Hi all. I'm trying to remove lines from a file based on the lines given in another file. My code actually works but stops with an error

Can't find Unicode property definition "R" at c:/remove.pl line 23, <CURRENTDAT> line 8.

Line 8 is the last line in the file test.dat (this error changes if I add lines it is always the last line). Line 23 is the pattern match part of the code. If I print the lines as it goes it is less than half way through Bad_Shares.TXT and the line changes as I add lines to test.dat (running out of memory?). This is my early test script before I get it to go through a list of files in a given directory (lots of DATs containing drives to map for specific users).

Any help appreciated. I also tried VBS got close but what a nightmare!


# Open the file containing the matches to remove
open(BADSHARES, "c:/testy/Bad_Shares.txt");
@BadShares = <BADSHARES>;

# Open the file/s to remove these matches from
open(CURRENTDAT, "c:/testy/test.dat");
@DatLines = <CURRENTDAT>;    

# For each line in the file to match from

for ($a = 0; $a < scalar(@DatLines); $a++)
{
    # Go through each line of the file to remove these matches from

    for ($i = 0; $i < scalar(@BadShares); $i++)
    {

    # If the current line in the DAT matches any line in the file to m
+atch set that line to zero


#    print "$DatLines[$a]       $BadShares[$i]";
    if ($DatLines[$a] =~ m/($BadShares[$i])/i)    

            {    
            print "MATCH  $DatLines[$a]       $BadShares[$i]";
            # $DatLines[$a]=""    
            }

    }
}
