Perl Scripts
Superficially a Perl script looks similar to a shell or an Awk
script, and consists of a sequence of statements. Blocks
of code can be enclosed in braces, and many of the basic commands,
such as printf, are the same. There is one initial
difference that often confuses, which is that every
statement must be terminated by a semicolon. The end of a
line has no significance to Perl.
