PURGE Command
PURGE Command
Use the PURGE command to delete one or more disk files.
option
qualifies the purge operation. Specify option as one of these:
CONFIRM
specifies that TACL is to prompt for confirmation for each file, specified by
name or by matching a template, before purging the file.
NOCONFIRM
specifies that TACL is to purge the file without requesting confirmation. This
option is provided primarily for programmatic applications that do not need
confirmation of the purge operation.
file-name-template
is a file name or partial file name with wild-card characters. For more information
about file-name templates, see Section 2, Lexical Elements.
Considerations
These considerations apply to the PURGE command:
•
When you use the PURGE command to delete a disk file, the entry for the file is
deleted from the file directory in the volume where it resides, and any space
previously allocated to that file is made available to other files. Data in the file is not
physically deleted from the disk unless you specified the FUP CLEARONPURGE
option when you created the file. Files that are physically deleted are overwritten
with zeros. For information about the CLEARONPURGE option, see the File Utility
Program (FUP) Reference Manual.
•
You can purge a file only if it is not currently open; in addition, you must have
purge access to the file. See the description of the DEFAULT Program
on
page 8-53 for information about file-access restrictions.
•
If you try to use the PURGE command to delete a file that is being audited by the
TMF subsystem the attempt fails if there are pending transaction-mode records or
file locks; file-system error 12 (file in use) is returned. The purge is successful,
however, if the audited file is inactive.
These considerations apply to the use of the CONFIRM and NOCONFIRM options:
•
If you specify a file name with no wild-card characters and do not include
CONFIRM or NOCONFIRM, TACL does not display a confirm prompt.
