The command you provided is used to create a File Allocation Table (FAT) file system on a specific storage device. Here is a breakdown of each part:

mkfs.vfat: This is the command to create a FAT file system. It is used to format a storage device with the FAT file system.
-f 5: This option specifies the number of file allocation tables to create. In this case, it is set to 5, which means 5 separate tables will be created for file allocation.
${-dev-sdb1}: This part specifies the target device or partition where the file system will be created. In this example, it is sdb1, which refers to the first partition on the sdb disk.

Note that the ${-dev-sdb1} part may contain a typo or incorrect format. Typically, the correct format for specifying a device is without the hyphen, like this: /dev/sdb1.
