This command only applies in [[:multiuser]] mode.

===== Default Keybindings =====

None.

===== Syntax =====

  * ''**aclchg** //usernames// //permbits// //list//''
  * ''**chacl** //usernames// //permbits// //list//''

===== Description =====

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 and/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 window 2:  '''aclchg //username// -w+w 2'''.  To allow read-only access to the session:  '''aclchg //username// -w <nowiki>"#"</nowiki>'''.  As soon as a user's name is known to ''screen'', the user can attach to the session and (per default) has full permissions for all command and windows.  Execution permission for the acl commands, '''[[commands:at]]''' and others should also be removed or the user may be able to regain write permission.  Rights of the special username ''nobody'' cannot be changed (see the "''[[commands:su]]''" command).
