+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

+  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
