DBROWENUMERATE(1)

NAME
dbrowenumerate - enumerate rows, starting from zero

SYNOPSIS
dbrowenumerate

DESCRIPTION
Add a new column ``count'', incremented for each row of data, starting with zero. Use dbrowaccumulate for control over initial value or increment; this module is just a wrapper around that.

OPTIONS

-N or --new-name N
    Name the new column N. Defaults to "count".

This module also supports the standard jdb 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.

SAMPLE USAGE

  Input:
    #h account passwd uid gid fullname homedir shell
    johnh * 2274 134 John_Heidemann /home/johnh /bin/bash
    greg * 2275 134 Greg_Johnson /home/greg /bin/bash
    root * 0 0 Root /root /bin/bash
    # this is a simple database

  Command:
    cat DATA/passwd.jdb | dbrowenumerate

  Output:
    #h account passwd uid  gid fullname       homedir     shell     count
    johnh      *      2274 134 John_Heidemann /home/johnh /bin/bash 0
    greg       *      2275 134 Greg_Johnson   /home/greg  /bin/bash 1
    root       *      0    0   Root           /root       /bin/bash 2
    # this is a simple database
    #  | /home/johnh/BIN/DB/dbrowenumerate
