BATCH FILES IN THIS COLLECTION
Of the many batch files I have, I find I use these the most.
They will display their function and syntax if their names are
entered with no arguments.
COPY?.BAT
These copy a list of files from the current directory to
the drive that replaces the "?" in the file name.
DELX.BAT
Extends your DEL command to take a list of files to delete.
SHO.BAT
Feeds multiple files to SHOW.COM, one after the other.
DO.BAT
A generalization of the above. An alternative to the FOR
loop for doing multiple operations. Some operations are
much easier with DO, or possible only with DO. For example
to copy FILE1, FILE2, MY.FIL and LONGFILE.TXT from the
current directory to \TMP, enter:
DO copy \tmp FOR file? my.fil longfile.txt
Having said that, some operations are easier with the FOR
construct. In a sense DO turns the order of the normal
batch FOR and DO operators around and has a much easier
syntax.
HERE.BAT (Much improved version by Alan Dawson)
Marks your place in the disk for a quick return. Useful
when you are in some complex directory and want to go
elsewhere and return to it without typing some long
directory name.
Just say "HERE" to remember the current drive and
directory, and you can return to it with the "RET" command.
If you end your AUTOEXEC.BAT with
IF EXIST RET.BAT RET
then after any reboot you will wind up in the drive and
directory where you last said "HERE."
RET will also accept a command in the form RET COMMAND.
It will change to the directory and then execute the
command.
Examples: RET CLS, RET WP MYDOC
APATH.BAT
A simple path manipulator. APATH NEWDIRECTORY will
append NEWDIRECTORY to your path. APATH with no argument
will restore your original path. If a directory has
already been appended by APATH, the command APATH
NEWDIRECTORY will change the appended directory.
If your original path is
C:\WINDOWS;C:\DOS;C:\WP
then the command APATH C:\TMP will make it
C:\WINDOWS;C:\DOS;C:\WP;C:\TMP
If you now type APATH C:\TEST your path will become
C:\WINDOWS;C:\DOS;C:\WP;C:\TEST
If you type only APATH your path will be restored to
C:\WINDOWS;C:\DOS;C:\WP
It is instructive to trace this one with CMON. You'll see
how to make variants that prepend a directory, etc. (This
was actually an example made for a course some years ago.)
SOUNDS.BAT
Drives BEEPER.COM with "clip" sounds. See BEEPER.DOC.
COLORS.BAT
Shows ANSI color attributes. Useful with ESCAPE.COM.
(Needs ANSI.SYS or similar.)
