# After an update, programs that are still running keep using the old,
# unfixed library until they restart. needrestart checks for that after
# every apt run and lists what needs a restart; it only lists, and never
# restarts anything for you (a restart in the middle of your work, or of
# NetworkManager, would be worse than the wait). It can also pop up a
# desktop notification (libnotify-bin is installed for that).
# Run it yourself any time: sudo needrestart
# Usage: bash needrestart.sh [--remove]
# status: file:/etc/needrestart/conf.d/50-wren.conf
