flac dev - Sep 2004 - command-line flac tool to report song length?

I've got a bunch of flac files and need to report their length.

With MP3s, you use `mp3info -x $filename`

But is there a way to find out the length (minutes:seconds or just seconds) of a
flac audio file, without converting it to WAV first?

Thanks!

You can probably do this with shntool:

Hi Derek,

If you are on a system that has "tr", "awk", and pipelines,
the following
should give you the duration in seconds:

metaflac --show-total-samples --show-sample-rate foo.flac | tr '\n'
' ' | awk '{print $1/$2}' -

One way is to use the output from `metaflac' with the options
`--show-sample-rate' and `--show-total-samples'.

You can get this indirectly from metaflac by calculating it from the sample
rate, channels and total samples.  It could presumably be enhanced to
calculate it into a nicely-formatted time display.
