Problem with searching for an entry in a file

nisha has asked for the wisdom of the Perl Monks concerning the following question:

Hello Perl monks, I have an issue w.r.t to searching for an entry in a file... I haver text file of the format:

C:\EITV10CM\base\repair\Companion_Repair\File2File\F2F.COM ... is OK.
C:\EITV10CM\base\repair\Companion_Repair\File2SelfExt\F2SEXT.CMP ... i
+s OK.
C:\EITV10CM\base\repair\Companion_Repair\File2SelfExt\F2SEXT.COM ... F
+ound the CMPAN/File2SelfExt virus !!!
        The virus has been removed from the file.
Checking for another virus in the file ...              
C:\EITV10CM\base\repair\Companion_Repair\File2SelfExt\F2SEXT.COM ... i
+s OK

Below is the piece of code which was written by me...

#!/usr/bin/perl
use strict;
use warnings;
#Program to read the command line report file; and extract the virus d
+etection name for a file.
my $cmdrep = "d:/eitv10cm_cln.rep";


my $fname = "D:\\EITV10CM\\base\\repair\\Companion_Repair\\File2SelfEx
+t\\F2SEXT.COM";
my ($found,$virusname,$flag,$i);
(@dirtemp) = split /:/,$fname
shift @dirtemp;
foreach $itemp ( @dirtemp  )
{
   $filepath .= $itemp;
}
    
    open FH, "$cmdrep" or die "Cannot open $cmdrep. \n";
    while (<FH>) 
    {    
        chomp;
        next if $_ !~ /^\Q$filepath\E/i;
        chomp($_);
        /\s\.{3}\s(.*)/;
        $found = $1;
        if ($found eq "is OK.")
        {
            $virusname = "OK";
            print "The virus detection name is $virusname\n";
            last;
            
        }
        if ($found =~ /^Found: (.*?) NOT a virus[.]/) 
        {
            $virusname = $1;
            print "The virus detection name is $virusname\n";
            last;
        }
        elsif ($found =~ /^Found the (.*?) (virus|trojan) !!!/) 
        {
                $virusname = $1;
                print "The virus detection names is $virusname\n";
                last;
        }
        elsif ($found =~ /^Found potentially unwanted program (.*?)[.]
+/)
        {
            $virusname = $1;
            print "PuPs $virusname \n";
            last;
        }
        elsif ($found =~ /Found (virus or variant|application) (.*?)( 
+!!!|[.])/) 
        {
            $virusname = $2;
            print "Virus or variant $virusname \n \n";
            $flag =1;
            last;
        } 
        
    }
    close(FH);
}

Since the drive letters in the variable and text file are the only ones which vary, i have tried to remove the drive letter from $fname; this doesnt match in the text file at all even though the remaining of the string is the same. Could u please help me with this...dont know how to go about doing it.

Although you have `use strict;` at the top of your code, the line `(@dirtemp) = split /:/,$fname` can not be right. It is missing a semicolon at the end of the line and my off the front. There are other similar errors. That aside, your problem is `next if $_ !~ /^\Q$filepath\E/i;` trys to match from the start of the line (the ^ in the regex). Instead use `/\Q$filepath\E/i;` for the regex. DWIM is Perl's answer to Gödel	[reply] [d/l] [select]

Hi nisha, You have used strict and warnings but you have not declared the variables properly. Also you have splitted with ':' but you have not removed that from the file content because you are using '^' anchor, else you remove that anchor. use strict; use warnings; #Program to read the command line report file; and extract the virus d +etection name for a file. my $cmdrep = "d:/eitv10cm_cln.rep"; my $fname = "D:\\EITV10CM\\base\\repair\\Companion_Repair\\File2SelfEx +t\\F2SEXT.COM"; my ($found,$virusname,$flag,$i); my (@dirtemp) = split /:/,$fname; #declared the variables with my shift @dirtemp; my $filepath; foreach my $itemp ( @dirtemp ) { $filepath .= $itemp; } while (<DATA>) { chomp; $_ =~ s/\w\://; #you are missing this line next if $_ !~ /^\Q$filepath\E/i; #else remove the anchor chomp($_); /\s\.{3}\s(.)/; $found = $1; print "$found\n"; if ($found eq "is OK.") { $virusname = "OK"; print "The virus detection name is $virusname\n"; last; } if ($found =~ /^Found: (.?) NOT a virus[.]/) { $virusname = $1; print "The virus detection name is $virusname\n"; last; } elsif ($found =~ /^Found the (.?) (virus\|trojan) !!!/) { $virusname = $1; print "The virus detection names is $virusname\n"; last; } elsif ($found =~ /^Found potentially unwanted program (.?)[.] +/) { $virusname = $1; print "PuPs $virusname \n"; last; } elsif ($found =~ /Found (virus or variant\|application) (.*?)( +!!!\|[.])/) { $virusname = $2; print "Virus or variant $virusname \n \n"; $flag =1; last; } } __DATA__ C:\EITV10CM\base\repair\Companion_Repair\File2File\F2F.COM ... is OK.
