batch-fileDeprecated batch commands and their replacements

DEBUG

DEBUG command was used to create binaries/executabled from batch file. The command is still available in 32bit versions of windows , but is able to create binaries only with 16bit instructions with makes it unusable for 64bit machines. Now CERTUTIL is used for that purpose which allows to decode/encode binary/media files from HEX or BASE64 formats.Example with a file that creates icon file:

@echo off

del /q /f pointer.jpg >nul 2>nul
certutil -decode "%~f0" pointer.jpg
hh.exe pointer.jpg
exit /b %errorlevel%

Here's the same with hex format:

certutil -decodehex "pointer.hex" pointer.jpg

As you can see hex requires additional temp file and hex format expansions is bigger

APPEND

APPEND was command in msdos that allowed to use resource/media files like they are in the same directory.The command is still available in 32bit versions of windows but seems is not working. In some sources (including microsofts') it is pointed that the command is replaced by DPATH ,but it is not entirely true. Despite the DPATH help message points to APPEND command it's syntnax is the same as PATH.The directories listed in DPATH can be used with input redirection or type command :

@echo off
dpath %windir%

set /p var=<win.ini
echo using dpath with input redirection:
echo %var%
echo.
echo using dpath with type command:
type win.ini

BITSADMIN

BITSADMIN was used to transfer documents, download website, download files from websites, etc... This command is a deprecated command, and may be removed on next Windows updates. To prevent this issue, use the new Powershell BIT cmdlet.


Here is a sample code utilizing BITSADMIN.

@echo off
Bitsadmin /create /download Stackoverflow.com
rem download the website StackOverflow.com
