bag-cat

Synopsis

bag-cat [OPTIONS] INPUT-FILE-OR--

Description

Like UNIX cat, the bag-cat program makes a stream of data available on its standard output stream. Unlike UNIX cat, the data is obtained by processing log files.

The usual RSB-related commandline options, IDL-related options and replay-related options are accepted.

Examples

  • $ bag-cat isr.tide | head
    <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 channels 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
