Options
- -A

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.
Notes
Unlike the system
chmod
command, this command does not accept an
octal notation.
EXAMPLES
Give everyone read access to an object (that is,
access for owner, group, and all):
Deny create and modify privileges to
group
and unauthenticated clients
(nobody):
Set a complex set of permissions for an object:
nischmod o=rmcd,g=rm,w=rc,n=r object
Set the permissions of an entry in the password
table so that the group owner can modify them:
nischmod g+m '[uid=55],passwd.org_dir'
Change the permissions of a linked object:
nischmod -L w+mr linkname
EXTERNAL INFLUENCES
Environment Variables
- 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)).
RETURN VALUE
nischmod
returns
0
on success and
1
on failure.
WARNINGS
HP-UX 11i Version 2 is the last HP-UX release on which NIS+ is
supported.
LDAP is the recommended replacement for NIS+. HP fully supports
the industry standard naming services based on LDAP.
