batch processing: append (linux / windows)

[Jan Gruuthuse]

Linux:
sometimes the dialog window pops up, asking if files needs to append. There is an --append switch forcing appending of files. Can there be a provision for a --noappend to circumvent the append detection/question: yes/now? Or --append 0 for no appending action?

#!/bin/bash
for FIL in `ls *mp4 | sort` ; do
  /usr/bin/avidemux3_qt4 --force-alt-h264 --load "$FIL" --run /home/jan/mp4TOmkv.js --save ${FIL%.*}.mkv --quit
done

To "automate" the response to this dialog window pop-ups, I provided in the command line a redirection of StandardIn to a file (say: No.txt). the contents of that file is one single line = "no". This helped for me (my working environment is Windows, not Unix)

done
would reply no when input is expected.

If the question is not asked to autoload / append found video parts that look sequential, these methods would not work as there is no request for input.

Have not touched Unix for more than 20 years now, but I thought redirection of StandardIn would be something like this:

/usr/bin/avidemux3_qt4 --force-alt-h264 --load "$FIL" --run /home/jan/mp4TOmkv.js --save ${FIL%.*}.mkv --quit  <file_for_input_with_no_in_it

Please forgive if I am totally wrong.

yes n | / is not file redirection, it is command that inserts the option following yes.
I've read that sometimes redirection over StandardIn did not work, that was the reason for creation of yes command.
