Simply put: It activates warnings for code you did not write. It is an extremely good idea to enable warnings for all code you write yourself. However if you enable it for code written by authors who did not want warnings, or for old modules, then you will get pointless messages you cannot fix. -- With regards, Christian Walde -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/

You'll get weird error messages if you leave that in.

Re: very starting help
Hello Anant, #!/usr/bin/perl is a *shebang* and is useful only in unix-like systems where it refers to the location of the interpreter. Under other systems the interpreter ignores this line as a comment. Shebang lines are useful to execute a script directly without having to specify the interpreter. Consider a script named main.pl which can be executed under unix-like systems as: perl main.pl or ./main.pl # system checks the shebang line for the interpreter to use For more information: http://en.wikipedia.org/wiki/Shebang_(Unix) Regards, Alan Haggai Alavi. -- The difference makes the difference. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
