if ($string1 eq $string2){
print"\$string1 is equal to \$string2\n";

elsif ($string1 lt $string2){

== tests equality for numbers.
eq does the same for strings.
lt is the string testing equivalent of the numerical <
gt is the string testing equivalent of the numerical >
You can also use the cmp operator, which is the non-numerical
equivalent of the <=> operator:
$result = $string1 cmp $string2;
$result will be:
- 0 if the strings are equal
- 1 if string1 is greater than string2
- -1 if string1 is less than string2
