hello, I have this script but it fails to run. It was orginaly set to run on a unix box( See below), so I changed the path to my my windows path wihere my input file is located.

When I run it, it fails to look at my directory where the files are located.

My input file is located at c:\named.conf-rich

Can someone fix this so it will run on my windows box.

Thanks

#!/perl
 
unless ($ARGV[0])  {
    print "******************************************************\n";
    print "*                                                    *\n";
    print "*                                                    *\n";
    print "******************************************************\n";
    exit;
}
 
$inputfile=$ARGV[0];
$zonefound = 0;
 
open(INFILE, $inputfile) or die "Unable to find $inputfile\n";
@conf = <INFILE>;
close INFILE;
 
foreach $linein (@conf)  {
    chomp($linein);
    $count++;
 
        if ($linein =~ /^zone\s+\".*in-addr.arpa\"/)  {
            $countZONE++;
            $zonefound = 1;
            ($j1, $j2, $j3, $j4, $j5) = split " ",$linein;
#print "ZONE-START: $linein\n";
        }
        elsif (($zonefound == 1) and ($linein =~ /^\}/))  {
            $zonefound = 0;
#print "  ZONE-END: $linein\n";
        }
        elsif (($zonefound == 1) and ($linein =~ /allow-update/))  {
print "$j2,$linein\n";
        }
        else {
                next;
        };
 
};

Hi,
Well, first I am unsure of the $input file in terms of what I need to set. I do know that my input file is located in c:\named.conf\-rich

In that directory I have tons of file called
named.conf.6cmghnsrt01.netdevice.rich.com

What this script will do is look at the contents of what is directed.

So, I want to make sure when I run this script, I need it to look at the directory c:\named.conf\-rich and look at all the files that begin with named.conf and pull out what the script does.

I think the script runs with script name and filename, checkconf.pl

named.conf.6cmghnsrt01.netdevice.rich.com
 
I do not want it to do that. I want it to look in my dir and do it automaticlay.
Thanks

do you want to read @ARGV=<c:/named.conf/-rich/*>?
how would you have done what you are trying to do in unix?
the code snippet does not seem to match your description.

Hi, yes, My script for unix is what I want to make work for my needs. The script I have is a baseline which I think is close to what I need.
So, yes my input file is c:\named.conf-rich which will contain all the files I need for this script to read.
Thanks Ozo

The script you posted expects you to give it the name of a file as a command line argument, like so:
    script.pl c:\named.conf-rich\list.txt

The script then reads that file, and counts the number of zones (lines beginning with "zone") in them.

Hi Adam, I know , I want it to read a specific directory and work from there. That is why I needed this script to be slightly re-worked.
I rather have this script work in a wau where I excute the script, it will look in my directory, in this case c:\named.conf-rich
In there it will find all the files that start with named.conf.xxxxx and spit out what its designed to do from there.
Does that sound do'able

Hi Ozo, so this will go like this in my scirpt
#!/perl
 
unless ($ARGV[0])  {
    print "******************************************************\n";
    print "*                                                    *\n";
    print "*                                                    *\n";
    print "******************************************************\n";
    exit;
}
 
#open(c:\named.conf-rich, $inputfile) or die "Unable to find $inputfile\n";
#@conf = <INFILE>;
#close INFILE;
 
#foreach $linein (@conf)  {
 
@ARGV=<$c:/named.conf-rich/named.conf.*>;
while( $linein=<> ){ 
foreach $linein (@conf)  {
    chomp($linein);
    $count++;
 
        if ($linein =~ /^zone\s+\".*in-addr.arpa\"/)  {
            $countZONE++;
            $zonefound = 1;
            ($j1, $j2, $j3, $j4, $j5) = split " ",$linein;
#print "ZONE-START: $linein\n";
        }
        elsif (($zonefound == 1) and ($linein =~ /^\}/))  {
            $zonefound = 0;

no,
#foreach $linein (@conf)  {
should be  commented out
and $c would need to be defined.
If you are not reading $c = $ARGV[0];
instead of $inputfile=$ARGV[0];
then you could code the path you want into the <>

Awsome, so where it says
#@conf = <INFILE>;
I need to put:
@conf = <c:\named.conf-rich>;

In the new code, @conf isn't used.  This line:
    @ARGV=<c:/named.conf-rich/named.conf.*>;
is the line that searches for the files named c:\named.conf-rich\named.conf.*.

Then this line:
    while( $linein=<> ){
is what reads from those files, one line at a time.

No, that's not what I wrote.
But now I'm getting confused
But is c:\named.conf-rich a text file or a directory

ok, so we can assume this puppy will work as below
#!/perl
 
#unless ($ARGV[0])  {
#    print "******************************************************\n";
#    print "*                                                    *\n";

#    print "******************************************************\n";
#    exit;
#}
 
#$inputfile=$ARGV[0];
$zonefound = 0;
 
#open(INFILE, $inputfile) or die "Unable to find $inputfile\n";
#@conf = <INFILE>;
#close INFILE;
 
#foreach $linein (@conf)  {
 
@ARGV=<c:/named.conf-rich/named.conf.*>;  #i ignore $inputfile=$ARGV[0];
 and always look for c:/named.conf-rich/named.conf.*
while( $linein=<> ){
 
    chomp($linein);
    $count++;
 
        if ($linein =~ /^zone\s+\".*in-addr.arpa\"/)  {
            $countZONE++;
            $zonefound = 1;
            ($j1, $j2, $j3, $j4, $j5) = split " ",$linein;
#print "ZONE-START: $linein\n";
        }
        elsif (($zonefound == 1) and ($linein =~ /^\}/))  {
            $zonefound = 0;
#print "  ZONE-END: $linein\n";
        }
        elsif (($zonefound == 1) and ($linein =~ /allow-update/))  {
print "$j2,$linein\n";
        }

Cleaning up your code...
#!/perl
 
$zonefound = 0;
@ARGV=<c:/named.conf-rich/named.conf.*>;
 
while( $linein=<> ){
    chomp($linein);
    $count++;
    if ($linein =~ /^zone\s+\".*in-addr.arpa\"/)  {
        $countZONE++;
        $zonefound = 1;
        ($j1, $j2, $j3, $j4, $j5) = split " ",$linein;
    }
    elsif (($zonefound == 1) and ($linein =~ /^\}/))  {
        $zonefound = 0;
    }
    elsif (($zonefound == 1) and ($linein =~ /allow-update/))  {
        print "$j2,$linein\n";
    }
    else {
        next;
    }

I guess the basic problem you were facing initially is like this:
When you were using arguments for giving the path, then you were entering the path with front slashes '\'
Whereas for perl script you should have done it with '/'

So the argument should have been 'c:/named.conf-rich' instead of 'c:\named.conf-rich'.
Rest of the logic changes for reading all files in the directory is well suggested by experts above.
I just added this, in case you again want to take user input for path, instead of hard coding.
