BATCH FILE EXAMPLES
Here are example batch files. They will not be explained line by line, except for the more ambiguous ones. The title remarks should suffice so you'll understand their operation, although some will be preceded by a syntax example. Explanatory notes to the right are not part of the file. Do not type them in. For further explanation, see Batch File Basics, before reading this section.
The "DR" command is a batch file that runs an after-market directory program I use called Color Directory. It is used with the batch files here to confirm that an operation has happened. You may substitute DOS' "DIR" or "XDIR" command with its switches set to your preferences, or use any directory display program of your choosing.
Note that full paths to commands used in these batch files have not always been shown. This is to reduce confusion for batch-file newbies. To be fully efficient, any program called or run from a batch file should be preceded by its full path.
Be aware that Doctor DOS will not be responsible for any problems encountered through the use or mis-use of anything presented here.
An advisory to non-Canadians: Some characters shown in some batch
files here may not be able to be reproduced on your system unless
the Country Code is changed or you type them in as ASCII characters.
Consult your text editor/word processor manual to see how to do the latter.

This batch file uses the DOS "FOR-IN-DO" (FOR) command and replaceable parameters. Basically, it means "FOR each Item INside the Brackets, DO the given command". In this case, it will take each file name you give at the command line and substitute it for one of the percent-numbers. These percent-numbers are replaceable parameters, with "%1" representing the first file name, "%2, the second, and so on. Wild card characters, ` ? ' and ` * ', may be used in file names.
The batch file deletes each item inside the brackets, which will be those file names you typed at the command line. Each file name is substituted for one of the percent numbers. You may specify up to nine file names or groups.
:: MDEL.bat (Improved) :: Allows Deletion of Multiple Files :: with Different Names and Extensions @ECHO OFF CLS Clears the Screen. :AGAIN See Text. ECHO Deleting %1 DEL %1 SHIFT IF NOT "%1" == "" GOTO AGAIN ECHO. Adds a Blank Line to the Display. C:\BATCH\DR Confirms the Operation.
This version allows one to type as many file names as the command line can hold. It uses the "SHIFT" command. This permits each file name on the command line to move down one number to become the first replaceable parameter. Thus, the second file name will become "%1" after the SHIFT command is issued, the third file name becomes "%2", and so on. After yet another SHIFT command, the third file name will be in position "one" (%1). As long as there are file names left on the command line, they will be shifted one at a time into position number "one". Then, each is deleted in turn with an on-screen message to that effect being displayed. The "IF NOT..." statement says that as long as `%1' is not equal to nothing (that is, equal to something), the batch file is to return to the "AGAIN" label.
Finally, when no file names are left, the "IF NOT" statement becomes false because "%1" will by then actually be equal to nothing. Thus the batch file does not loop back up to "AGAIN" and instead goes on to display the directory listing confirming that the files are gone.
:: MU.bat (Move Up) :: Move All or Specified Files Up One Level :: @ECHO OFF If "%1" == "" GOTO MOVE-ALL If NOT "%1" == "" GOTO MOVE-SPEC :MOVE-ALL MOVE /-Y *.* .. GOTO END :MOVE-SPEC FOR %%F IN (%1 %2 %3 %4 %5 %6 %7 %8 %9) DO MOVE /-Y %%F .. :END ECHO. Adds a Blank Line to the Display. F:\BATCH\DR ________
This allows one to move up to nine files or file groups into the parent directory one level up. I use it because I have many directories in which there is a WORK subdirectory. After doing my work, I want to move the completed files into the parent directory and use this batch file to do so. The "/-Y" will prompt you if any files in the parent directory are about to be overwritten. You may choose to overwrite or not. The batch file will then resume and go on to the next file. (Be aware, some DOS versions do not recognise this switch and will overwrite without prompting.)
You may modify this batch file into CU.bat (Copy Up) by replacing the
MOVE commands with:
COPY *.* .. /-Y
COPY %%F .. /-Y .
Note that the "Overwrite" switch comes at the end of the line when COPY is used.
:: SDEL.bat (Safe Delete) :: Displays File to Be Deleted :: Prompts to Delete File or Abort Operation :: Wildcards May be Used to Delete File Groups :: @ECHO OFF CLS IF NOT "%1" == "" GOTO DISPLAY ECHO. IF "%1" == "" ECHO No File(s) Specified! Prompts if No File ECHO. is Given. GOTO END :DISPLAY ECHO %0 %1 Gives the Batch File Name ECHO. and File to be Deleted. ECHO These Files Will Be Deleted: ECHO. DIR %1 | FIND "Directory" Displays the Path and DIR %1 /B /P Files to be Deleted. ECHO. ECHO To Delete Listed Files, Allows the User to ECHO Press Any Key Continue or Abort. ECHO. ECHO To Cancel, Press: `Control-C' ECHO. PAUSE >: NUL :DELETE Deletes Selected File(s). DEL %1 ECHO. :END ECHO. Adds a Blank Line to the Display. C:\BATCH\DR Confirms the Operation.
An improved SDEL.bat may be found in Advanced Batch Files.
:: STEP.bat :: Allows one to Step through a Batch File :: To Test Each Line :: @ECHO OFF COMMAND /Y /C %1.bat %2 %3 %4 :END ________
This simple example allows one to run a batch file a line at a time to test it. It runs another copy of DOS' COMMAND.com. The "/Y" switch is what does the stepping. It displays each line and asks if you wish to run it or not by pressing "Y" or "N". You may exit this procedure at any time by pressing "CONTROL-C". Also, by pressing "Escape", the batch file will continue on its own from the current line.
The "/C" switch runs the specified command and then returns to the base COMMAND.com - either after the stepping procedure finishes, or after pressing "CONTROL-C".
When running this batch file, don't type the ".bat" extension. STEP.bat does that for you via the "%1.bat" replaceable parameter. If the batch file requires additional parameters, you may specify up to three via the " %2 %3 %4" replaceable parameters. Here's a syntax example:
STEP SDEL TEST.txt
This will step through the "SDEL" batch file using "TEST.txt" as SDEL's file parameter. (SDEL.bat was presented here as the previous example batch file.)
