archup is a small C application which informs the user when system-updates for Archlinux are available. It's licenced under the GPLv3. In contrast to other update notifiers archup is intended to be lightweight and just do what it should: notify about possible updates.
archup uses GTk+ and libnotify to show a desktop notification if updates are available. It follows the unix-philosophy of "just doing one thing, but doing it well". It just notifies about new updates but the packagedatabase has to be updated by the user (better said a cronjob). With a cronjob archup can be used to regulary check for new updates and get a desktop notification if there are some.
From the AUR
Install AUR.AUR from the
Get a working-copy of archup:
git clone git://git.sv.gnu.org/archup.git
Change to the directory of the downloaded source and then follow the commands below:
$ autoconf $ ./configure $ make $ make install
This installs the binary to
/usr/bin/archup and the other files to
archup can simply be invoked by executing it from the commandline. But you surely want to automate this task and let archup continouisly be run with a cronjob.
The most simple setup is for a single user system where you want to check once an hour for updates. In this case just copy the
# cp /usr/share/doc/archup/cronhourly.example /etc/cron.hourly/archup.sh
and make it executable with
# chmod 755 /etc/cron.hourly/archup.sh
Do not forget to open this file with a text editor of your choice and change the username of the arch_user value with your username.
Now every hour your package database will get updated and after that archup will be executed. If there are updates archup shows a desktop notification, if there are no updates nothing will happen. The desktop notification will automatically disappear after 60min or if you simply click on it.
If you want to execute archup at other intervals than hourly you are free to do so simply by setting up a custom cronjob (read
man cron for more on this).
Some hints on this:
- you can adjust the timeout value, before the notification will disappear with the --timeout option of archup.
- you should take care that the packagedatabase gets updated by executing
/usr/bin/pacman -Sybefore archup gets executed.
- if you wanna start a graphical application from a cronjob you propably have to set the
XAUTHORITYvalues. The best is taking a look at
/usr/share/doc/archup/cronhourly.exampleand get your inspiration there.
#!/bin/bash arch_user=rorschach if [ -z "$(pgrep pacman)" ];then /usr/bin/pacman -Sy > /dev/null fi XAUTHORITY=/home/$arch_user/.Xauthority DISPLAY=:0.0 /usr/bin/archup --uid $(id -u $arch_user)
If you want to use patch for notify-osd which fixes this.AUR, be aware that notify-osd doesn't respect libnotify timeouts and thus the notifications will disappear in the regular notify-osd interval and not in the one you tell archup. But there's a
