Quick and dirty hardware summary where lshw is not available. Requires util-linux, procps, pciutils, usbutils and net-tools, which should be preinstalled on most systems.
It is the same but more faster real 0m0,007s user 0m0,011s sys 0m0,000s with my solution real 0m0,038s user 0m0,044s sys 0m0,000s with your solution :) Show Sample Output
As of this writing, this requires a fairly recent version of util-linux, but is much simpler than the previous alternatives. Basically, lsblk gives a nice, human readable interface to all the blkid stuff. (Of course, I wouldn't recommend this if you're going to be parsing the output.) This command takes all the fun out of the previous nifty pipelines, but I felt I ought to at least mention it as an alternative since it is the most practical.
Use lsbk (list block) and jq (to manipulate a JSON on the command line) to display partition information: Show Sample Output
Another alternative to blkid, lsblk, file -s, cat /proc/paritions, fdisk -l, etc.. Show Sample Output
