Use it all the time. You can even use uname in a script to help you get host name information (though you can get it in other ways. Most systems provide host name in a system environment variable, but the environment variable had to be created some way!

On Linux systems, the /proc directory provides all the information about all process activity on your system. You can find out where disks are located, partitions, memory, peripherals, as well as the name and number of processes that are running.

Uname in the Linux implementation probably gets its information from there (unless it was implemented prior to the /proc setup, in which case it may use another method).
