Extracting rows from a space delimited text file based on the values of a column
I have a space delimited text file. I want to extract rows where the third column has 0 as a value and write those rows into a new space delimited text file. How do I go about doing that? Thanks!

regexp::common::delimited5.18
Regexp::Common::delimited(3) User Contributed Perl Documentation Regexp::Common::delimited(3)
NAME
Regexp::Common::delimited -- provides a regex for delimited strings
SYNOPSIS
use Regexp::Common qw /delimited/;
while (<>) {
/$RE{delimited}{-delim=>'"'}/ and print 'a " delimited string';
/$RE{delimited}{-delim=>'/'}/ and print 'a / delimited string';
}
DESCRIPTION
Please consult the manual of Regexp::Common for a general description of the works of this interface.
Do not use this module directly, but load it via Regexp::Common.
$RE{delimited}{-delim}{-esc}
Returns a pattern that matches a single-character-delimited substring, with optional internal escaping of the delimiter.
When "-delim=S" is specified, each character in the sequence S is a possible delimiter. There is no default delimiter, so this flag must
always be specified.
If "-esc=S" is specified, each character in the sequence S is the delimiter for the corresponding character in the "-delim=S" list. The
default escape is backslash.
For example:
$RE{delimited}{-delim=>'"'} # match "a " delimited string"
$RE{delimited}{-delim=>'"'}{-esc=>'"'} # match "a "" delimited string"
$RE{delimited}{-delim=>'/'} # match /a / delimited string/
$RE{delimited}{-delim=>q{'"}} # match "string" or 'string'
Under "-keep" (See Regexp::Common):
$1 captures the entire match
$2 captures the opening delimiter (provided only one delimiter was specified)
$3 captures delimited portion of the string (provided only one delimiter was specified)
$4 captures the closing delimiter (provided only one delimiter was specified)
$RE{quoted}{-esc}
A synonym for $RE{delimited}{q{-delim='"`}{...}}
