Goodbye Woody, Welcome Etch //at 00:53 //by abe

It finally happened. I installed Debian Etch on my last Woody box, a 400 MHz Pentium II with 576 MB RAM named gsa which is my home desktop since I bought it at LinuxTag 2003 in Karlsruhe.

And no I didn’t do a dist-upgrade, neither direct no via Sarge. As already planned I removed some no more necessary operating systems from that box and installed Etch on the freed disk space. Woody is still installed on that box in parallel and was recognized perfectly by Etch’s installer.

I took a few hours but also was big fun to go through Etch package list and to decide what to install. Overall the installation of 5 GB of software took about half a day.

In general everything went fine, the only thing I’m yet missing is sound. Etch didn’t seem to recognize my soundcard at all although it’s a well-known brand and defacto standard for many other soundcards: a Creative Labs Soundblaster. Well, the 16-Bit ISA version, needing the full length of the slot. Worked fine under Woody. Well, I hope I’ll get it working again manually.

What on the other hand is really nice with udev hell —eh— hal and all those new automatic bells and whistles: The desktop (well, at least GNOME Nautilus as well as XFCE, but probably also KDE) recognises when I insert a 3.5” floppy into the drive and shows me a nice floppy icon on the desktop. You think, that’s impossible? Floppy drives don’t inform the rest of the system when a floppy has been inserted without you polling the drive every few seconds? Well, USB floppy drives can. And they do. :-)

I still need time to migrate all the old settings from Woody to Etch. I’ll probably stick with FVWM, but perhaps will use the GNOME enabled version. What’s already done is the migration from tcsh to zsh. On all new or dist-upgraded systems after Etch I’ve chosen zsh so with my last Woody installation retiring I’ve also fully migrated to zsh.

So I’ve got now most of my active private boxes running Etch. Only the noone.org web and mail server “sym” (an amd64 box) as well as my 133 MHz ThinkPad “bijou” are still running Sarge, both with 2.6 kernels.

So with switching to Etch on gsa, I also got no more Debian box running a 2.4 kernel. The only 2.4 kernel I run is on my FreeWRT WLAN router named pluriel, which runs 2.4.33.3. But I expect that 2.6.18 will be as stable and long lasting as the famous and rock-solid 2.4.18 from Woody. 18 seems to be Debian’s favourite kernel minor version recently. ;-)

Shell Efficiency Talk at DaLUG today //at 02:29 //by abe

I just uploaded the slides for my shell efficiency talk at the Darmstadt Linux User Group (DaLUG) today at 18:30 CEST at the Technical University of Darmstadt. (The talk will be held in German.)

I will also hold a workshop about the same subject on the 29th of October 2005 at Linux-Info-Tag Dresden. (Will also be held in German.)

Probably moving from tcsh to zsh. Bash sucks. //at 02:29 //by abe

The grml-T-Shirt, Alfie was wearing at the Debian QA Meeting in Darmstadt this weekend reminded me, that I wanted to download a grml-ISO. While looking for the ISO I found a link to the grml zsh Reference Card. Beneath the links to the reference card there were a pointer to zsh-lovers, “a small project which tries to collect tips, tricks and examples for the Z shell.”.

There were a lot of nice tricks mentioned, e.g. redirection to multiple files. So I spawned a zsh and checked for the main feature, which keeps me using tcsh instead of bash: History Tab Completion. And see there: zsh does History Tab Completion. And even nicer: Completion results don’t create a new prompt, but just show up (and vanish again with e.g. ^C) beneath the prompt while the prompt only moves (up) if there’s not enough space for all the possible completions. Some kind of meta-cool is the set of configuration variables starting with CSH_JUNKIE_. Guess, I am such a (t)csh junkie. ;-)

And global aliases seem also a very fine (but also very dangerous) feature. Think of cd ... just doing what you want it to, namely cd ../... As well as the advanced history handling which includes incremental sharing with multiple simultaneous shells. Or the spelling corrections based on keyboard layout.

On the other hand, zsh offers everything from bash I missed in tcsh: ^R and usable loops (mostly while (true); do ...) on the command line. The only thing none of the three shells can is Mind Tab Completion. ;-)

The zsh page from Adam Spiers seems to be good source for informations about the zsh. Another nice collection of zsh tips (which often also work in other shells) was in the links section of the grml zsh page.

Funnily several people tried to convince me to use zsh before, but they just didn’t use the right arguments. :-) So it looks as if I found the right arguments by myself and should really give zsh a try after 10 years of tcsh. Although I already found something less amusing in zsh: echo '\n' and echo "\t" behave both very strange, but I still hope, I find the switch to turn it off…

But my upcoming shell efficiency talk will definitely not only feature bash and tcsh but also zsh.
