dbrowaccumulate [-C increment_constant] [-I initial_value] [-c increment_column] [-N new_column_name]

Compute a running sum over a column of data, or of a constant incremented per row, perhaps to generate a cumulative distribution.

What to accumulate is specified by -c or -C.

The new column is named by the -N argument, defaulting to accum.

-c or --column COLUMN

Accumulate values from the given COLUMN. No default.

-C or --constant K

Accumulate the given constant K for each row of input. No default.

-I or --initial-value I

Start accumulation at value I. Defaults to zero.

-N or --new-name N

Name the new column N. Defaults to accum.

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.
