TOPS-20 Commands Reference Manual


Ends a timesharing job.




/FAST is an optional switch that prevents processing of your LOGOUT.CMD and the system's LOGOUT.CMD files.
n is an optional job number. Specify n only when logging out a job other than your attached job.


System Use Under Current Account

The system acknowledges a valid LOGOUT command by printing your job number, user name, current account, terminal number, and the current date and time. Then it shows the total amount of CPU time you used during the terminal session and the total length of time you were logged in, followed by the account of CPU time used under the current account and the length of time you were logged in under this account.


Before logging you out, the system processes the commands in your login directory's LOGOUT.CMD file and the system's LOGOUT.CMD file and displays any output from these commands. Then, after execution of each file, the system displays the message "End of LOGOUT.CMD", unless the last command in the file is a TAKE command.


Expunging Your Log-in and Connected Directories

Before logging you out, the system expunges any deleted files from your log-in and connected directories, and prints a message if either directory is still exceeding its assigned permanent disk quota.

Logging Out Other Jobs

By specifying a job number you can log out any other job logged in under the same user name as your attached job. A user with Wheel or Operator capabilities enabled can log out any job on the system. Whenever you log out another job, the system prints the job's user name, terminal number, and current program. You must then confirm the LOGOUT command with an extra RETURN.

When a job is logged out by another job, the logout command files are not processed.


A Final TAKE Command

To suppress the display of the message "End of LOGOUT.CMD" after execution of your LOGOUT.CMD file, make the last command in the file a TAKE command with no arguments. Be sure the file contains only one RETURN after the TAKE command.

Errors in LOGOUT.CMD

If there is an error in a command in your LOGOUT.CMD file, the system processes the commands up to the one in error and cancels the LOGOUT command. To log out, correct the error in the command file or give the LOGOUT command with the /FAST switch.

Effect on Memory and Terminal

The LOGOUT command clears memory and leaves your terminal in the state before log-in. LOGOUT n does not affect memory and leaves your terminal at TOPS-20 command level.
