Using SAFECOM in Execute-and-Quit Mode

If you need to enter only a few SAFECOM commands, you can use the execute-and-

quit mode from TACL. To run SAFECOM in this mode, type "SAFECOM," followed by

one or more security commands.

SAFECOM executes the commands and immediately returns control to TACL. If you

want to execute another SAFECOM command, you must begin that command by

retyping SAFECOM at the TACL prompt.

For example, assume user 3,7 is running TACL and wants to change the access

control list for the disk file named $data.sales.report6. The following commands display

the status of the protected disk file and grant READ authority to another user:

2> VOLUME $data.sales

3> SAFECOM INFO DISKFILE report6

4> SAFECOM ALTER DISKFILE report6, ACCESS mkt.jane READ

5> SAFECOM INFO DISKFILE report6

In this example, the TACL VOLUME command (prompt 2) establishes the default

volume and subvolume. (The current defaults are passed to SAFECOM when it is run.

SAFECOM then uses these default names to expand the partially qualified disk-file

name report6 to $data.sales.report6.)

The first SAFECOM command (prompt 3) requests an INFO report on the file

$data.sales.report6. After the access list for report6 is displayed, an ALTER DISKFILE

command adds a new access control list entry to grant READ authority to the local

user MKT.JANE, with user ID 33,104. The last SAFECOM command (INFO DISKFILE

at prompt 5) shows that the access control list for report6 was changed correctly.

For additional information about access control lists, see Section 3, Securing Disk

Files.

Using SAFECOM in Batch Mode

Batch mode is useful when you want to perform a number of security management

tasks more than once. To use SAFECOM in batch mode, you must first create an EDIT

file that contains the sequence of SAFECOM commands you want to execute. To
