It's a little redundant to see if the string begins with a ~ and then remove it, when s/^~// will only return true if it replaced anything.
Also, it might be nice to fallback to the home directory returned by getpwuid just in case $ENV{'HOME'} isn't set ...
use File::Spec;
my $filename = '~/public_html/';
if ( $filename =~ s<^~([^/]*)/></> ) {
my $homedir = $1 ? (getpwnam($1))[7] # specified user
: $ENV{'HOME'} || (getpwuid($<))[7] # ourselves
or die "Where's your home?\n";
$filename = File::Spec->catfile($homedir, $filename);
}
Update: Fixed to account for jeffenstein's observation.
