Perl:how to find multiple strings
Hi , i'm trying to find lines in a file that have 2 matches,but i have trouble with regex -it doesn't search for a second string-please help
Code:
#!/usr/bin/perl -w
use strict;
use warnings;

my $log = "log";
my $log_string = "grep '^8=' $log |";
usage ();
chomp (my $TAB_1 = $ARGV[0]);
chomp (my $TAB_5 = $ARGV[1]); 
open (my $HAN, "$log_string") || die "Problems grepin... : $!";
my @contents = <$HAN>;
my $matches = grep /1=$TAB_1 && 5=$TAB_5/, @contents ;
 foreach (@matches) 
   { 
      print "[+] FOUND $TAB_1 and $TAB_5 in\n",
"-----------------------\n",
"$_" ;}

now you can do it like
Code:
foreach (@contents)
if /1=$TAB_1 && 5=$TAB_5 /

that also doesn't find lines with those 2 matches

weather::com::finder

Weather::Com::Finder(3pm)				User Contributed Perl Documentation				 Weather::Com::Finder(3pm)

NAME

       Weather::Com::Finder - finder class to search for weather.com location's

SYNOPSIS

	 #!/usr/bin/perl -w
	 use Weather::Com::Finder;

	 # you have to fill in your ids from weather.com here
	 my $PartnerId	= 'somepartnerid';
	 my $LicenseKey = 'mylicense';

	 my %weatherargs = (
	       'partner_id' => $PartnerId,
	       'license'    => $LicenseKey,
	 );

	 my $finder = Weather::Com::Finder->new(%weatherargs);

	 # if you want an array of locations:
	 my @locations = $finder->find('Heidelberg');

	 # or if you prefer an arrayref:
	 my $locations = $finder->find('Heidelberg');

	 foreach my $location (@locations) {
	   print "Found weather for city: ", $location->name(), "
";
	   print "Current Conditions are ",
	     $location->current_conditions()->description(), "
";
	 }

DESCRIPTION

       The usual way to use the Weather::Com module would be to instantiate a Weather::Com::Finder that allows you to search for a location by
       providing a search string or postal code or any other search string that weather.com understands.

       The finder returns an arrayref or an array of locations (depending on how you call the "find()" method). Each location is an object of
       Weather::Com::Location.

CONSTRUCTOR

       new(hash or hashref)

       The constructor takes a configuration hash or hashref as described in the Weather::Com POD. Please refer to that documentation for further
       details.

METHODS

       find(search string)

       Once you've instantiated a finder object, you can perform "find()" calls to search for locations in the weather.com database.

       The "find()" method returns an array of Weather::Com::Location objects if you call it in list context, else an arrayref.

       Returns undef if no matching location could be found.

SEE ALSO

       See also documentation of Weather::Com and Weather::Com::Location.
