 You can copy that text to new text file, then rename the text file to **something.bat** and move it to the folder where you want to process the files. Then just double click the **something.bat** and processing should start.

 ==== JS scripting (ECMAScript) only batch processing ====
 Since AVIdemux supports JS scripting (ECMAScript), you can create scripts with it also. These scripts can be loaded from command-line (**--run**) or from GUI (**File -> Load/Run project...**). Because environment is same on all platforms, the scripts are quite portable. Only problematic part is slashing since some operating systems assume **/** is the proper one and few systems think **\** is the right one.
-With JS scripts one can also use additional GUI elements (file folder select dialog) which helps if you must make newbie friendly scripts.

+You can create scripts quite easily by yourself. You can apply needed settings via GUI and then use **File -> Save Project As...** to create text file that contains all settings. Then you can open that file in text editor and copy+paste needed stuff to new script (or replaces parts of other script).
+==== Combination of command-line and JS scripting ====
+Last option is to combine best of both worlds. Usually the best situation for this is to create automated script (no dialogs) that you will run for all files.

+Win32 example (.bat file) that will convert all .mp4 files in current folder to .avi (XviD+MP3). Original files aren't modified. New files are named like **something.mp4.avi**
+<code>
+set avidemux="C:\Program Files\Avidemux 2.5\avidemux2.exe"
+for %%f in (*.mp4) do %avidemux% --force-alt-h264 --load "%%f" --run something.js --save "%%f.avi" --quit
+</code>
+For Linux/Unixes using Bash shell similar script would be
+<code bash>
+#!/bin/bash
+VAR="batchfiles.txt"
+ls *.mp4 | sort > $VAR # Collect the files in the current directory
+cat $VAR | while read line; do  # Loop read the filenames from the file
+  INPUT=$(echo ${line}) # Grab the next new filename
+  OUTPUT=${INPUT%.*4} # Remove shortest match of characters between the '. ' and the '4' at end of string
+  OUTPUT+=".avi" # Append new extension
+  avidemux2 --force-alt-h264 --load "$INPUT" --run something.js --save "$OUTPUT" --quit
+done
+rm $VAR # Remove the text file with the file names
+</code>
+(this will create **something.avi** from **something.mp4**)
+If you create your own combine batch settings, make sure order of command-line parameters is always --load something, --run something and --save something (AVIdemux will run these options in give order).
+==== Tips ====
+  * You can replace **avidemux2** with **avidemux2_cli** if you want to process files without GUI
+  * You can use **--nogui** option in case you want to suppress all dialogs (it must be first option!)
