In order to compare for string equality, or if one string is alphabetically bigger than another, you can use the six string comparison operators. Here are the string operators together with the numerical operators they correspond too:
| String Operator | Numerical Operator |
| eq | == |
| ne | != |
| gt | > |
| lt | < |
| ge | >= |
| le | <= |
Notice that the string operators are built from the initials of their abbreviated names. (E.g: eq = equal, gt = greater than). Perl’s string comparison is case-sensitive. If you want a case insensitive string comparison, use the lc function to convert the strings to lowercase beforehand.
I’m extremely impressed with your writing skills as well as with the layout on your weblog. Is this a paid theme or did you modify it yourself? Anyway keep up the excellent quality writing, it is rare to see a nice blog like this one today..
