pacnanny is yet another wrapper script for
pacman, the package
manager of Arch Linux and its various derivatives (I use
Parabola GNU/Linux-libre). Unlike other
wrappers, this script does not aim to make up for any perceived
shortcomings in the functionality of
pacman. Instead, it aims to
make up for shortcomings in the users of
pacman. The goal of
pacnanny is to make it even harder to mess up with
making sure that you do not miss anything important.
pacnanny does the following:
- Before doing a system update, check for new Arch Linux news items since the last update and display them one at a time in the browser of your choosing (w3m by default). There is no confirmation or option to skip this. Your eyeballs are required to look at the news.
- Reprint all warnings again together after the update is completed.
- List new
- Print a warning and ask for confirmation when using the
- Prompt for a reboot when the kernel has been upgraded.
pacnanny is a thin wrapper that only looks at the arguments you pass
before passing them on and at the output that
pacman produces. You
can simply use the
pacnanny command in place of
pacman and use all
the familiar arguments. So, to do a system update, you would do
As careful as I try to be when I run
pacman -Syu, I still
occasionally miss things, particularly during large updates that
produce a lot of text. Important warnings sometimes slip between the
cracks, causing me to miss an important new
.pacnew file, for
example. As for the news, I do subscribe to the RSS feed but sometimes
I update the system before opening my newsreader. This forces me to
see the news first.
Are there other places that we can help the user avoid shooting himself in the foot? I'm open to ideas. Contributions are welcome as long as they stick to the basic idea of only trying to correct/prevent user-error/carelessness. Also, I'm not great at shell scripting, so please point out any mistakes or places for improvement.
