Even in MS_DOS 6.22 days this was not a safe way. If you want to see, what is inside you just have to use dir and xcopy. Lets assume you are in parent directory of the alt-char named folder, TEST is an unused filename, and A is part of this alt-char named folder (verified using dir), then this is a ...

It is not recommended to do that using batch... . If you want a fast and secure way to do this i recommend you to learn c++ or something similar and some little bit about CRC32 and MD5. If you do that you are able to detect even small parts of files that had been corrupted. Also you need to read muc...

I fear it is not possible to send special keys via pipe using the cmd shell, or command.com environment. If nothing important was changed since MS-DOS 6.22, piped bytes with value 0x00 will be interpreted by set /p as an end of line. I assume nothing changed, because <nul set /p "=." still...

I had built in some errors, sry.
I have corrected the code above, hopefully it works now.

There are some errors. Here is a fixed version: @if (@X)==(@Y) @end /* harmless hybrid line that begins a JScrpt comment ::: Batch part :::: @echo off cscript //nologo //e:JScript "%~f0" %* exit /b *** JScript part ***/ var fso = new ActiveXObject("Scripting.FileSystemObject"); v...

The full code (Samir's algorithm), if robocopy could not be installed to the system you use: :main @echo off setlocal :: detect usb stick on assumtion: this batch is started from it. set "usbVolume=%~d0" set "usbVolume=%usbVolume:~0,1%" set "targetDirectory=\targetDirectory&...

I have not much time today (sry), so here only a little bit code to get all connected volumes to search for. Maybe wou want to remove some volumes, this can be done easiliy. See the example in the code: :main setlocal call :getConnectedVolumes connectedVolumes echo connectedVolumes: %connectedVolume...

I have renamed the test text file batman.txt to -åäö.txt and got no errors on execution on XP home and Win7 home, so i cannot fix it. The only problem i got is with the ampersand (&). I fixed it, maybe this helps you, too: @echo off cls setlocal set "combined=combined.txt" ( for %%a in...

I thought, I have tested that,... but i only tricked myself out when verifying it: Z:>echo hallo > aaaaaaaaaaaaaaaa512times_or_more:?* >> test.txt Z:>type test.txt Der Befehl "set"test=hallo"" ist entweder falsch geschrieben oder konnte nicht gefunden werden. But the content of t...

Case 1: echo %time% > filename > NUL The command processor (CP) executes this atomic expression: At first it redirects the streams by handles, and then executes the command. So if no error occurs the CP: 1. redirects the standard output stream (STDOUT) to a FileOutputStream (filename) (Wrong: See je...

Normally i using the executables without the path prior to it, too, but i then add the following at the beginning of a batch file and run it: @echo off setlocal for /f "tokens=2* delims=:" %%a in ('%SystemRoot%\system32\find /C "#" "%~f0"') do set /a "lines=%%b&quo...

Definitely that.
If you don't exactly specify which executable to run, someone may execute his exe file instead of yours, with your rights as you call it.

@probyn I've found an issue when executing: Z:\>SET TEST= test Z:\>SET TEST_A= test a Z:\>safeTrim TEST Z:\>SET TEST TEST=test a TEST_A= test a This could be fixed by adding a safe if "%1" == "TEST", also a %1 gatekeeper should be performed, so the whole code changes to: @echo of...

If source is a directory, and
destination is a directory too, or not existing, and
your batch is in the right directory,
then this code should work well.

Maybe you rem out the @echo off line, and see what error message will be displayed.

Is it any safer if we just pass the name of the variable whose value is to be trimmed rather than the value itself? Much better, i have tested all tricks, i remembered, on your safetrim.bat: @echo off set x=%1 for /f "tokens=1* delims==" %%a in ( 'set %1' do call :exec %%b goto :EOF :exec...
