The only problem I had with your code is the 'S' symbol.
Under the 'strict' pragma the program requires 's' for the substitution expression.
Now I can't match
oko1 in code size (nor anywhere else), but inspired from the
funny discovery that your arguments are in alphabetic order, here is my code
use strict;
my @params=qw(input output pattern replacement);
my %settings; @settings{@params}=("0")x @params;
foreach my $key (sort keys %settings) {
print "$key=";
chomp($settings{$key}=<>);
}
open IN,"<",$settings{"input"} || die "not a rockstar today";
-e $settings{"output"} and die("File Exists..will not override!") or o
+pen(OUT,">",$settings{"output"}) or die "Error while opening file: $!
+";
while (<IN>) { #
s/$settings{"pattern"}/$settings{"replacement"}/g;
print OUT $_;
} # end while
close (IN);
close (OUT);
