Check last time I upgraded

Hi,
Is there any way to know when I last upgraded my system ?

Thanks Debasish

Re: Check last time I upgraded

look at the file /var/log/pacman.log. You can also use the following command:

awk '/full system upgrade/ { save=$0 }END{ print save }' /var/log/pacman.log

--edit: or better, to show only the date and time

awk '/full system upgrade/ { dt=$1; tm=$2 } END { print dt,tm }' /var/log/pacman.log

Check /var/log/pacman.log

You can also know it package by package by doing :

pacman -Qi package

Op may find this small shell script of use ..  edit to suit

#!/bin/bash
export DISPLAY=":0.0"
LASTUPD="$(echo -e "Pacman Last Upgraded: " ; cat /var/log/pacman.log | grep upgraded | head -n 1 | cut -c 2-17)"
  
  notify-send -i ~/.icons/pacman3.png  "$LASTUPD" 

exit

Re: Check last time I upgraded

I don't think that does what you think it does, cirrus. At the very least you probably want to switch out 'head' for 'tail'.

Wormzy, it seems to work ... but...

grep + head + cut = awk.

cat + grep + head + cut = stupid.

echo + cat + grep + head + cut = stupid and confusing.

Re: Check last time I upgraded

Oh, absolutely. As mauritiusdadd's post demonstrates, awk is the way to go.

I was just pointing out to cirrus that their script shows the time of the first package upgrade. At the very least they should use tail, but they'd be better off throwing out the entire pipeline and using awk instead.

Re: Check last time I upgraded

Also why does it hardcode DISPLAY when you can simply run the script within X?
