Show how old your linux OS installtion is

..not guaranteed to always be accurate but fun to see how old you Linux installation is based on the root partitions file system creation date.

What others think

This is cool!

A very slight simplification:

sudo tune2fs -l $(df --output=source / | tail -1) | grep -i created

If you do it like this:

# tune2fs -l `df --output=source / | tail -1` | grep -i created

It'll also work on all Bourne compat shells, not only BASH.

Could be improved by just adding -l option to df, in order not to add delay for non local FS:

sudo tune2fs -l $(df -lh / |(read; awk '{print $1; exit}')) | grep -i created

tune2fs -l $(mount | awk '/ \/ / {print $1}') | grep -i created

If your are cloning, ghosting or using Acronis to distribute your OS this command reflects the image create not how old that particular hardware installation is.

I tested this on a system I just "built" from an Acronis backup and the date was before the server was even manufactured.
