Hi monks,

For Large text file processing purpose,
I have two types of statement options with differnt pattern modifiers for find and replace.

$string =~ s/find /replace/g;
$string =~ s/find /replace/gs;
[download]

please suggest me a better statement among those for code optimization.
Which is the efficient statement that is less time consuming? and also please explain me
the difference between those two statements?

open (FIN, "$inputfile") || die("Cannot read the input file");
local $/;
$string = <FIN>; 
close FIN;

$string =~ s/find /replace/g;

#and

$string =~ s/find /replace/gs;

Welcomes your ideas
