This will give you the viewpoint of a user who cannot just 'get out of jail', and you will find that the simplest way of doing admin work is to open a terminal as root, or sudo to a text editor and/or file manager such as mc. It is quite difficult doing admin work from an unprivileged GUI login. After a while, you will find which jobs can be most easily done with the command line, and which are actually easier with the GUI. Don't choose the more difficult way of doing things just because it is 'right'. On the other hand, learning computer science requires discipline, don't try to engineer a situation where discipline is not necessary. Learn to ignore the GUI, even though it is there and it is tempting you. I say this because I always use a workstation unprivileged, and do all admin in a terminal. I like mc, but there is nothing stopping you using vim, vi, or whatever, along with cd, cp etc. Don't forget to learn at least the basics of mutt for email, and lynx/links/elinks for text-based web browsing. I do also run a server without X, and use mc over ssh for all admin work, and sometimes mutt is the simplest way of moving data around. Learn wget and/or curl for text-based downloading. Don't confuse command line use with knowledge of Linux. It's necessary, but not sufficient. The various window managers, desktop environments and so on are a significant part of a real-world Linux workstation installation, but what you need to know about is how to configure these environments, and fix them when they break, not just how to use them. Try the lightweight desktops, LXDE and Xfce, as well as a few bare window managers. A display manager from an environment, such as gdm or kdm, will allow a choice of startup environments from whatever is installed. This will give you a feel for which parts of Linux are dependent on the desktop environment, and which underlying parts remain the same in all environments. Microsoft has always tried to give the impression that what you see on your monitor *is* Windows, which isn't true, and it is even less true of Linux. You might also look at Linux From Scratch, which doesn't teach you http://www.linuxfromscratch.org/lfs/ everything there is to know about Linux, but does give you a good idea of what is actually necessary to boot Linux and how to build software independently of a package manager. It's all easy and soft these days, I did a couple of installations several years ago, before the automatic systems, when you really had to compile everything manually, some of it twice. I did actually borrow one of the LFS daemon scripts to create an iptables pseudo-daemon long before it was available off the shelf elsewhere. Learn iptables... If you're dead set on multiple Linux versions with some shared directories, and I always leave a spare partition for a small single-partition emergency installation, then make sure you know about uids and gids, and how to ensure you have the same identity on both/all installations. And when you think you know a bit about Linux, make an installation of Debian unstable (sid) and use it as much as possible. It's not as terrible as some people say, but you really need to be willing to learn if you use it as a main OS. In the last month, the LXDE environment broke quite seriously, and remained that way for a few weeks. You will want to know how to work around something like that. When you've got the hang of unstable, you can start writing scripts in bash, perl or python... -- Joe -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
