fstyp(1M)

DESCRIPTION

The fstyp command allows the user to determine the file system type of a mounted or unmounted file system. special represents a device special file (for example: /dev/dsk/c1t6d0).

The file system type is determined by reading the superblock of the supplied special file. If the superblock is read successfully, the command prints the file system type identifier on the standard output and exits with an exit status of 0. If the type of the file system cannot be identified, the error message unknown_fstyp (no matches) is printed and the exit status is 1. Exit status 2 is not currently returned, but is reserved for the situation where the file system matches more than one file system type. Any other error will cause exit status 3 to be returned.

The file system type is determined by reading the superblock of the supplied special file.
