.Sh NAME
.Nm fsck
.Nd filesystem consistency check and interactive repair
.Sh SYNOPSIS
.Nm fsck
.Op Fl dvplfyn
.Op Fl l Ar maxparallel
.Op Fl t Ar fstype
.Op Fl T Ar fstype:fsoptions
.Ar special | node ...
.Sh DESCRIPTION
The
.Nm
command invokes filesystem-specific programs to check the
special devices listed in the
.Xr fstab 5
file or in the command line for consistency.
The options are as follows:
.Bl -tag -width Ds
.It Fl d
Debugging mode.
Just print the commands without executing them.
Available only if
.Nm
is compiled to support it.
.It Fl f
Force checking of filesystems, even when they are marked clean (for filesystems
that support this).
.It Fl l Ar maxparallel
Limit the number of parallel checks to
.Ar maxparallel .
By default, the limit is the number of
disks, running one process per disk.
If a smaller limit is given,
the disks are checked round-robin, one filesystem at a time.
.It Fl n
Cause
.Nm
to assume
.Dq no
as the answer to all operator questions, except
.Dq CONTINUE? .
This is assumed to be the default when dealing with filesystems currently
mounted writeable.
.It Fl p
Enter preen mode.
.It Fl t Ar fstype
Invoke fsck only in the comma separated list of filesystem types.
If the list starts with
.Dq no ,
invoke fsck only in the filesystem types that are
.Em not
specified in
the list.
.It Fl v
Print the commands before executing them.
.It Fl y
Cause
.Nm
to assume
.Dq yes
as the answer to all operator questions.
.It Fl T Ar fstype:fsoptions
List of comma separated filesystem specific options for the specified
filesystem type, in the same format as
.Xr mount 8 .
