NAME

fstyp - identify file systems

SYNOPSIS

fstyp device

fstyp [-hV]

DESCRIPTION

The fstyp command tries to guess the filesystem type of a device and outputs its findings.

If a filesystem can be successfully identified, its name is printed and 0 returned.

If no known superblocks can be found, fstyp prints an empty string and returns a non-zero value.

fstyp is often used in backup scripts to pick dump and restore commands appropriate for the filesystem type.

Since fstyp relies on heuristics to identify the filesystem, there is no guarantee for correct results.

The detection algorithm used in fstyp is the same as in the mount(8) command.
