When Did I Install Linux

Find Linux Installation Date

If you can’t remember when you installed Linux, you can try this:

[code]ls -lt /var/log/installer[/code]

The output will be similar to this:

[code]$ ​​ls -lt /var/log/installer
total 6796
-rw-r–r– 1 root root 431 Jul 4 16:25 telemetry
-rw-r–r– 1 root root 60 Jul 4 16:25 media-info
-rw——- 1 syslog adm 6548069 Jul 4 16:25 syslog
-rw——- 1 root root 386671 Jul 4 16:16 partman
-rw——- 1 root root 2867 Jul 4 16:15 debug
-rw——- 1 root root 18 Jul 4 16:07 version
-rw——- 1 root root 1812 Jul 4 16:04 casper.log[/code]

As you can see, it was installed on the 4th of July. Note that it doesn’t give the year. You should probably already know what year it was installed.
