Linux Command - uname

The Linux command uname is used to print out information about the kernel, OS, and platform.

Typically you would just use the command like this to get all info:

uname -a

You might use one of the other options for example if you need to set a variable in a script or command to grab a specific verison of a package.

Here is an example of that:

sudo apt-get --reinstall install linux-headers-`uname -r`
