NAME

ted − interactive /etc/ttys file editor

SYNTAX

ted

DESCRIPTION

The ted command allows modification of the /etc/ttys file without the use of an editor.  The ted command insures that only valid user devices are created, removed, or otherwise modified by checking that, for each transaction, a valid device name exists in the /dev directory. 

There are a variety of commands available once ted is invoked.  Terminals may be enabled and disabled using the “modify” command.  New entries are created using the “create” command, entries are removed with the “remove” command.  General ted information is available at the main menu by entering “help ted”.  Additional help while using ted is available with the “help” command. 

The ted program maintains an internal list of the changes made to the /etc/ttys file.  Initially this list is a duplicate of the /etc/ttys file.  The list is updated following each newly entered transaction.  The list may be examined at any time using the “print” command.  The original /etc/ttys file complete with all of the current modifications is printed.  The “print” command lists the major and minor device numbers along with the name and mode of each terminal. 

Changes are not actually written to the /etc/ttys file permanently until the user executes the “write” command.  The proposed changes are printed whereupon the user has the option of writing over the existing /etc/ttys file, or discarding the changes and starting over. 

It is recommended that ted be run in single-user mode to avoid inadvertently disabling any active user terminals. 

In multiuser mode ted may only be run by the superuser.
