How to extract the line containg Duration only?

I want to extract the line Duration: 00:03:51.05, start: 0.025056, bitrate: 131 kb/s from output of ffprobe test.mp3.

ffprobe  test.mp3  |grep  Duration

All lines were output with my desired line, how to output my desired line only?

Solution

  • Replace | by 2>&1 | to redirect stderr to stdout.
