 Posted: Thu Apr 29, 2004 7:05 am Post subject: check if I got mail |
 |
|
I got a led on my laptop I can get to blink if I want to and want it to blink when I got new mail. Does anyone know if there is a deamon (really a deamon, running from a init-script for example, not demping on X) in portage (and if not, could tell me where I can find something to compile myself) who can check if there is mail in my local maildir/mbox and run a given command?
Have looked through net-mail/ and the searched the forum but havn't found anything that looks like something like this.
Thanks in advance!

I have no idea about such a demon, but you could probably write a small bash script that checks the contents of .maildir/new and starts blinking the led if there is new mail. When there is no more new mail it stops the blinking.
You could then run that script from cron every minute or so.

Yeah, of course. Seems obvious now. Cron doing the deamon job. Thanks.

You're welcome.
BTW, how do you control the led?

I have a Acer TravelMate 620 who got some shortcut buttons and a mail led. It has been made a couple of kernel modules for the travelmate (#1,#2) that use the input system in the kernels to add support for the buttons and adds support for the led. To get the led blinking (there is only to states: off and blinking) you can with the acerhk driver do as follows:
| Code: | | # echo on > /proc/driver/acerhk/led |
#1: http://www.informatik.hu-berlin.de/~tauber/acerhk/
#2: http://www.math.columbia.edu/~jensen/linux/acertm/

| Just purely out of interest, how are you going to stop it blinking? Either have the cron daemon time out or are you going to manually reset the LED? |

BTW, I found a script to do the job (from one who needed to do the same thing) when I searched for information about how to get the module working.
This should also answer Celtis question:

This one check if there is new mail in .maildir/new:
| Code: | #!/bin/sh
if [ -z "$UHOME" ]; then
UHOME=$HOME
fi
MAILDIR=$UHOME/.maildir
MAIL=`ls -A $MAILDIR/new/`
if [ -z "$MAIL" ]; then
exit 0
fi
exit 1 |
And this one use the other scripts and lights the led if there is new mail and turns it off if .maildir/new is empty:
| Code: | #!/bin/sh
DEV=/proc/driver/acerhk/led
[ -f $DEV ] || exit 0
USER="$(who | awk '/./ { if ( $2 == ":0" ) print $1 }')"
if [ ! -z "$USER" ]; then
LED="off"
UHOME="/home/$USER" /usr/local/bin/maildir-new
if [ "$?" == "1" ]; then
LED="on"
fi
echo $LED > $DEV
fi |
The guy(could actually not find his name on his personal site;-) who made this script also got a nice tutorial for installing gentoo on TravelMate 630:

All credit goes to him

Cool, I must go and have a look at my vaio to see if it's got anything like that too. 
Thanks for posting the scripts and the links.

The cron job turns the led on or off, depending on what it finds in the maildir.
