I understand that few main ways to obtain information about the current OS for a Raspbian/Debian system is via :
cat /etc/os-releasewhich will give me sufficient information about the Version of Jessie.
cat /etc/debian_versionjust show the current version number
I can do
uname -ato obtain information about the kernel version and data for date of the kernel etc.
But for instance, I have Two raspberry Pis one with Raspbian Jessie which was downloaded in the late 2016 and one with Raspbian Jessie-Lite which was downloaded in recent February 2017.
Is there any way to determine which Jessie version is the latest on either of the two pis?
since the Download Page for Jessie has some information about the Release Date and Version how can I obtain that same information on the Pi.
