Which displays the underlying device and size (in GiB) for the attached ramdisk. Command validation is moved to the bottom of the routine as a fallback. This elides one place of repetition.
Also fix GiB (it was GB) and abstract the human-readable byte display (cribbed from https://unix.stackexchange.com/a/4691/115271).
I tested this manually in ZSH and had pushed without making sure Bash had no problems. Turns out it did, the command would complete and dump the user back at the prompt before all the output was done. Adding cat at the end of the pipeline ensures that Bash will not return until the subprocesses have completed. This seems to address the issue. I've also centralized some of the repeated complexity within the pipeline at the cost of simpler repetition.

This shows some info about the attached ramdisk, like the underlying device and size for the attached ramdisk.
Command validation is moved to the bottom of the routine as a fallback. This elides one place of repetition. A function is added to convert bytes to something human readable.
