In this example, the DEFINE/KEY command defines the PF3 key on the
keypad to perform the SHOW TIME command. DEFAULT refers to the default
state.
| #2 |
$ DEFINE/KEY PF1 "SHOW " /SET_STATE=GOLD/NOTERMINATE/ECHO
%DCL-I-DEFKEY, DEFAULT key PF1 has been defined
$ DEFINE/KEY PF1 " DEFAULT" /TERMINATE/IF_STATE=GOLD/ECHO
%DCL-I-DEFKEY, GOLD key PF1 has been defined
$ [PF1]
$ [PF1]
$ SHOW DEFAULT
DISK1:[JOHN.TEST]
|
In this example, the first DEFINE/KEY command defines the PF1 key to be
the string SHOW. The state is set to GOLD for the subsequent key. The
/NOTERMINATE qualifier instructs the system not to process the string
when the key is pressed. The second DEFINE/KEY command defines the use
of the PF1 key when the keypad is in the GOLD state. When the keypad is
in the GOLD state, pressing PF1 causes the current read to be
terminated.
If you press the PF1 key twice, the system displays and processes the
SHOW DEFAULT command.
The word DEFAULT in the second line of the example indicates that the
PF1 key has been defined in the default state. Note the space before
the word DEFAULT in the second DEFINE/KEY command. If the space is
omitted, the system fails to recognize DEFAULT as the keyword for the
SHOW command.
| #3 |
$ SET KEY/STATE=ONE
%DCL-I-SETKEY, keypad state has been set to ONE
$ DEFINE/KEY PF1 "ONE"
%DCL-I-DEFKEY, ONE key PF1 has been defined
$ DEFINE/KEY/IF_STATE=ONE PF1 "ONE"
%DCL-I-DEFKEY, ONE key PF1 has been defined
|
This example shows two ways to define the PF1 key to be "ONE"
for state ONE.
The second DEFINE/KEY command shows the preferred method for defining
keys. This method eliminates the possibility of error by specifying the
state in the same command as the key definition.
DELETE
Deletes one or more files from a mass storage disk volume.
Requires delete (D) access to the file and write (W) access to
the parent directory. If the target file is itself a directory, the
directory must be empty.
Format
DELETE filespec[,...]
Parameter
filespec[,...]
Specifies the names of one or more files to be deleted from a mass
storage disk volume. The first file specification must contain an
explicit or default directory specification plus an explicit file name,
file type, and version number. Subsequent file specifications need
contain only a version number; the defaults will come from the
preceding specification. The asterisk (*) and the percent sign (%)
wildcard characters can be used in any of the file specification fields.
If you omit the directory specification or device name, the current
default device and directory are assumed.
If the file specification contains a null version number (a semicolon
(;) followed by no file version number), a version number of 0, or one
or more spaces in the version number, the latest version of the file is
deleted.
To delete more than one file, separate the file specifications with
either commas (,) or plus signs (+).
Description
The DELETE command deletes one or more files from a mass storage disk
volume. This command requires delete (D) access to the file and write
(W) access to the parent directory. If the target file is itself a
directory, the directory must be empty.
Qualifiers
/BACKUP
Modifies the time value specified with the /BEFORE or the /SINCE
qualifier. The /BACKUP qualifier selects files according to the dates
of their most recent backups. This qualifier is incompatible with the
/CREATED, /EXPIRED, and /MODIFIED qualifiers, which also allow you to
select files according to time attributes. If you specify none of these
four time qualifiers, the default is the /CREATED qualifier.
/BEFORE[=time]
Selects only those files dated prior to the specified time. You can
specify time as absolute time, as a combination of absolute and delta
times, or as one of the following keywords: BOOT, LOGIN, TODAY
(default), TOMORROW, or YESTERDAY. Specify one of the following
qualifiers with the /BEFORE qualifier to indicate the time attribute to
be used as the basis for selection: /BACKUP, /CREATED (default),
/EXPIRED, or /MODIFIED.
For complete information on specifying time values, refer to the
OpenVMS User's Manual or the online help topic DCL_Tips (subtopic Date_Time).
