tcprobe+grep+cut

Axion · 08-23-2004, 12:47 PM

I am trying to grep/cut output from tcprobe in order to have only the framerate. i am able to do so fine to get the video length like this:

tcprobe -i /dev/dvd 2>&1 -T "1" | grep "playback" | cut -d " " -f 5
>> 00:00:28.29

but any attempt to cut the following grep results in no output whatsoever:

tcprobe -i /dev/dvd 2>&1 -T "1" | grep "rate"
>> frame rate: -f 23.976 [25.000] frc=1 (*)

I would like to have just "23.976" in the end but i cant cut it :/

Any help appreciated....thanks

Well, unless there's something you haven't mentioned, this worked for me:

t='frame rate: -f 23.976 [25.000] frc=1 (*)'
echo $t | cut -d' ' -f4
output was: 23.976

I don't have tcprobe, so I couldn't do it from scratch....
