Hi, i give you the code i have so far. I am just very new at PERL but yet i got this difficult problem(for me) to solve. 
#!/usr/bin/perl -w

$file=$ARGV[0];

@params=<STDIN>;
%numberoftimes={};
$nuoftimes=0;

while(<FH>){
     @lines=split("\n",$file);
     for $line(@lines){
        for $p(@params){
            if (index($line,$p)){
                nuoftimes++;
                #create a new file 
            }
            $%numberoftimes{$p}=$nuoftimes;
            #every time $p is found in $line,
            #i have to write that $line in the new file
            elsif($p eq "end")
            #the input of the parameters should end
        }
    }
}
