fstyp
utility is used to determine the file system
type on a given device. It can recognize ISO-9660, Ext2, FAT, NTFS, and UFS
file systems. When the -u
flag is specified,
fstyp
also recognizes certain additional metadata
formats that cannot be handled using
mount(8), such as ZFS pools.
The file system name is printed to the standard output as, respectively:
Because fstyp
is built specifically to
detect file system types, it differs from
file(1) in several ways. The
output is machine-parsable, file system labels are supported, and it does
not try to recognize any file format other than file systems.
These options are available:
-l
-s
fstyp
only works on
regular files and disk-like device nodes. Trying to read other file types
might have unexpected consequences or hang indefinitely.-u
fstyp
utility exits 0 on success, and >0 if an
error occurs or the file system type is not recognized.
