Wrench Need help in writing perl script

Hi,

I am new to perl.

I am trying to write a small perl script for search and replace in a file :

========================================================
Code:
#!/usr/bin/perl

 
my $searchStr = "register_inst\.write_t\(";
my $replaceStr = "model\.fc_block\.";

open(FILE,"temp.sv") || die("Cannot Open File");
my(@fcont) = <FILE>;
close FILE;

open(FOUT,">temp.sv") || die("Cannot Open File");
foreach $line (@fcont) {

    $line =~ s/$searchStr/$replaceStr/g;


    print FOUT $line;
}
close FOUT;

==========================================================

what is wrong with this code? its not working, can somebody help me in writing correct working code.

Thx in advance.

Rgds,
ravi.

Replace the double quotes with single quotes in the search- and replaceStr:

Code:
my $searchStr = 'register_inst.write_t\(';
my $replaceStr = 'model.fc_block.';
