[mad-user] Madplay capture output to file - how to?

[Gurpal S. Bhachu]

Hi,

I wish to capture the output of madplay to an external file eg:

$ madplay abc.mp3 -o abc.wav > abc.txt

It seems that abc.txt contains nothing! Is there some weird non standard
out thing happening here?
Please could someone advise how to do this...

Many thanks,
Gurpal

madplay is outputting on stderr instead of stdout. You can redirect stderr
to stdout with the directive '2>&1', so:
$ madplay abc.mp3 -o abc.wav 2>&1 > abc.txt
will work.
Or you can direct stderr directly to abc.txt:
$ madplay abc.mp3 -o abc.wav 2>abc.txt

This is quite useful for other console programs that output on stderr.
