Hi,
I have a little problem with this fish script:
--8<---------------cut here---------------start------------->8---
#!/bin/fish
set -l TITLE ""
cpubar > ~/.cpubar.log &
# the while has to run in a new subshell so that its output goes into
# the pipe directly. Else the output would be blocked till the while
# finishes.
fish -c 'while true;
# notifications
set TITLE (status-show)
# dnamicLog stuff
set TITLE $TITLE "|" (tail -n 1 ~/.xmonad.log)
# battery
set TITLE $TITLE "|" (battery-status)
# cpubar
set TITLE $TITLE "|" (tail -n 1 ~/.cpubar.log)
# cpufreq
set -l cpufreq ""
set -l i 0
set -l lines (cat /proc/cpuinfo | grep "cpu MHz" | \
sed -e "s/^.\+: //" | sed -e "s/\.[0123456789]*//")
for l in $lines
set cpufreq $cpufreq "CPU$i: $l"
set i (echo $i+1 | bc)
end
set TITLE $TITLE "|" $cpufreq
# date
set TITLE $TITLE "|" (date "+%a %F %T")
echo $TITLE
sleep 1
end' | dzen2 -p -ta r -fn fixed -fg '#FFFFFF' -bg '#3F4C6B' -e \
'button3=exec:urxvt.sh;entertitle=uncollapse,unhide;leavetitle=collapse'
killall cpubar
--8<---------------cut here---------------end--------------->8---
My problem is, that I want to kill all programs started with this script
when the script is killed, too.
Currently only cpubar is killed then, but dzen2 and the subshell running
the while loop go on. Because there are many fish shells and sometimes
more than one dzen2 running, I cannot kill them by name.
So is there a way to get the pid of a prozess when or after I started
it? Something like $_, but with the pid of the process would be great.
Thanks,
Tassilo
