[Solved]How long have I been using my distro

[maxemilian]

Hello,
I need to check when I installed my distro? Is there any way of checking this on Linux?

Actually, I represent Linux to my friend as proof of how much stable Linux which I have been using for almost more than 2 years without any reinstallation. (knock on wood )

I searched Ddg and google but I can’t found a notable thing.

So Is there any counter in Linux or Log file

My distro Manjaro Cinnamon.

awk -F “[” ‘NR==1 {print $2;}’ /var/log/pacman.log

stat /

[cscs]

stat -c '%w' /

for smaller

(PS @nigelwarning you must fix your quotes for yours to work)

Yeah It is work, but as if show the latest big update time
@tuxmanjarino @cscs

Then that probably means somehow you reinstalled over or reformated root or similar.
I suppose you could check your users home instead?

stat -c '%w' ~

[edit … oh … those quotes got me too. hah. fixed]

[tuxmanjarino]

What @cscs said, maybe you 've used a backup mechanism.

You may find more info in the archived forum for example:

Post your Manjaro installation date

/edit: or this one:

Find the installation date

(base) [axe@axe-20aws2t12n ~]$ stat -c ‘%w’ ~axe
‘2020-04-28 22:51:15.603701161 +0300’

looks better by the way I checked the creation time of any first file like music,Docs as you said home.
But how can I check this

[maxemilian]

Its so interesting…

(base) [axe@axe-20aws2t12n ~]$ sudo tune2fs -l /dev/sda2 | grep “created”
[sudo] password for axe:
Filesystem created: Wed Feb 12 18:58:25 2020

we’re digging deeper and deeper
I started questioning myself Should I did this?
But I don’t know how to use backup
Sorry, I’m a little different person who doesn’t use these.
