How to add one file to multiple archives

[outbreak]

As the title says...

I have a bunch of .rar archives and now i need to add 1 file to each archive.
Now this wouldn't be a problem if i had 10-15 archives but i need to do this a bunch of times. So is there any "secret" option in winrar, or maybe some other application?

Thanks.

You will have to run a batch file.

Windows or linux?

Windows.

create a file raradd.bat or raradd.cmd depending on version of windows. Change the location of where the winrar is located depending on version of windows. Change the add.me file to the one you want added to the archive.
Place this file with the one you want added in the folder and run it.

@REM ------- BEGIN raradd.cmd ----------------
@setlocal
@echo off
set path="C:\Program Files (x86)\WinRAR\";%path%
for /F %%i in ('dir /s/b *.rar') do call :do_add "%%i"
goto :eof

:do_add
echo %1
rar a %1 add.me

:eof

REM ------- END raradd.cmd ------------------
