Well, in this example you are putting new lines in the print statements (the
\n's) and it should have printed
Pacific
ocean
However, ignoring those small points, if you want to trim off white space
you can use the following :
# Trim off white space from the front of the line
$var =~ s/^\s*//;
# Trim off white space from the end of the line
$var =~ s/\s*$//;