/BITMAP n[,n,...] (Alpha only)
Enables the system manager to delete one or more active bitmaps to make
memory resources available. If a bitmap is deleted, then former virtual
unit members can be added only with a full copy operation.
Requires ownership of the device or VOLPRO protection.
For additional information on bitmaps, refer to HP Volume Shadowing for OpenVMS.
/BY_OWNER[=uic]
Selects only those files whose owner user identification code (UIC)
matches the specified owner UIC. The default UIC is that of the current
process.
Specify the UIC by using standard UIC format as described in the
HP OpenVMS Guide to System Security.
/CONFIRM
/NOCONFIRM (default)
Controls whether a request is issued before each delete operation to
confirm that the operation should be performed on that file. The
following responses are valid:
|
YES
|
NO
|
QUIT
|
|
TRUE
|
FALSE
|
Ctrl/Z
|
|
1
|
0
|
ALL
|
|
|
[Return]
|
|
You can use any combination of uppercase and lowercase letters for word
responses. Word responses can be abbreviated to one or more letters
(for example, T, TR, or TRU for TRUE), but these abbreviations must be
unique. Affirmative answers are YES, TRUE, and 1. Negative answers
include: NO, FALSE, 0, and pressing Return. Entering QUIT or pressing
Ctrl/Z indicates that you want to stop processing the command at that
point. When you respond by entering ALL, the command continues to
process, but no further prompts are given. If you type a response other
than one of those in the list, DCL issues an error message and
redisplays the prompt.
/CREATED (default)
Modifies the time value specified with the /BEFORE or the /SINCE
qualifier. The /CREATED qualifier selects files based on their dates of
creation. This qualifier is incompatible with the /BACKUP, /EXPIRED,
and /MODIFIED qualifiers, which also allow you to select files
according to time attributes. If you specify none of these four time
qualifiers, the default is the /CREATED qualifier.
/ERASE
/NOERASE (default)
When you delete a file, the area in which the file was stored is
returned to the system for future use. The data that was stored in that
location still exists in the system until new data is written over it.
When you specify the /ERASE qualifier, the storage location is
overwritten with a system specified pattern so that the data no longer
exists.
/EXCLUDE=(filespec[,...])
Excludes the specified files from the delete operation. You can include
a directory but not a device in the file specification. The asterisk
(*) and the percent sign (%) wildcard characters are allowed in the
file specification. However, you cannot use relative version numbers to
exclude a specific version. If you specify only one file, you can omit
the parentheses.
/EXPIRED
Modifies the time value specified with the /BEFORE or the /SINCE
qualifier. The /EXPIRED qualifier selects files according to their
expiration dates. (The expiration date is set with the SET
FILE/EXPIRATION_DATE command.) The /EXPIRED qualifier is incompatible
with the /BACKUP, /CREATED, and /MODIFIED qualifiers, which also allow
you to select files according to time attributes. If you specify none
of these four time qualifiers, the default is the /CREATED qualifier.
/IGNORE=INTERLOCK (Alpha only)
Allows you to mark a write-accessed file for deletion. This removes the
file name entry, and the file is deleted when it is closed by the final
user.
/LOG
/NOLOG (default)
Controls whether the DELETE command displays the file specification of
each file after its deletion.
/MODIFIED
Modifies the time value specified with the /BEFORE or the /SINCE
qualifier. The /MODIFIED qualifier selects files according to the dates
on which they were last modified. This qualifier is incompatible with
the /BACKUP, /CREATED, and /EXPIRED qualifiers, which also allow you to
select files according to time attributes. If you specify none of these
four time modifiers, the default is the /CREATED qualifier.
/SINCE[=time]
Selects only those files dated on or after the specified time. You can
specify time as absolute time, as a combination of absolute and delta
times, or as one of the following keywords: BOOT, LOGIN, TODAY
(default), TOMORROW, or YESTERDAY. Specify one of the following
qualifiers with the /SINCE qualifier to indicate the time attribute to
be used as the basis for selection: /BACKUP, /CREATED (default),
/EXPIRED, or /MODIFIED.
