There's an entry in the Perl FAQ for preserving case, but there's a much
simpler way:
sub case {
my ($s, $d) = @_;
$s = substr($s, 0, length($d)) if length($d) < length($s);
$d ^ (~$s & (" " x length $s));
}
Try it out:
for (qw( satellite Satellite SATELLITE )) {
print case($_ => "target"), "\n";
}
The output is
target
Target
TARGET
Its usage in a s/// is:
s/(word to change)/case($1, "word to become")/eg;
