DIRCOMP Charles Petzold
Command 1987/No. 2 (Lab Notes)

______________________________________________________

Purpose: Permits comparison of the contents of two
directories in alphabetical order, with the
options of redirecting the screen display
either to a file or to a printer.

Format: DIRCOMP directory1 directory2

Remarks: The directories to be compared do not need to
be on the same drive. Use the normal DOS
backslash (\) character in specifying the
path to a desired directory. The DOS
"wildcard" characters (* and ?) may be used
to limit the filenames displayed.

Identically-named files are shown side-by-
side to facilitate comparison of their size,
date, and time. Other filenames are
presented alphabetically in their respective
directory columns. Use Ctrl-NumLock to halt
the display scrolling temporarily; striking
any key thereafter causes scrolling to
resume.

In comparing large directories it is
frequently desirable to redirect the output
of DIRCOMP either to a file (which you can
then call up with your word processor) or to
a printer.

Example: To create a file called COMPARE.TMP in the
root directory of drive C: (your currently
active drive) that compares the listings in
your \LETTERS subdirectory with the files
contained on a floppy disk in drive B: you
would enter:

DIRCOMP \LETTERS B: > \COMPARE.TMP

Example: To print out the same comparison without
creating a file, you would enter:

DIRCOMP \LETTERS B: > PRN

Notes:

1. DIRCOMP does not provide
forward/backward scrolling capabilities.
If these are desired as an alternative
to alphabetical listings, use
SCANDIR.COM, which is also contained on
this disk.
