Fsdb::Filter::csv_to_db(3)

NAME
csv_to_db - convert comma-separated-value data into fsdb

SYNOPSIS
    csv_to_db <source.csv

DESCRIPTION
Converts a comma-separated-value data stream to Fsdb format.

The input is CSV-format (not fsdb). The first row is taken to be the names of the columns.

The output is two-space-separated fsdb. (Someday more general field separators should be supported.) Fsdb fields are normalized version of the CSV file: spaces are converted to single underscores.

OPTIONS

-F or --fs or --fieldseparator S
    Specify the field (column) separator as "S". See dbfilealter for valid field separators. Default is S (double space).

This module also supports the standard fsdb options:

-d  Enable debugging output.

-i or --input InputSource
    Read from InputSource, typically a file name, or "-" for standard input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

-o or --output OutputDestination
    Write to OutputDestination, typically a file name, or "-" for standard output, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

--autorun or --noautorun
    By default, programs process automatically, but Fsdb::Filter objects in Perl do not run until you invoke the run() method. The "--(no)autorun" option controls that behavior within Perl.

--help
    Show help.

--man
    Show full manual.
