Use file(1) to view device information

file(1) can print details about certain devices in the /dev/ directory (block devices in this example). This helped me to know at a glance the location and revision of my bootloader, UUIDs, filesystem status, which partitions were primaries / logicals, etc.. without running several commands. See also: file -s /dev/dm-* file -s /dev/cciss/* etc.. Show Sample Output

file -s /dev/sd*
