8.4.3 Aclchg
------------
-- Command: aclchg USERNAMES PERMBITS LIST
-- Command: chacl USERNAMES PERMBITS LIST
(none)
Change permissions for a comma separated list of users. Permission
bits are represented as 'r', 'w' and 'x'. Prefixing '+' grants the
permission, '-' removes it. The third parameter is a comma
separated list of commands or windows (specified either by number
or title). The special list '#' refers to all windows, '?' to all
commands. If USERNAMES consists of a single '*', all known users
are affected. A command can be executed when the user has the 'x'
bit for it. The user can type input to a window when he has its
'w' bit set and no other user obtains a writelock for this window.
Other bits are currently ignored. To withdraw the writelock from
another user in e.g. window 2: 'aclchg USERNAME -w+w 2'. To allow
read-only access to the session: 'aclchg USERNAME -w "#"'. As soon
as a user's name is known to screen, he can attach to the session
and (per default) has full permissions for all command and windows.
Execution permission for the acl commands, 'at' and others should
also be removed or the user may be able to regain write permission.
'Chacl' is a synonym to 'aclchg'. Multi-user mode only.
