How can I test for empty strings and nulls on a particular value. When I get an empty string or a null value I need to do something.
Thanks in Advance.

# from a unix shell,
# empty string
perl -e '$s = "";unless ($s) {print "Empty string\n";}'
# null value
perl -e '$n = hex 0; unless ($n) {print "Null\n";}'