For complete information about specifying time values, refer to the
OpenVMS User's Manual or the online help topic DCL_Tips (subtopic Date_Time).
/STYLE=keyword
Specifies the file name format for display purposes while deleting
files.
The valid keywords for this qualifier are CONDENSED and EXPANDED.
Descriptions are as follows:
| Keyword |
Explanation |
|
CONDENSED (default)
|
Displays the file name representation of what is generated to fit into
a 255-length character string. This file name may contain a DID or a
FID in the file specification.
|
|
EXPANDED
|
Displays the file name representation of what is stored on disk. This
file name does not contain any DID or FID abbreviations.
|
The keywords CONDENSED and EXPANDED are mutually exclusive. This
qualifier specifies which file name format is displayed in the output
message, along with the confirmation if requested.
File errors are displayed with the CONDENSED file specification unless
the EXPANDED keyword is specified.
Refer to the OpenVMS User's Manual for more information.
Examples
The DELETE command deletes the file COMMON.SUM;2 from the current
default disk and directory.
The DELETE command deletes all versions of files with file type .OLD
from the default disk directory.
| #3 |
$ DELETE ALPHA.TXT;*, BETA;*, GAMMA;*
|
The DELETE command deletes all versions of the files ALPHA.TXT,
BETA.TXT, and GAMMA.TXT. The command uses the file type of the first
input file as a temporary default. Note, however, that some form of
version number (here specified as the asterisk (*) wildcards) must be
included in each file specification.
| #4 |
$ DELETE /BEFORE=15-APR/LOG *.DAT;*
%DELETE-I-FILDEL, DISK2:[MAIN]ASSIGN.DAT;1 deleted (5 block)
%DELETE-I-FILDEL, DISK2:[MAIN]BATCHAVE.DAT;3 deleted (4 blocks)
%DELETE-I-FILDEL, DISK2:[MAIN]BATCHAVE.DAT;2 deleted (4 blocks)
%DELETE-I-FILDEL, DISK2:[MAIN]BATCHAVE.DAT;1 deleted (4 blocks)
%DELETE-I-FILDEL, DISK2:[MAIN]CANCEL.DAT;1 deleted (2 blocks)
%DELETE-I-FILDEL, DISK2:[MAIN]DEFINE.DAT;1 deleted (3 blocks)
%DELETE-I-FILDEL, DISK2:[MAIN]EXIT.DAT;1 deleted (1 block)
%DELETE-I-TOTAL, 7 files deleted (23 blocks)
|
The DELETE command deletes all versions of all files with file type
.DAT that were either created or updated before April 15 of this year.
The /LOG qualifier not only displays the name of each file deleted, but
also the total number of files deleted.
The DELETE command deletes the file A.B with the highest version number.
| #6 |
$ DELETE/CONFIRM/SINCE=TODAY [MEIER.TESTFILES]*.OBJ;*
DISK0:[MEIER.TESTFILES]AVERAG.OBJ;1, delete? [N]:Y
DISK0:[MEIER.TESTFILES]SCANLINE.OBJ;4, delete? [N]:N
DISK0:[MEIER.TESTFILES]SCANLINE.OBJ;3, delete? [N]:N
DISK0:[MEIER.TESTFILES]SCANLINE.OBJ;2, delete? [N]:N
DISK0:[MEIER.TESTFILES]WEATHER.OBJ;3, delete? [N]:Y
|
The DELETE command examines all versions of files with file type .OBJ
in the subdirectory [MEIER.TESTFILES], and locates those that were
created or modified today. Before deleting each file, it requests
confirmation that the file should be deleted. The default
response---N---is given in brackets.
| #7 |
$ DIRECTORY [.SUBTEST]
%DIRECT-W-NOFILES, no files found
$ SET PROTECTION SUBTEST.DIR/PROTECTION=OWNER:D
$ DELETE SUBTEST.DIR;1
|
Before the directory file SUBTEST.DIR is deleted, the DIRECTORY command
is used to verify that there are no files cataloged in the directory.
