How to bulk-extract objects from swf (Adobe Flash) files with swfextract?

swftools are a unique set of tools but lack some user friendliness. They can't even iterate over provided objects:

Only one file allowed. You supplied at least two.

$ swfextract file.swf -i 1,2

warning! You should use the -P when extracting multiple objects



$ ls

file.swf  output.swf



$ swfextract file.swf -i 1,2 -P



$ ls

file.swf  output.swf

Here is a bash script to automate it:

#!/bin/bash

find_ext=".swf"

out_ext=".jpg"



[ "$1" == "" ] && echo "Add type arguments from swfextract: -j -p -f -F -m -i" && exit 1 



for arg in $@; do

    for file in `find . -name "*$find_ext"`; do 

    ids="`swfextract $file | grep "[$arg]" | sed 's#^.*ID(s) ##g' |  sed 's#, # #g'`"

        for id in $ids; do

            swfextract "$file" $arg $id -o "${file}_${id}${out_ext}"

        done

    done

done

Don't forget to check the *_ext variables.
Feel free to improve the script by adding extensions automatically.
