SWEEP Charles Petzold
Command PC Magazine Vol 4, No 23
Copyright 1985 Ziff-Davis Publishing Company
______________________________________________________
Purpose: Causes a command to be successively executed
in every subdirectory on a hard disk.
Format: SWEEP Command [parameter(s)]
Remarks: SWEEP starts from the current directory. In
order to use SWEEP to extend the range of a
command to all the subdirectories on a disk,
use CD (if necessary) to make the root
directory your current directory. From the
root directory, the command
SWEEP DIR
will display the listings, by subdirectory,
of every non-hidden file on the disk. To
erase all the .BAK files on a disk you need
only get into the root directory and issue
the command
SWEEP DEL *.BAK
SWEEP itself will not accept parameters other
than its command. Thus, if you are on drive
C: and wish a directory of all files on drive
D: to be sent to your printer, you must first
make drive D: the current drive before you
issue the command
SWEEP DIR > LPT1
(In this case you would either need a copy of
SWEEP.COM on drive D: or else drive D: would
have to be listed on your PATH.)
SWEEP can execute .BAT file commands (and
even non-DOS commands, such as LOCATE.COM).
A useful file called CLEAN.BAT might consist
of the three lines
DEL *.BAK
DEL *.TMP
DEL *.OBJ
From the root directory, if you then enter
SWEEP CLEAN
all .BAK, .TMP, and .OBJ files will be erased
from the disk.
Notes:
1. Requires DOS 2.0 or later.
