How to display file transfer progress in percentage on the receiver and the transmitter?
ex.
dtn://node1 (sender)
dtnsend dtn://node2/sharebox  /home/user/file.pdf.tar

dtn://node2 (receiver)
dtninbox sharebox sharebox/

I try to make GUI file transfer with Qt framework (and its work) for simplify dtnsend command via terminal, can I use Linux terminal commands to display the percentage or for making the file transfer progress bar? Is there any other method rather than using dtnd -v command?
I would like to add those features on GUI file transfer.
