TABER CSC135 Lab 4.19: Show Commands
Name:



In this lab you will look at some information stored by the computer for its ow operation. This lab focuses on the show terminal command. This is just the-tip-of-the-iceberg. The VAX/VMS system has about 33 different show commands. These are listed: 
ACCOUNTING  ACL         AUDIT        BROADCAST    
CLUSTER     CPU         DEFAULT      DEVICES      
DISPLAY     ENTRY       ERROR        INTRUSION   
KEY         LICENSE     LOGICAL      MAGTAPE     
MEMORY      NETWORK     PRINTER      PROCESS   
PROTECTION  QUEUE       QUOTA        RMS_DEFAULT  
STATUS      SYMBOL      SYSTEM       TERMINAL     
TIME        TRANSLATION USERS        WORKING_SET 
ZONE
Take the time to look around at some of the other available information. On the VAX/VMS system most of this information can be accessed with the show command. If you have the correct permissions and authority you can change most of the values with the set command.

Fill in the answers to the questions in the space provided. You can copy this lab before turning it in if you want to keep your original.
