This is an excerpt from the latest version perlfaq5.pod, which
comes with the standard Perl distribution. These postings aim to
reduce the number of repeated questions as well as allow the community
to review and update the answers. The latest version of the complete
perlfaq is at http://faq.perl.org .

--------------------------------------------------------------------

5.30: How can I read in a file by paragraphs?

Use the $/ variable (see perlvar for details). You can either set it to
"" to eliminate empty paragraphs ("abc\n\n\n\ndef", for instance, gets
treated as two paragraphs and not three), or "\n\n" to accept empty
paragraphs.

Note that a blank line must have no blanks in it. Thus
"fred\n \nstuff\n\n" is one paragraph, but "fred\n\nstuff\n\n" is two.

The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.

If you'd like to help maintain the perlfaq, see the details in
perlfaq.pod.
