EXCHANGE DELETE — VMS 5.5-2H4
Deletes one or more files from a foreign block-addressable mass
storage volume. EXCHANGE does not delete files from Files-11 volumes.
Format
EXCHANGE> DELETE file-spec[,...]
Prompt
Filename(s): file-spec[,...]
Additional information available:
Parameters
file-spec[,...]
Specifies the names of one or more files to be deleted. You can
specify wild card characters in any of the file specification
fields.
To delete more than one file, separate the file specifications
with commas (,) or plus signs (+).
RT-11 recognizes two file extensions (types) as having special
significance, and EXCHANGE mimics the special actions that RT-11
takes with respect to these files. The first of these specail
files is a file with an extension of ".SYS". EXCHANGE> DELETE
does not delete a file with an extension of .SYS unless the
/SYSTEM qualifier is present. EXCHANGE will print a message if
one or more .SYS files are passed over during a delete operation.
The second special file type is ".BAD". EXCHANGE does not delete
.BAD files if the file specification contains wildcards. A .BAD
file may be deleted by explicitly specifying its name. EXCHANGE
does not warn that .BAD files have not been deleted.
Qualifiers
Additional information available:
/LOG
/LOG
/NOLOG
Controls whether the EXCHANGE DELETE command displays the file
specification of each file after its deletion.
By default, the DELETE command does not display the names of
files after it deletes them.
/SYSTEM
/SYSTEM
/NOSYSTEM
Controls whether the EXCHANGE DELETE command deletes files which
have a file extension of ".SYS". These files are typically files
which are necessary for the operation of an RT-11 system. Only
RT-11 volumes treat .SYS files in this special manner.
By default, the DELETE command will not delete an RT-11 file with
a .SYS extension, whether it is matched by a wildcard spec or
explicitly named. EXCHANGE will print a message whenever it
skips over a .SYS file during a delete operation.
EXCHANGE also treats files with ".BAD" extensions as special, but
the /SYSTEM qualifier does not affect the operations against .BAD
files. To delete a .BAD file, specify the filename explicitly,
rather than using wildcards. EXCHANGE does not warn that .BAD
files are being skipped.
/VOLUME_FORMAT
/VOLUME_FORMAT=option
The /VOLUME_FORMAT qualifier defines the physical format of the
volume to be processed. RT-11 volumes are currently the only
volumes on which DELETE is supported. See section 6.0 for a
complete description of the /VOLUME_FORMAT qualifier and the
defaults.
Examples
1. EXCHANGE> DELETE DMA0:COMMON.SUM
The DELETE command deletes the file COMMON.SUM from the
RT-11 device DMA0:.
2. EXCHANGE> DELETE DXA0:*.OLD/LOG

file types of OLD from the floppy diskette. EXCHANGE
will log the name of each file deleted.
3. EXCHANGE> MOUNT /VIRTUAL TEST: TEST.DSK
EXCHANGE> DELETE TEST:ALPHA.TXT,BETA.TXT
The DELETE command deletes the files ALPHA.TXT and
BETA.TXT from the virtual-device file TEST.DSK.
