I was just wondering how old is my Dell Precision. So I asked DuckDuckGo “how old is your linux” and it told me to to read how old is your linux installation on documentacoes.wordpess.com

sudo tune2fs -l $( df -h | awk '$NF ~ "/$" {print $1}' ) | grep created

Well, I knew it. I was slightly surprised to discover that my main machine is from 2013 and its installation went fine throught a full change of CPU.