The SET PROTECTION command redefines the protection for the directory
file so that it can be deleted; then the DELETE command deletes it.
| #8 |
$ DELETE DALLAS"THOMAS SECRET"::DISK0:[000,000]DECODE.LIS;1
|
This DELETE command deletes the file DECODE.LIS;1 from the directory
[000,000] on device DISK0 at remote node DALLAS. The user name and
password follow the remote node name.
| #9 |
$ DELETE NODE12::"DISK1:DEAL.BIG"
$ DELETE NODE12::DISK1:DEAL.BIG;
|
Either of these DELETE commands can be used to delete the file DEAL.BIG
on device ZZZ1 at remote node NODE12. Note that the DELETE command
requires an explicit version number in a file specification, but the
file to be deleted is on a remote node whose file syntax does not
recognize version numbers. (NODE12 is an RT-11 node.) Therefore, the
file specification must either be enclosed in quotation marks ("
") or entered with a null version number (that is, a trailing
semicolon [;]).
DELETE/CHARACTERISTIC
Deletes the definition of a queue characteristic previously established
with the DEFINE/CHARACTERISTIC command. The /CHARACTERISTIC qualifier
is required.
Requires OPER (operator) privilege.
Format
DELETE/CHARACTERISTIC characteristic-name
Parameter
characteristic-name
Specifies the name of the characteristic to be deleted.
Description
The DELETE/CHARACTERISTIC command deletes a characteristic from the
system characteristic table.
To modify a characteristic's name or number, you must delete and
redefine the characteristic.
Qualifier
/LOG
/NOLOG (default)
Controls whether the DELETE/CHARACTERISTIC command displays the name of
each characteristic after its deletion.
Example
|
$ DEFINE/CHARACTERISTIC BLUE 7
.
.
.
$ DELETE/CHARACTERISTIC BLUE
$ DEFINE/CHARACTERISTIC BLUE_INK 7
|
The DEFINE/CHARACTERISTIC command in this example establishes the
characteristic BLUE, with number 7, to mean blue ink ribbons for
printers. To change the name of the characteristic, enter the
DELETE/CHARACTERISTIC command. Then enter another DEFINE/CHARACTERISTIC
command to rename the characteristic to BLUE_INK, using the
characteristic number 7.
DELETE/ENTRY
Deletes one or more print or batch jobs. The jobs can be in progress or
waiting in the queue. The /ENTRY qualifier is required.
Requires manage (M) access to the queue, or delete (D) access
to the specified jobs.
Format
DELETE/ENTRY =(entry-number[,...]) [queue-name[:]]
Parameters
entry-number[,...]
Specifies the entry number (or a list of entry numbers) of jobs to be
deleted. If you specify only one entry number, you can omit the
parentheses. If you do not specify a queue name, you can delete entries
from multiple queues.
The system assigns a unique entry number to each queued print or batch
job in the system. By default, the PRINT and SUBMIT commands display
the entry number when they successfully queue a job for processing.
These commands also create or update the local symbol $ENTRY to reflect
the entry number of the most recently queued job. To find a job's entry
number, enter the SHOW ENTRY or SHOW QUEUE command.
queue-name[:]
Specifies the name of the queue where the jobs are located. The queue
name can refer either to the queue to which the job was submitted or to
the queue where the job is executing. The queue-name parameter
is optional syntax; however, when you specify a queue name, the
operating system uses it to verify an entry in the specific queue
before deleting the entry.
Description
The DELETE/ENTRY command deletes one or more jobs from a queue. If you
specify a queue name and more than one entry number with a DELETE/ENTRY
command, all the jobs must be located in the same queue.
You can delete jobs that are currently executing, as well as jobs that
are in other states. For example, DELETE/ENTRY can delete a job that is
currently in a holding or a pending state.
Qualifier
/LOG
/NOLOG (default)
Controls whether the DELETE/ENTRY command displays the entry number of
each batch or print job that it deletes.
Examples
| #1 |
$ PRINT/HOLD ALPHA.TXT
Job ALPHA (queue SYS$PRINT, entry 110) holding
.
.
.
