Hi Leon,

I've seen in the the ouput of cd-info this disc id.

But my issue is that the command cd-info takes a long time (some
seconds) to finish.

Now I use the output of cd-info  to generate an unique id for an audio cd.

But has to be done before the fs is mounted, causing extra delay.

I been looking for such an id (previous message on this list some
months ago), till I found this discid yesterday, and it's exactly what
I want. It generates an unique id, which has also some sense in the
cddb world, and this utility does it very fast!

So the point is, can cd-info give the same output, and also that fast as discid?

(the information is thus not only the hexnumber, but also, the number
of tracks, and the startsectors.. and total number of seconds)
