Hi, I've heard people can write some scripts and put it in a cron job
that do a dist-upgrade on their system then send what've been upgraded
to their emails. Can someone share how they did it ? thanks
There's a debian package to do this, but I had already rolled my own
when I came across it. I have in /etc/cron.d/apt-upgrade the following
entry:
-8-8-8-8-8-8-8-8-8-
UPGTMP=/var/tmp/.outf.apt-upgrade
30 7,15,23 * * * root /usr/local/sbin/apt-upgrade | tee $UPGTMP
-8-8-8-8-8-8-8-8-8-
which tries to download upgraded packages and send the results to me by
mail, as well as storing them in a log file.
The /usr/local/sbin/apt-upgrade script checks to see if it is already
running, takes access failures into account by retrying a certain number
of times, and downloads all the updated packages (the installation
of the packages should *never* be done automatically).
It goes like this:
-8-8-8-8-8-8-8-8-8-
#!/bin/bash
BASE=/var/tmp
LOCK=$BASE/.lock.apt-upgrade
DONE=$BASE/.done.apt-upgrade
MAXTRIES=5 # retry limit
SLEEPSECS=300# seconds to sleep between retries
SEP=
echo $SEP ; echo $0 ; echo $SEP ; date ; echo $SEP ; echo
if [ -e $LOCK ] ; then
