Compile, install and run it with something like: $ battd -p 10 -e $HOME/bin/beep_speaker And where $HOME/bin/beep_speaker: #/bin/sh TUNE="l2b.f+.p16a.c+.p l4mn<b.>e8a2mspg+e8c+f+8b2" /bin/echo $TUNE > /dev/speaker Which will play "opening bars of the theme from Star Trek Classic" when the battery will reach approximately 10%. There are more tunes in src/usr.sbin/spkrtest/spkrtest.sh, and you can always make your own ;-). A long string of 'A's will produce unpleasant beeping, which will remind you to turn on turn on your power supply :-). HTH. Sarunas
