The general options are not specific to any particular file and apply to the entire current run of the program. They are listed below.
For each data record, check for a match with each of the reference files. This option is set by default. When turned off with ‘--no-check-all-reference’, processing of that data file record will be stopped as soon as a required match is not fulfilled. This is a shortcut for speed, but it will change the meaning of any flags or counters set in reference-file-based input.
In any output based on a reference file, print a flag with the value ‘1’ if the record was matched by a data record or ‘0’ otherwise.
In any output based on a reference file, print a new field which is a count of the number of data records that matched the current reference record.
If counters or sums of data fields are being written into reference-based output, make them number bytes long.
At the end of the processing, write to
stderr counts of the
number of records read and matched from each file processed. The option
is enabled by default. When turned off with ‘--no-statistics’
print no statistics.
Write all the information that is possible about the processing to
stderr. This includes a summary of the options that have been
set and running counters of the number of records processed.
