NAME

6       dbrowenumerate - enumerate rows, starting from zero
7

SYNOPSIS

9       dbrowenumerate
10

DESCRIPTION

12       Add a new column ``count'', incremented for each row of data, starting
13       with zero.  Use dbrowaccumulate for control over initial value or
14       increment; this module is just a wrapper around that.
15

OPTIONS

17       -N or --new-name N
18           Name the new column N.  Defaults to "count".
19
20       This module also supports the standard jdb options:
21
22       -d  Enable debugging output.
23
24       -i or --input InputSource
25           Read from InputSource, typically a file name, or "-" for standard
26           input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue
27           objects.
28
29       -o or --output OutputDestination
30           Write to OutputDestination, typically a file name, or "-" for
31           standard output, or (if in Perl) a IO::Handle, Fsdb::IO or
32           Fsdb::BoundedQueue objects.
33
34       --autorun or --noautorun
35           By default, programs process automatically, but Fsdb::Filter
36           objects in Perl do not run until you invoke the run() method.  The
37           "--(no)autorun" option controls that behavior within Perl.
38
39       --help
40           Show help.
41
42       --man
43           Show full manual.
