Ubuntu is a growing favorite for the desktop, Debian is one of the favorites for servers. The version of the distribution is also important when looking for tutorials, but not nearly as much as the distribution. Most distributions have a website, such as Uvuntu.org that has fairly good documentation, including reference manuals and tutorials. If you read any reference manuals, make sure they are for the version that you are using. I think most of the Linux distributions use the bash environment. There is plenty of reference style help through commands like 'man' and 'info'. So to look up all of the possible options for the 'apt-get' command, type "man apt-get". For bash script programming, after looking through the official documentation mentioned above, I just perform a Google search for something specific after "ubuntu bash", or whatever environment in which you are interested. Don't be sure that you will not be expected to touch Apache. I would assume this web server needs security updates at least as often as the SQL database software.

I have just been informed that we are switching all our HP/UX environments over to Suse linux. While I have been asured that I can continue to use Tera Term for my SSH sessions, I know there are going to be some differences between the KSH shell I am used to and whatever shell linux is using. So, I will be jumping into some linux book or books myself shortly. We use Weblogic instead of Apache but still I need to learn how to manage the Weblogic environment under linuyx right away. So, while I don't as yet have any suggestions, I will certainly be following this thread closely. ----- Original Message ----- From: Homme, James<mailto:james.homme@xxxxxxxxxxxx> To: programmingblind@xxxxxxxxxxxxx<mailto:programmingblind@xxxxxxxxxxxxx> Sent: Wednesday, July 28, 2010 7:36 AM Subject: Learning What I Need To Know About Basic Linux Hi, On the system I'm using, I don't have the authority to administrate the operating system, but I do have the authority, and need to, administrate the other software on the box that doesn't come with it, so I need to come up to speed yesterday. You know how that is. I cracked open the book called Learning The Unix Operating System Fifth Edition and started using it to learn basic commands. Among other things, two things are tripping me up. First, I'm using Putty. I have it set up properly with JAWS, but I'm being driven crazy any time data needs to scroll the screen because the whole screen is being spoken. The second thing has to do with knowing what I need to learn. I'm just trying to learn what I need to know for now, and branching out from there. Unfortunately, I'm not sure exactly what all that entales. But fortunately, I do have some time, because we're just starting to use MySQL and PHP. So I see three big tasks or things to learn. * What's involved in administrating Apache, like not letting the logs get too big, possibly installing a friendly statistics package, or whatever. * Setting up daily backups of the changed MySQL database or databases that we have. * Whatever MySQL administration that I have no earthly idea I may need to do. * I'll have to upgrade MySQL at some point. * I'll have to upgrade PHP at some point. * I pray that I never have to upgrade Apache. * Possibly installing some nice, convenient packages like PHPMyAdmin. But I'm thinking that like the people who were advocating learning the dirty way, I think it's best to probably learn how to do it from command lines so that I have total control and really know what's going on. But I'm starting with basic commands, but at the same time, trying to do my first Drupal installation, and I'm in real trouble because of course there's this deadline. Back to my UNIX book. Specifically, I didn't see in the book two things. First, what permissions do files and directories automatically get when you create them? Second, I used to know a little more about some sort of file in my home directory that I could put stuff in to customize the environment a little more. I know that that file has a name that starts with a period. Yet another thing. I'm pretty sure that the shell I'm using is called the bash shell, but I don't know how to find out. And how does that affect how I work with the system? For example, if there's another shell that's better, what is it, what does better mean, and how to I turn it on. Like I was thinking of making aliases for cp and rm that automatically run the -i option to keep myself from trashing stuff. Someone please hold my hand and tell me it'll be all right. <grin> Jim Jim Homme, Usability Services, Phone: 412-544-1810.
