Kfscmd
issues commands to a
kfs(4)
server that was started with the
-n
option to create a control file.
Kfscmd's
own
-n
option names the file system to which the
cmd
applies; it is
main
by default.
The known commands are described below.
Note that some commands are multiple words (eg,
check
and its flags) and
should be quoted to appear as a single argument to
sh(1).
allow
Turn permission checking off (to simplify administration).
Equivalent to the
-P
and
-W
options to
kfs(4).
allowoff
disallow
Turn permission checking on (again).