$ DELETE/ENTRY=110 SYS$PRINT
|
The PRINT command in this example queues a copy of the file ALPHA.TXT
in a HOLD status, to defer its printing until a SET ENTRY/RELEASE
command is entered. The system displays the job name, the entry number,
the name of the queue in which the job was entered, and the status.
Later, the DELETE/ENTRY command requests that the entry be deleted from
the queue SYS$PRINT.
| #2 |
$ SUBMIT/AFTER=18:00 WEATHER
Job WEATHER (queue SYS$BATCH, entry 203) holding until 14-DEC-2001
18:00
$ SUBMIT/HOLD/PARAMETERS=SCANLINE DOFOR
Job DOFOR (queue SYS$BATCH, entry 210) holding
.
.
.
$ DELETE/ENTRY=(203,210)/LOG
%DELETE-W-SEARCHFAIL, error searching for 203
-JBC-E-NOSUCHENT, no such entry
%DELETE-I-DELETED, entry 210 aborting or deleted
|
The SUBMIT commands in this example queue the command procedures
WEATHER.COM and DOFOR.COM for processing as batch jobs. WEATHER.COM is
queued for execution after 6:00 P.M. DOFOR.COM is queued in a HOLD
status and cannot execute until you enter a SET ENTRY/RELEASE command.
Later, the DELETE/ENTRY/LOG command requests that the system delete
both these entries from the queue and display a message indicating that
the entries have been deleted.
The job WEATHER (entry 203) has completed by the time the
DELETE/ENTRY/LOG command is entered; therefore, entry 203 no longer
exists. Note that a message indicates that there is no entry 203 in the
queue. The job DOFOR (entry 210) is in a HOLD status when the
DELETE/ENTRY/LOG command is entered. Thus, the system deletes entry 210
from the queue and displays a message to that effect.
| #3 |
$ PRINT CHAPTER8.MEM
Job CHAPTER8 (queue SYS$PRINT, entry 25) pending on queue SYS$PRINT
.
.
.
$ SHOW QUEUE SYS$PRINT
Printer queue SYS$PRINT, on PARROT::PARROT$LPA0, mounted form DEFAULT
Entry Jobname Username Status
----- ------- -------- ------
24 CHAPTER7 SMITH Pending
25 CHAPTER8 SMITH Pending
$ DELETE/ENTRY=25 SYS$PRINT
|
The PRINT command in this example submits the file CHAPTER8.MEM to the
printer queue SYS$PRINT. Later, user SMITH needs to edit the file again
before printing it. Using the SHOW QUEUE command, SMITH verifies that
the job is still pending and that the entry number for the job is 25.
SMITH then enters the DELETE/ENTRY command to delete the job from the
queue.
DELETE/FORM
Deletes a form (for printer or terminal queues) previously established
with the DEFINE/FORM command. The /FORM qualifier is required.
Requires OPER (operator) privilege.
Format
DELETE/FORM form-name
Parameter
form-name
Specifies the name of the form to be deleted.
Description
The DELETE/FORM command deletes a form definition from the system forms
table. When you delete a form, there can be no outstanding references
to the form either in queues that have been mounted with the form or by
jobs requesting that form. To locate all references to the form, use
the SHOW QUEUE/FULL command.
To modify a form's name or number, you must delete and redefine the
form. Values for any DEFINE/FORM qualifier can be modified by
reentering the DEFINE/FORM command with different values, as long as
the form name and number remain the same.
Qualifier
/LOG
/NOLOG (default)
Controls whether the DELETE/FORM command displays the name of each form
after its deletion.
Examples
The DELETE/FORM command in this example deletes the form named CENTER.
| #2 |
$ DEFINE/FORM -
_$ /DESCRIPTION="letter size continuous form paper" CFLET 7
.
.
.
$ DELETE/FORM CFLET
$ DEFINE/FORM -
_$ /DESCRIPTION="letter size continuous form paper" LETTER_CONT 7
|
The DEFINE/FORM command in this example establishes the form CFLET with
number 7 to mean continuous-form paper 8.5 inches by 11 inches. To
change the name of the form, delete the form named CFLET and define a
new one named LETTER_CONT.
|
