ttyupd(ADM)                     19 June 1992                     ttyupd(ADM)


 Name

    ttyupd, termupd - update the Terminal Control database

 Syntax

    /tcb/bin/ttyupd

 Description

    ttyupd attempts to create Terminal Control database entries for terminals
    present in the /etc/inittab file but not present in the Terminal Control
    database.  ttyupd calls ale(ADM) passing the Terminal Control database
    and the script termupd as parameters.

    termupd produces an updated version of the Terminal Control database in
    the lockfile created by ale.  termupd generates a list of the terminals
    in /etc/inittab and substitutes the name of the real terminal for any
    alias (in the Device Assignment database).  Next termupd makes a list of
    the terminals in the Terminal Control database. Finally the Terminal Con-
    trol database is copied to the lockfile and any terminals appearing in
    the first list but not the second are added to the end of the lockfile.

 Files

    /etc/auth/system/files          File Control database
    /etc/auth/system/devassign      Device Assignment database
    /tcb/lib/auth_scripts/termupd   update shell script
    /etc/inittab                    script for init process

 Diagnostics

    ttyupd returns the exit status of ale.

    termupd returns 0 if entries are added, 1 if it detects an error and 2 if
    there are no entries to add. Errors cause appropriate error messages to
    be displayed.

 Notes

    Although ttyupd is installed with execute permission for all, because it
    calls ale, the auth subsystem and chown kernel authorizations are
    required to successfully execute ttyupd.
