It can recognize ISO-9660, Ext2, FAT, NTFS, and UFS filesystems. +When the +.Fl u +flag is specified, +.Nm +also recognizes certain additional metadata formats that cannot be +handled using +.Xr mount 8 , +such as ZFS pools and +.Xr geli 8 +providers. +.Pp The filesystem name is printed to the standard output -as, respectively, -.Li cd9660 , -.Li ext2fs , -.Li msdosfs , -.Li ntfs , -or -.Li ufs . +as, respectively: +.Bl -item -offset indent -compact +.It +cd9660 +.It +ext2fs +.It +geli +.It +msdosfs +.It +ntfs +.It +ufs +.It +zfs +.El .Pp Because .Nm is built specifically to detect filesystem types, it differs from .Xr file 1 in several ways. The output is machine-parsable, filesystem labels are supported, the utility runs sandboxed using .Xr capsicum 4 , and does not try to recognize any file format other than filesystems. .Pp These options are available: .Bl -tag -width ".Fl l" .It Fl l In addition to filesystem type, print filesystem label if available. .It Fl s Ignore file type. By default, .Nm only works on regular files and disk-like device nodes. Trying to read other file types might have unexpected consequences or hang indefinitely. +.It Fl u +Include filesystems and devices that cannot be mounted directly by +.Xr mount 8 . .El .Sh EXIT STATUS The .Nm utility exits 0 on success, and >0 if an error occurs or the filesystem type is not recognized. .Sh SEE ALSO .Xr file 1 , .Xr capsicum 4 , +.Xr autofs 8 , +.Xr geli 8 , .Xr glabel 8 , -.Xr mount 8 +.Xr mount 8 , +.Xr zpool 8 .Sh HISTORY The .Nm command appeared in .Fx 11.0 . .Sh AUTHORS The .Nm utility was developed by .An Edward Tomasz Napierala Aq Mt trasz@FreeBSD.org under sponsorship from the FreeBSD Foundation. +ZFS and GELI support was added by +.An Allan Jude Aq Mt allanjude@FreeBSD.org Index: head/usr.sbin/fstyp/fstyp.c =================================================================== --- head/usr.sbin/fstyp/fstyp.c (revision 284588) +++ head/usr.sbin/fstyp/fstyp.c (revision 284589) @@ -1,226 +1,236 @@ /*- * Copyright (c) 2014 The FreeBSD Foundation * All rights reserved. * * This software was developed by Edward Tomasz Napierala under sponsorship * from the FreeBSD Foundation. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.
