So I have an alias that I use for performing updates that cleans up old kernels and stuff. Problem is that it doesn't notify me immediately if a reboot is required afterwards. What can I use to figure this out so that I can at least print a message to the screen?

alias update='sudo apt-get update;sudo apt-get dist-upgrade;sudo apt autoremove;'

The package manager creates a file, /var/run/reboot-required, if the installation requires a reboot. This file is deleted when the machine is restarted.

  • Does it have a format or is it an empty file?

  • @Xaxon I believe it's empty, but you just need to check if it exists (e.g. with [ -f /var/run/reboot-required ]). Also BTW, you should write a function or a script, since they're much more flexible than aliases.
