SYNOPSIS
nischmod [ -AfLP ] mode name...
AVAILABILITY
SUNWnisu
DESCRIPTION
nischmod changes the access rights (mode) of the NIS+
objects or entries specified by name to mode. Entries are
specified using indexed names (see nismatch(1)). Only prin-
cipals with modify access to an object may change its mode.
mode has the following form:
rights [, rights]...
rights has the form:
[ who ] op permission [ op permission ]...
who is a combination of:
n Nobody's permissions.
o Owner's permissions.
g Group's permissions.
w World's permissions.
a All, or owg.
If who is omitted, the default is a.
op is one of:
+ To grant the permission.
- To revoke the permission.
= To set the permissions explicitly.
permission is any combination of:
r Read.
m Modify.
c Create.
d Destroy.
OPTIONS
-A Modify all entries in all tables in the concatenation
path that match the search criteria specified in name.
This option implies the -P switch.
-f Force the operation and fail silently if it does not
succeed.
-L Follow links and change the permission of the linked
object or entries rather than the permission of the
link itself.
-P Follow the concatenation path within a named table.
This option is only applicable when either name is an
indexed name or the -L switch is also specified and the
named object is a link pointing to an entry.
EXAMPLES
This example gives everyone read access to an object.
(i.e., access for owner, group, and all).
example% nischmod a+r object
This example denies create and modify privileges to group
and unauthenticated clients (nobody).
example% nischmod gn-cm object
In this example, a complex set of permissions are set for an
object.
example% nischmod o=rmcd,g=rm,w=rc,n=r object
This example sets the permissions of an entry in the pass-
word table so that the group owner can modify them.
example% nischmod g+m '[uid=55],passwd.org_dir'
The next example changes the permissions of a linked object.
example% nischmod -L w+mr linkname
ENVIRONMENT
NIS_PATH If this variable is set, and the NIS+ name
is not fully qualified, each directory
specified will be searched until the
object is found (see nisdefaults(1)).
EXIT CODES
nischmod returns 0 on success and 1 on failure.
