I'm a big fan of debugging by print statements. When I'm using print statements to see what's in a variable, I'll wrap the variable in some odd characters to see special characters that otherwise might not show up on the screen.
If you change this line:
print "name is $name\n";
to something like this:
print "name is |||$name|||\n";
you'll see tabs, spaces, newlines, etc. at the beginning and end of your variable you might not otherwise notice.
