Question

I’m trying to capture dvdauthor’s output to a file.
So far i found this command but it’s not working:S

dvdauthor -x dvdauthor.xml > output.txt

Any kind of idea is really appreciated.

Answer 1

It looks as though dvdauthor prints a lot of output to stderr rather than stdout. I don’t have this software myself and so can’t be sure but I see a lot of this in (what I presume to be) the source code, which suggests that it’s printing informational messages to stderr rather than stdout:

fprintf(stderr, "INFO: dvdauthor creating table of contents\n");

The > redirect will only redirect stdout to file. To redirect stderr to file, you can use ‘2>’

Try:

dvdauthor -x dvdauthor.xml 2> output.txt
