in reply to Replacing a specfied instance of a pattern in a string

One way:

my $foo = 'Fsih my test variable is fsihd or is it gfsih or gfsihd fsi +h'; # Replace the 3rd $foo =~ s/((?:fsih.*?){2})fsih/$1fish/i or warn "Not found"; print "Foo = $foo\n";

    or to pass the index in use:

    use warnings; use strict; my $foo = 'Fsih my test variable is fsihd or is it gfsih or gfsihd fsi +h'; my $i = 2; # Replace the 3rd $foo =~ s/((?:fsih.*?){$i})fsih/$1fish/i or warn "Not found"; print "Foo = $foo\n";

    Perl is Huffman encoded by design.
