#!/usr/bin/perl print "Hello, World!\n"; The hash mark character introduces a comment in Perl, which runs up to the end of the line of code and is ignored by the compiler (except on Windows). The comment used here is of a special kind: it’s called the shebang line.
will fix the problem. This is actually a pretty common mistake, and perl will catch it for you if you turn "warnings" on. To do that, change the first line to: #!/usr/bin/perl -w and perl will say: Useless use of sort in void context at line 10. which is a little obscure, but at least tells you to look for trouble on that line.
#!/usr/bin/perl # Loads the module and imports any functions into our namespace # (defaults to "main") exported by the module. Hello::World exports # hello() by default. Exports can usually be controlled by the caller. use Hello::World; print hello (); # prints "Hello, world!\n" print hello ("Milky Way"); # prints "Hello, Milky Way!\n"
Perl is a highly expressive programming language: source code for a given algorithm can be short and highly compressible. [17] [18] Perl gained widespread popularity in the mid-1990s as a CGI scripting language, in part due to its powerful regular expression and string parsing abilities.
#!usr/bin/perl – called the "shebang line", after the hash symbol (#) and ! (bang) at the beginning of the line. It is also known as the interpreter directive. # – the number sign, also called the hash symbol. In Perl, the # indicates the start of a comment. It instructs perl to ignore the rest of the line and not execute it as script code.
More broadly using #!/usr/bin/env for any script still has some portability issues with OpenServer 5.0.6 and Unicos 9.0.2 which have only /bin/env and no /usr/bin/env. Using #!/usr/bin/env results in run-time indirection, which has the potential to degrade system security; for this reason some commentators recommend against its use [ 17 ] in ...
