how to use attachment file as a script argument

how to use attachment file as a script argument

[Bill Long]

based on the example of use mplayer play the movie, I write down
sthing like

>\defineprogram[sample.data][sample.data.sh]
>\goto{\externalfigure[sample.data][width=0.48\textwidth]}[program(sample.data{})]

and the content of  sample.data.sh  is

>#!/bin/bash
> FILE=$(basename "$0"); gnome-terminal -e "cat ${FILE/.sh/}"

it does work, but I wanna know if there are better way to
make this. as this way has some obvious problem:
  
 1. if I send this pdf file to other guy, the script won't  execute, as it
 can't find out the sample.data file. same thing will happen if I move
 my sample.data to other directory.

 2. it's take too much effort if I have lots of file to analysis, I
 have to write lots of file like sample.data1.sh,
 sample.data2.sh... with same content, soft link maybe a solution, but
 I hope there are more easy solution.
