Fsdb::Filter::dbcoldefine - define the columns of a plain text file to make it an Fsdb file
This program writes a new header before the data with the specified column names. It does *not* do any validation of the data contents; it is up to the user to verify that, other than the header, the input datastream is a correctly formatted Fsdb fil...

Fsdb::Filter::dbcoltype - define (or redefine) types for columns of an Fsdb file

Fsdb::Filter::dbfilealter - alter the format of an Fsdb file, changing the row/column separator
This program reformats a Fsdb file, altering the row ("-R rs") or column ("-F fs") separator. It verifies that this action does not violate the file constraints (for example, if spaces appear in data and the new format has space as a separator), and ...

Fsdb::Filter::tabdelim_to_db - convert tab-delimited data into fsdb
Converts a tab-delimited data stream to Fsdb format. The input is tab-delimited (*not* fsdb): the first row is taken to be the names of the columns; tabs separate columns. The output is a fsdb file with a proper header and a tab field-separator. This...

Fsdb::Filter::dbfilestripcomments - remove comments from a fsdb file
