DBROWENUMERATE(1)

🎀 NAME 🎀

Okay so dbrowenumerate — straight from the User Contributed Perl Documentation crew — is here to enumerate rows, starting from zero. That’s it, that’s the job, and it slays at it 💅

✨ SYNOPSIS ✨

dbrowenumerate

💖 DESCRIPTION 💖

Add a new column "count", incremented for each row of data, starting with zero. If you want control over the initial value or the increment, use dbrowaccumulate — this module is just a wrapper around that. No cap, it’s a tiny icon. 🫶

🌸 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
