exit;



Does the line 'exit;' have to be the last line in every Perl script?

No it doesn't. At least i've never put exit at the bottom of my perl scripts and they seems to work fine. The only line that must be there that I know of is #!/usr/bin/perl and that's always the very first line of your script. I'm only a newbie to perl though so I could of gotten it wrong. Please feel free to correct me if you know otherwise.

I hope that helps.

No. In fact, it is a better standard to always end every perl script with a "1;". This is so if you choose to use or require this script from another location, it will be sure to return a true in the last statement.

As quoted from: http://perldoc.perl.org/functions/require.html


The file must return true as the last statement to indicate successful execution of any initialization code, so it's customary to end such a file with 1; unless you're sure it'll return true otherwise. But it's better just to put the 1; , in case you add more statements.

thanks for those comments, the reason i was asking was because I have seen alot of code with 'exit;' as the last line in the code........
