What is PDELETE
---------------
PDELETE is an advanced Delete command to be used in DOS operating
systems. It may be used in place of the DOS Erase and Delete
command or instead of it. Like other Patriquin utilities, PDELETE
gives you more control of command processing and provides a much
safer way to process files. PDELETE also provides several
features not found with the standard DOS command.
Unlike other delete utilities, PDELETE does support DOS paths and
wildcards. It keeps you aware of what files are being processed
and provides an emergency stop feature just in case you have
started something you feel is wrong.
PDELETE's file selection parameters provide you with numerous
options for specifying the files to be deleted. You may select by
directory, file, date, attribute, size, and even starting and
ending filename.
PDEL Users Guide/Reference Copyright 1989 N. Patriquin Page 2
----------------------------------------------------------------------
Features:
---------
** Advanced file selection
** Emergency STOP by pressing any key
** Delete entire directories and remove them from disk
** Optionally wipe file data from disk during delete to
prevent it from being recovered by unauthorized
person.
** Optional verify feature lets you approve each file
before it is deleted
** Optionally deletes HIDDEN / SYSTEM / READONLY files
** Delete files until specified freespace is available
PDEL Users Guide/Reference Copyright 1989 N. Patriquin Page 3
----------------------------------------------------------------------
Command Parameters
------------------
PDELETE allows several command parameter switches to be specified
to customize the process. All these parameters are optional.
The command format and switch parameters are described below. A
quick review of command parameters is always available by
entering the PDEL command with no parameters.
COMMAND FORMAT:
PDEL filespec [ (/ switches) ]
filespec Enter a DOS file specification. Pathnames and
standard DOS wildcard characters are allowed.
Special pattern selection like *DISK*.* may be specified.
*DISK*.* would select all files that have the chars
'DISK' anywhere in the first portion of the filename.
*DI*S*K*.* type specification also works.
/A Archive - Selects only files that have been marked
updated by DOS. This flag is updated by DOS whenever
a files is processed with an intent to change or
create new data.
/BA Batch file processing. PDEL always check to determine if the
user has pressed a key to pause processing. This check
can interfere with programs that store keystrokes in the
keyboard buffer for subsequent processing. The /BA parameter
sets no-windows mode and disables the key press check to leave
stored keystrokes undisturbed.
/BW Forces PDEL to use monochrome colors even when it detects a
color display environment. (Black & White)
/C Overrides /NC when /NC is placed in the DOS environment
variable. /C indicates to ask before deleting any files
if a file pattern of *.* is specified.
PDEL Users Guide/Reference Copyright 1989 N. Patriquin Page 4
----------------------------------------------------------------------
/C2 /C3
Specify /C2 or /C3 to display the window processing screen in
an alternative color scheme. To make this color change
permanent, specify the parameter in the DOS environment
variable.
/D:[(]xxx Date. Select files based on the relationship between
[)] their last update date and the date specified. This
[=] parameter includes a date or number of days value.
It may also contain a modifier that reverses or
modifies the use of the date specified.
When xxx contains a date the date is compared to the
last update date of the file. The last update date
of the file is the date contained in its directory
entry. The file is selected if the condition specified
by the condition modifier is met. The condition
modifier meanings are:
'(' = Select files whose date is older than the
date specified.
')' = Select files whose date is newer than the
date specified.
'=' = Select files whose date is equal to the date
specified.
If the condition modifier is not specified, ')' is
assumed.
Date values may be specified in any of the following
formats:
MM/DD/YY MM-DD-YY DDMMMYY
12/31/80 12-31-80 31DEC80
If xxx contains a numeric value, that positive number
is used to calculate a date value a number of days
prior to the current date. Then that date is used
as in the calculation above.
