hi , i want to write a cgi code to open a file and access its contents character by character ( what fgetc does in C) , and then simultaneously search for a pattern (say /blue/ ) and output the results into another file.

How to access the file content chracter by character , i have tried using to do with the "do" function and $/ , but the problem is that in this manner a pattern is looked for only once .

here is the url http://83.138.185.127/cgi-bin/search3.cgi iam pasting the code below .
regards , jagan

---------------------------------------------------------- 

#!/usr/bin/perl -T

use CGI qw(:standard);
use CGI qw(warningsToBrowser fatalsToBrowser);

my $file1 = param("fil1");
my $key1  = param("phr1");
my $st1   = param("str1");

print header, start_html(-title=>"Searching for a pattern in a file" ,
+ -bgcolor=>"#cccccc");
h1("Searching for a pattern in a file" );

if(param())
{
my $file1 = param("fil1");
my $key1  = param("phr1");
my $st1   = param("str1");
my $i =0 ;

open(FILE , "$file1") or die("could not open the file $!\n");

while(<FILE>)
{
my $st1 = do{local $/ , <FILE>};
if($st1=~ m/$key1/)
{
$i++;
print p("The pattern <b> $key1</b> has been found <b> $i</b> times.\n"
+);
}
else
{
print p("The pattern <b> $key1</b> has not been found.\n");
}
print p "<a href=http://83.138.185.127/cgi-bin/search3.cgi> Try Again 
+</a> " ;
}
}

else
{
print hr() , start_form();
print p("Enter the file name you wish to make a search into" , popup_m
+enu("fil1" , ['file1' , 'file2' ,'file3' ,'file4']));
print p("Enter the key word you wish to search for " , textfield("phr1
+" , ""));
print p(submit("go") , reset("clear"));
print end_form() , hr();
}

end_html();
