osx - Parse Output of Command into Variable LIVE (Network Traffic Monitoring) -

i writing network monitoring script in bash. base command using ettercap -t -m arp -i en1 // //. pipe egrep --color 'host:|get' it.

a sample output getting looks this:

get /images/srpr/logo11w.png http/1.1. host: www.google.com. /en-us/us/products http/1.1. host: www.caselogic.com. 

my desired output this:

title: logo11w.png url: www.google.com/images/srpr/logo11w.png http/1.1.  title: products - case logic url: www.caselogic.com/en-us/us/products 

things notice: http/1.1. , . @ end of host gone. formed 1 url , there blank line after each title/url listing. attempted forming them 1 url parsing commands output variable with

var=`sudo ettercap -t -m arp -i en1 // // | egrep --color 'host:|get'` | echo $var 

but doesn't work because input variable command isn't done until user requests stop (ctrl + c).

to title of html page, use command wget -qo- 'https://url.goes/here' | perl -l -0777 -ne 'print $1 if /<title.*?>\s*(.*?)\s*<\/title/si'. if doesn't have title, such image, no title fine.

any appreciated, , sorry if wrote hard read, feel free ask questions.

try this:

title_host.pl

#!/usr/bin/env perl  use warnings; use strict; use www::mechanize;  $mech = www::mechanize->new();  ($get,$host,$title); while (<>) {     if (m|^get (\s+) |) {         $get = $1;     } elsif ( m|^host: (\s+)\.| ) {         $host = $1;     } else {         # unrecognized line...reset         $get = $host = $title = '';     }      if ($get , $host) {         ($title) = $get =~ m|^.*\/(.+?)$|; # default title         $url = 'http://' . $host . $get;         $mech->get($url);         if ($mech->success) {             # html may have title, images not             $title = $mech->title() || $title;         }         print "title: $title\n";         print "url: $url\n";         print "\n";          $get = $host = $title = '';     } } 

input

get /images/srpr/logo11w.png http/1.1. host: www.google.com. /en-us/us/products http/1.1. host: www.caselogic.com. 

now pipe input perl script:

cat input | perl title_host.pl 

output:

title: logo11w.png url: http://www.google.com/images/srpr/logo11w.png  title: products - case logic url: https://www.caselogic.com/en-us/us/products