PDEL Users Guide/Reference Copyright 1989 N. Patriquin Page 5
----------------------------------------------------------------------
Example:
/D:(1JAN86 - Process files updated before 1JAN86
/D:)1JAN86 - Process files updated after 1JAN86
/D:=1JAN86 - Process files updated 1JAN86
/D:(5 - Process files modified prior to 5 days ago
/D:)5 - Process files modified within the last 5 days
/D:=5 - Process files modified 5 days ago
/DI Delete the disk DIrectory specified in the command.
This will remove the directory, all files within
it and all the directories and files subordinate
to it.
Only use this as a stand alone parameter. Use a
command like the following one to remove a directory
from your disk:
PDEL \OLDDIR /DI PDEL *.*/DI
-- or --
PDEL \OLDDIR\*.* /DI
/EX Exit PDEL without user intervention. Before PDEL exits
window operation, it requests you to press any key.
This parameter bypasses this request so you can use
PDEL in DOS batch files.
/F:file First. Indicates that processing is not to start until
the specified full filename is encountered in the
scan of the directory.
/FS:nnnn Freespace. PDELETE will delete files as long as
there is less than nnnn thousand (nnnn * 000)
of free space available on the disk. This is very
helpful for cleaning up disks but retaining as many
files as possible.
PDEL Users Guide/Reference Copyright 1989 N. Patriquin Page 6
----------------------------------------------------------------------
/L:file Last. Indicates that processing is to stop after
the specified full filename is encountered in the
scan of the directory. The file specified will be
processed if it matches selection criteria.
/M Stop screen from scrolling from scrolling past the end
without user intervention (MORE).
/N Do not display output in color
/NC PDELETE asks "Are you Sure?" when you request files
to be deleted with "*.*" patterns. To ignore this
question specify /NC. Place this in the DOS environment
variable with SET PDEL=/NC to prevent PDEL from
ever asking if you are sure.
/NT Prevent ending statistics about freespace and files
deleting from printing.
/NS sets all sounds generated to the speaker OFF.
(No Sound)
/NW No Windows - Do not use windows during processing. All screen
output will be done through standard DOS facilities.
/O Indicates that all filenames except those matching
the filename specified on the input command are to
be selected for processing.
/P Pause before each file is updated to allow user
to approve or reject the action for each file.
/RO Include files marked with DOS readonly attribute.
PDEL Users Guide/Reference Copyright 1989 N. Patriquin Page 7
----------------------------------------------------------------------
/S System -- If a source directory is supplied, that
directory and all subordinate directories will be
processed. If no source directory is specified,
all directories on the disk will be processed.
/SH Include files marked with DOS Hidden attribute. Normally
PDELETE will bypass these files.
/SF Include files marked with DOS System attribute.
/SZ: [(] [)] nnn Select a file based on its size. The
left paren indicates that files less than the
indicated size are to be selected. The right
paren indicates to select files greater than the
size. If right or left paren are not specified,
a left paren is assumed. Following are examples.
/SZ:100 -- Select files less than 100 characters
/SZ:(100 -- Select files less than 100 characters
/SZ:)100 -- Select files greater than 100 characters
/T Test the command. Use this switch when you
would like to test the command entered without
actually updating any files.
/TF Like test but after test operation is complete you will
be asked if delete is actually to be done. (Test First)
/WI For data security, erase all disk areas that
contain the file when it is deleted. This
will prevent unauthorized users from
recovering the file or examining its data
by using special disk utilities.
/W Force window operation. Used when you have /NW specified
in the DOS environment. This overrides /NW.
/WH PDELETE will indicate to you WHy files did not get
processed. Normally PDELETE will not tell you why or
when if a file is bypassed.
PDEL Users Guide/Reference Copyright 1989 N. Patriquin Page 8
----------------------------------------------------------------------
Examples:
---------
Delete all *.BAK files on current default drive
PDEL *.BAK /S
Delete all *.BAK files over 30 days old
PDEL *.BAK /S/D:(30
Remove directory \ACCTING1 from drive a:
PDEL A:\ACCTING1 /DI
