count_records count the number of records in the stream and outputs the count as a
record who's count is not included. Using count_recrods with the -x switch is
a lot faster because this prevents the need for parsing and emitting the records.
... | count_records [options]
[-? | --help] # Print full usage description.
[-x | --no_stream] # Do not emit records.
[-o <file> | --data_out=<file>] # Write result to file.
[-I <file!> | --stream_in=<file!>] # Read input from stream file - Default=STDIN
[-O <file> | --stream_out=<file>] # Write output to stream file - Default=STDOUT
[-v | --verbose] # Verbose output.
To count the records in the stream and saving the result to file, do:
... | count_record -o <file>
The resulting file will then contain some thing like this:
RECORDS_COUNT: 1234
