8.4.7 aclumask

Command: aclumask [[users]+bits |[users]-bits .... ]

Command: umask [[users]+bits |[users]-bits .... ]

(none)
This specifies the access other users have to windows that will be created by the caller of the command. Users may be no, one or a comma separated list of known usernames. If no users are specified, a list of all currently known users is assumed. Bits is any combination of access control bits allowed defined with the aclchg command. The special username `?' predefines the access that not yet known users will be granted to any window initially. The special username `??' predefines the access that not yet known users are granted to any command. Rights of the special username nobody cannot be changed (see the su command). Umask is a synonym to aclumask.
