That ssound like a good idea and close to what I want to achieve, but it
doesn't seem to work in XFCE. When I drop some a file on a desktop file
("starter") that is associated with my testdnd.sh script, the script
doesn't get any input:

----testdnd.sh----
#!/bin/bash

echo 'testdnd.sh'

echo 'First two arguments:'
echo -n '$1: '
echo $1
echo -n '$2: '
echo $2

echo 'Standard Input: '
while read line
do
  echo "$line"
done < "${VAR:-/dev/stdin}"

read
----end----

When I drag a text file on the starter / desktop file, the mouse cursor
displays a '+' Symbol, as if the starter accepts that file. But when I
drop it, I get neither parameters nor standard input (that's what I
expect).

----output----
testdnd.sh
First two arguments:
$1: 
$2: 
Standard Input: 
----end----

In contrast, when I call the script from the command line, it gives me
both, parameters and stdin:

----
$ cat test.txt | ./testdnd.sh a b
testdnd.sh
First two arguments:
$1: a
$2: b
Standard Input: 
This is
a multiline
text file

It doesn't work for me. Am I doing something wrong?

Anyway, this wouldn't be an optimal solution. In some cases I need to
pass multiple arguments in a specific order. For example an audio and
video file that should be combined into a single .mp4 file.
