Re: [dwm] Basic dwm usage question
greetings, As you can see I have the echo command sleep for 60 seconds. I was using 1 second, but found my load nearly doubles. My problem is when I i had this problem with using dwm on my Toshiba Libretto 100CT (cute and small laptop with 32M RAM and a 266mhz pentium). I investigated, and found that these things together (the shell, sed, etc) use quite a bit of system resources - especially the shell. I myself solved the problem by writing a small script interpreter with very small resource usage that just had enough power built in to do the necessary tasks (reading the relevant data from /proc and /sys, assembling and printing a status line); I would imagine this could be done with any other reasonably fast scripting language (especially a not marksweep GC-d one (python?)). The main thing is to avoid all the forking and piping. If you really want, I can give out my own interpreter, but it's shamefully dirty :) regards, Mate Nagy

[dwm] Basic dwm usage question
Hello list,
I've recently switched over to dwm full time. I run it on OpenBSD 4.1
-release and couldn't be happier. I just have a simple question about
how dwm quits. I use the following command in my .xinitrc to start dwm:
while true
do
echo [ B: `/usr/sbin/apm -l`% T: `/sbin/sysctl hw.sensors.aps0.temp0 \
| sed 's/hw.sensors.aps0.temp0=//g' | sed 's/.00//g' | awk '{print \
$1}'`C ] [ `uptime | perl -e ' =~ \
/\s+([0-9.]+),\s+([0-9.]+),\s+([0-9.]+)/;print qq[$1, $2, $3];'` ] [ \
`date +%m/%d/%y %H:%M` ]
sleep 60
done | dwm
As you can see I have the echo command sleep for 60 seconds. I was
using 1 second, but found my load nearly doubles. My problem is when I
run Alt + Shift + q to quit dwm I find X hangs for awhile before
existing. I assume it hangs for as long as the time is left for the
sleep command, depending where it is when i quit dwm. I was wondering
if there is away to kill sleep as soon as I quit dwm? Thanks for the
help as I imagine it's not dwm specific.

Re: [dwm] Basic dwm usage question
That's also a question I wanted to ask :) Even though I didn't notice any load increase when using 1 second (I'm just displaying the date), I didn't like the idea of having it to refresh so often needlessly. So I increased to 60 seconds, but ran into the problem you mention, so I set it to 5 seconds because of that.

Thanks for the help as I imagine it's not dwm specific. You can look on snippet of my ~/.Xsession file: http://na.srck.net/dwm/Xsession-snippet it updates datetime every second, but load and diskcpu temperature only each 15 seconds. Also there is outer BIG loop so I am able to reload dwm (via dwm quit). To end the session I can use c-a-backspace (- Xserver quits and all the program it was running too). -- Premysl Anydot Hruby http://na.srck.net Thanks for everyone hints. I'd rather not have to run c-a-backspace (which I do now). I'd prefer dwm to quit and the xsession to terminate normally. I did find this posting: http://www.suckless.org/pipermail/dwm/2006-July/19.html and am following it now. I believe it to be the answer to my problem. -- James Turner BSD Group Consulting http://www.bsdgroup.org
Re: [dwm] Basic dwm usage question
Alright, after browsing the archive I was able to whip up a working
solution. In my .xinitrc I have:
[ -p .dwm-status ] || mkfifo $HOME/.dwm-status
$HOME/.dwm.in
exec dwm $HOME/.dwm-status
In .dmw.in I have:
#!/bin/sh
while true
do
echo [ B: `/usr/sbin/apm -l`% T: `/sbin/sysctl hw.sensors.aps0.temp0 \
| sed 's/hw.sensors.aps0.temp0=//g' | sed 's/.00//g' | awk '{print \
$1}'`C ] [ `uptime | perl -e ' =~ \
/\s+([0-9.]+),\s+([0-9.]+),\s+([0-9.]+)/;print qq[$1, $2, $3];'` ] [ \
`date +%m/%d/%y %H:%M` ] ~/.dwm-status
sleep 60
done
I'm now able to use alt+shift+q and dwm and the xsession exits like I
would expect!
