Run Levels, Boot, Reboot, Shutdown
- Linux Redirection and File Processing
- Linux Groups and Users
- Linux Files, Directories and Permissions
As before, they are targeted at the level of information needed for the RHCSA exam, so nothing really new for long time users of Linux.
I also changed the introductory article to include the exam objectives, each linking to the relevant article for that objective. I didn’t want to break things down to one article per objective, because I think there is too much crossover, so this seemed the best solution.
Writing this basic Linux stuff can be a little dull compared to writing about new Oracle features. Sometimes I feel like writing, “just read the bloody ‘man/info’ page!” I considered giving up a couple of times, then I got a rash of simple Linux questions and it seemed like destiny when I could easily answer them by pointing to an article I was currently writing. I guess in the past I’ve been a little dismissive of these types of questions. It’s easy to forget that Linux is still very new to lots of people. I tend to think of Oracle DBAs as having a reasonable UNIX background, but there are a lot of Oracle DBA types who never venture far from Windows, so maybe this stuff is more useful than it seems at first sight.
I guess I’m about two thirds of the way through the RHCSA notes now.
