First, thanks for the help in previous posts... couldn't have gotten where I am now without it!
So here is what I have, I use AWK to match $1 and $2 as 1 string in file1 to $1 and $2 as 1 string in file2. Now I'm wondering if I can extend this AWK command to incorporate the following:

I have the below 2 files:
1) Third field from file1.txt should be compared to the first field of lookup.txt.
2) If match found then third field, file1.txt should be substituted with the second field from lookup.txt.
3)Else just print the line from file1.txt.
File1.txt:... (4 Replies)
If $1 in file1 matches $2 in file2. Then the value in $2 of file2 is updated to $1"."$2 of file2. The awk seems to only match the two files but not update. Thank you :).

I am trying to look for $2 of file1 (skipping the header) in $2 of file2 (skipping the header) and if they match and the value in $10 is > 30 and $11 is > 49, then print the line from file1 to a output file. If no match is foung the line is not printed. Both the input and output are tab-delimited.... (3 Replies)
I am trying to use awk to match two files that are tab-delimited. When a match is found between file1 $1 and file2 $4, $4 in file2 is updated using the $2 value in file1. If no match is found then the next line is processed. Thank you :).

Hi All,
Greetings!
I have a file of 40000+ lines with different entries, I need matching entries filterd out to their files based on first filed pattern for the matching :
For example:
All server1 entries (in field1) to come together with its path in 2nd field.

In the perl below I am trying to set/update the value of $14 (last field) in file2, using the matching NM_ in $12
or $9 in file2 with the NM_ in $2 of file1.
The lengths of $9 and $12 can be variable but what is consistent is the start pattern will always be NM_ and the end pattern is always

WWW::RobotsRules - Parse robots.txt files
SYNOPSIS
require WWW::RobotRules;
my $robotsrules = new WWW::RobotRules 'MOMspider/1.0';
use LWP::Simple qw(get);
$url = "http://some.place/robots.txt";
my $robots_txt = get $url;
$robotsrules->parse($url, $robots_txt);
$url = "http://some.other.place/robots.txt";
my $robots_txt = get $url;
$robotsrules->parse($url, $robots_txt);
# Now we are able to check if a URL is valid for those servers that
# we have obtained and parsed "robots.txt" files for.
if($robotsrules->allowed($url)) {
$c = get $url;
...
}
DESCRIPTION
This module parses a /robots.txt file as specified in "A Standard for Robot Exclusion", described in
<http://info.webcrawler.com/mak/projects/robots/norobots.html> Webmasters can use the /robots.txt file to disallow conforming robots access
to parts of their web site.
The parsed file is kept in the WWW::RobotRules object, and this object provides methods to check if access to a given URL is prohibited.
The same WWW::RobotRules object can parse multiple /robots.txt files.
The following methods are provided:
$rules = WWW::RobotRules->new($robot_name)
This is the constructor for WWW::RobotRules objects. The first argument given to new() is the name of the robot.
$rules->parse($robot_txt_url, $content, $fresh_until)
The parse() method takes as arguments the URL that was used to retrieve the /robots.txt file, and the contents of the file.
$rules->allowed($uri)
Returns TRUE if this robot is allowed to retrieve this URL.
$rules->agent([$name])
Get/set the agent name. NOTE: Changing the agent name will clear the robots.txt rules and expire times out of the cache.
ROBOTS.TXT
The format and semantics of the "/robots.txt" file are as follows (this is an edited abstract of
<http://info.webcrawler.com/mak/projects/robots/norobots.html>):
The file consists of one or more records separated by one or more blank lines. Each record contains lines of the form
<field-name>: <value>
The field name is case insensitive. Text after the '#' character on a line is ignored during parsing. This is used for comments. The
following <field-names> can be used:
User-Agent
The value of this field is the name of the robot the record is describing access policy for. If more than one User-Agent field is
present the record describes an identical access policy for more than one robot. At least one field needs to be present per record. If
the value is '*', the record describes the default access policy for any robot that has not not matched any of the other records.
Disallow
The value of this field specifies a partial URL that is not to be visited. This can be a full path, or a partial path; any URL that
starts with this value will not be retrieved
ROBOTS.TXT EXAMPLES
The following example "/robots.txt" file specifies that no robots should visit any URL starting with "/cyberworld/map/" or "/tmp/":
User-agent: *
Disallow: /cyberworld/map/ # This is an infinite virtual URL space
Disallow: /tmp/ # these will soon disappear
This example "/robots.txt" file specifies that no robots should visit any URL starting with "/cyberworld/map/", except the robot called
"cybermapper":
User-agent: *
Disallow: /cyberworld/map/ # This is an infinite virtual URL space
# Cybermapper knows where to go.
User-agent: cybermapper
Disallow:
This example indicates that no robots should visit this site further:
# go away
User-agent: *
Disallow: /
