I've already tried that solution, but the original .txt file wil be merged about every second.
If the second script is reading the line than runs the job and after that it makes a new .txt file, I'll lost some data from the original .txt file.

Maybe I can first copy the original file, than follow the script, and the next time I run the script I first have to merge the original file to the new file.

On this way it will work, but I rather have a "removeline" option or something like that.

Grttz...
