OPTIONS

The following options are supported: -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

Example 1: Examples of the nischmod command. This example gives everyone read access to an object. (that is, 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
