winrar command line to unarchive stuff

Tutorial - Using WinRAR command-line tools

When you install WinRar, two command-line tools are also installed, rar.exe and unrar.exe. They will be located in C:Program FilesWinRAR by default.

Here's an example of how to extract the contents of a single rar file:

open a command prompt

(Windows 2000/xp, choose start->programs->accessories->Command Prompt)
add the winrar tools to the path:

c:> set path="C:Program FilesWinRAR";%path%
switch to the directory where you want your files to extract to:

c:> cd /d z:some_folder
use unrar to extract the file:
z:some_folder> unrar e c:some_rar_file.rar

You can of course wrap all of this into a batch file that loops through all of the .rar files in a folder. Here's a quicky sample (doesn't handle spaces in .rar file names):

      @REM ------- BEGIN demo.cmd ----------------

      @setlocal

      @echo off

      set path="C:Program FilesWinRAR";%path%

      for /F %%i in ('dir /s/b *.rar') do call :do_extract "%%i"

      goto :eof

      :do_extract

      echo %1

      mkdir %~1.extracted

      pushd %~1.extracted

      unrar e %1

      popd

      REM ------- END demo.cmd ------------------

For detailed information on windows batch files, please see:

OSX documentation [new]

Open a terminal window.
In the terminal window, navigate to the folder containing your .rar files:

cd /<path-to-files>
Run the following command:
for i in *.rar; do unrar e "$i"; done
Note: "unrar" may need to be replaced with the full path to your unrar executable. For example, if unrar is installed in /usr/local/bin, the command becomes:
for i in *.rar; do /usr/local/bin/unrar e "$i"; done

OSX unrar is available from RAR Labs, here
