  <sr db_start="80" db_utt="80" />
  <sr db_start="45" db_utt="46" />
  <?xml version="1.0" encoding="UTF-8" standalone="no" ?><speech_hyp [...]
  <?xml version="1.0" encoding="UTF-8" standalone="no" ?><speech_hyp [...]
  <?xml version="1.0" encoding="UTF-8" standalone="no" ?><speech_hyp [...]
  <?xml version="1.0" encoding="UTF-8" standalone="no" ?><speech_hyp [...]
  <?xml version="1.0" encoding="UTF-8" standalone="no" ?><speech_hyp [...]
  <speech_hyp xmlns:bxml="http://www.sleepycat.com/2002/dbxml" [...]
  <TIMESTAMP>1290275288296</TIMESTAMP>
  

• $ bag-cat -c 'hyp' -c 'param' /tmp/nao.tide
  

  The above example prints the contents of all channel s matching one of the regular expressions hyp and param.

• $ bag-cat --style 'programmable/template :template "${create} ${data}\\n"' mydata.tide

Caveats

• Individual entries can no longer be distinguished (unless some in-band properties permit this)
• If multiple channels are printed, the channel from which a given part of the output originated is no longer apparent (unless some in-band properties allow determining this)
• Printing channels which contain binary content to a terminal may mess up the terminal and cause all sorts of mayhem
