FSTYP_HFS(8) BSD System Manager's Manual FSTYP_HFS(8)NAME
fstyp_hfs -- check for an HFS volume
SYNOPSIS
fstyp_hfs device
DESCRIPTION
The fstyp_hfs utility is not intended to be run directly, but rather called by fstyp(8) while it is trying to determine which file system
type is present on the given device. It returns 1 if it thinks the device contains an HFS volume, and 0 otherwise.

fstyp -- determine filesystem type
SYNOPSIS
fstyp [-l] [-s] special
DESCRIPTION
The fstyp utility is used to determine the filesystem type on a given device. It can recognize ISO-9660, Ext2, FAT, NTFS, and UFS filesys-
tems. The filesystem name is printed to the standard output as, respectively, cd9660, ext2fs, msdosfs, ntfs, or ufs.
Because fstyp is built specifically to detect filesystem types, it differs from file(1) in several ways. The output is machine-parsable,
filesystem labels are supported, the utility runs sandboxed using capsicum(4), and does not try to recognize any file format other than
filesystems.
These options are available:
-l In addition to filesystem type, print filesystem label if available.
-s Ignore file type. By default, fstyp only works on regular files and disk-like device nodes. Trying to read other file types might have
unexpected consequences or hang indefinitely.
EXIT STATUS
The fstyp utility exits 0 on success, and >0 if an error occurs or the filesystem type is not recognized.
SEE ALSO file(1), capsicum(4), glabel(8), mount(8)HISTORY
The fstyp command appeared in FreeBSD 11.0.
AUTHORS
The fstyp utility was developed by Edward Tomasz Napierala <trasz@FreeBSD.org> under sponsorship from the FreeBSD Foundation.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
