fstyp(1M)


fstyp (generic) -- determine filesystem type

Synopsis

fstyp [-v] special

Description

fstyp allows the user to determine the filesystem type of unmounted filesystems using heuristic programs.

An fstyp module for each filesystem type to be checked is executed; each of these modules applies some appropriate heuristic to determine whether the supplied special file is of the type for which it checks. If it is, the program prints on standard output the usual file-system identifier for that type and exits with a return code of 0; if none of the modules succeed, the error message ``unknown_fstyp (no matches)'' is returned and the exit status is 1. If more than one module succeeds the error message ``unknown_fstyp (multiple matches)'' is returned and the exit status is 2.

Command options

-v
Produce verbose output. This is usually information about the filesystems superblock and varies across different FSTypes.

Notices

The use of heuristics implies that the result of fstyp is not guaranteed to be accurate.
