This article will explain in detail how to use the blkid command in Linux. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Under Linux, you can use the blkid command to query the type of file system used on the query device. Blkid is mainly used to query the file system type, LABEL, UUID and other information used by the block devices of the system (including swap partitions). To use this command, you must install the e2fsprogs package

Blkid views the file system type, LABEL, UUID and other information of block devices
