Using FUP for Basic File Management
This section describes using the File Utility Program (FUP) for basic disk file
management:
For more information about FUP, including the command syntax, see the File Utility
Program (FUP) Reference Manual.
Who Uses FUP?
Anyone who can log on to the TACL program can use FUP. Although most FUP
commands are available to all users, the system enforces security requirements for
accessing or altering files. For example, you cannot PURGE a file with FUP unless you
have purge access to that file, and you cannot LICENSE a program file that contains
privileged code unless you are logged on as the super ID (user ID 255,255). For more
information about security, see Section 16, Managing Users and Security
.
You can enter FUP commands at the TACL prompt, interactively through FUP itself, or
through a command file. You can also programmatically execute some commands from
an application. These commands use Subsystem Programmatic Interface (SPI) buffers
and procedures for the FUP commands and responses. See the File Utility Program
(FUP) Management Programming Manual for details.
Before you use FUP to create or manage disk files, you should be familiar with the
Compaq NonStop™ Kernel operating system concept of a file for the Guardian
operating system as described in Section 3, Managing Files With TACL
.
