KDESTROY(1)KDESTROY(1)NAMEkdestroy - destroy Kerberos tickets
SYNOPSISkdestroy [ -f ] [ -q ]
The kdestroy utility destroys the user's active Kerberos authorization
tickets by writing zeros to the file that contains them. If the ticket
file does not exist, kdestroy displays a message to that effect.
After overwriting the file, kdestroy removes the file from the system.
The utility displays a message indicating the success or failure of the
operation. If kdestroy is unable to destroy the ticket file, the util‐
ity will warn you by making your terminal beep.
In the Athena workstation environment, the toehold service automati‐
cally destroys your tickets when you end a workstation session. If
your site does not provide a similar ticket-destroying mechanism, you
can place the kdestroy command in your .logout file so that your tick‐
ets are destroyed automatically when you logout.
The options to kdestroy are as follows:
-fkdestroy runs without displaying the status message.
-qkdestroy will not make your terminal beep if it fails to destroy
KRBTKFILE environment variable if set, otherwise

Only the tickets in the user's current ticket file are destroyed. Sep‐
arate ticket files are used to hold root instance and password changing
tickets. These files should probably be destroyed too, or all of a
user's tickets kept in a single ticket file.
