NAME
kfscmd, kfswiz - kfs administration
SYNOPSIS
disk/kfscmd [-n name] cmd ...
disk/kfswiz
DESCRIPTION
Kfscmd issues commands to the kfs(3) device. The -n option
names the file system to which the cmd applies (the main
file system by default).
The known commands are described below. Note that some com-
mands are multiple words and should be quoted to appear as a
single argument to sh(1).
allow Turn permission checking off (to simplify adminis-
tration).
disallow Turn permission checking on.
halt write all changed blocks and stop the file system.
help print the list of commands.
cfs[name] Apply subsequent commands to file system name; the
main file system by default.
rename file name
Change the name of file to name.
newuser user
Add user to /adm/users and make the standard
directories needed for booting.
remove file
Remove file and place its blocks on the free list.
clri file Remove file but do not place the blocks on the
free list. This command can be used to remove
files that have duplicated blocks. The non-
duplicate blocks can be retrieved by checking the
file system with option f (see below).
create file owner group mode [adl]
Create the file. Owner and group are users in
/adm/users and mode is an octal number. If pre-
sent, `a' creates an append only file, `d' creates
a directory, and `l' creates a file that is

exclusive-use.
sync write to disk all of the dirty blocks in the mem-
ory cache.
user Re-initialize authentication information by read-
ing /adm/users.
check [PRdfprtw]
Check the file system. The options are
p print the names of directories as they are
checked.
P print the names of all files as they are
checked.
r read all of the data blocks and check the
tags.
f rebuild the list of free blocks.
d delete redundant references to a block.
t fix bad tags.
c fix bad tags and clear the contents of the
block.
w write all of the blocks that are touched.
readonly Reject file system operations that would update
the device. readwrite Allow the device to be
updated. flashwrite Suppress updates of access
times to reduce the number of writes to the
device; intended for use on file systems in flash
memory, with or without ftl(3).
Kfswiz reads a kfs image from its standard input and writes
a kfs image to its standard output, converting the file sys-
tem data structures from big-endian to little-endian or
vice-versa. This allows an image to be created by a machine
that uses one byte order for use on a machine that uses the
other.

not kfscmd's standard output.
