*>The regular expression
*>s/^\s//;
s/^\s+//g; would be even better as it would remove all whitspace at the

my @arr = (" This has a leading space", "This does not" );
foreach my $string (@arr ) {
$string =~ s/^\s//;
print $string, "\n";
}
prints:
This has a leading space
This does not
The regular expression
s/^\s//;
means
s/ # substitute
^ # at the beginning of the string
\s
