Installation date?

stf92 · 05-13-2014, 07:28 PM

Hi: if 'ls -ld /' outputs 2014-05-10 as the date, does it mean I did the slackware installation on 2014-05-10?

My output ls:

Code:

drwxr-xr-x 22 root root 4096 May 10 10:32 //

So the format in your case will probably be

Code:

YYYY:MM:DD

Edit: Sorry, completely misread your question.

It probably means that your initrd created the root directory that day. So it would be your last boot date/time.

stf92 · 05-13-2014, 08:08 PM

It's strange, because I've booted many times since that day.

I think you'd be better off looking at the date of your oldest package install:

ls -lt /var/log/packages | tail -n 1

Yeah, my assertion was wrong.

Pat beat me with the correct answer.

But wouldn't it be the latest package install/upgrade?

Typically, yes, unless major modification to the fileseytem were done since that date.

Such as this...

Now you might be able to:

#last

And look for something like:
wtmp begins Fri Jul 6 18:16:16 2012

Thank you very much.

The wtmp database can be re-initialized for whatever reason.

Code:

# last | grep begins
wtmp begins Fri Dec 27 15:51:37 2013

versus

Code:

# ls -lt /var/log/packages/ | tail -n1
-rw-r--r-- 1 root root    2507 Aug  4  2010 aaa_elflibs-13.1-x86_64-1

Code:

tune2fs -l /dev/sdX{1-9}

time of file system creation

None of the hard disks in my server are the original ones when I first installed Slackware on it ;-)
Timestamps of the files that I copied from old to new disks remain the same, but the tune2fs command shows me the date when I formatted that new disk...

... and for the oldest install date for upgraded Slackware:

Code:

ls -lt /var/log/removed_packages/ | tail -n1

Good point. ls packages would indeed be the better choice.
