Probably the fastest way, if you are on a Unix system, is to use the **tac**
command, which can read a file line by line in reverse order, or paragraph by
paragraph, or character by character, or word by word, or by a custom separator
string or regular expression. Example for using it from Perl:

    open my $fh, "tac /etc/passwd |";
    print while <$fh>;

Another convenient way is to use the Perl I/O layer <pm:PerlIO::reverse>. It
only does line-by-line reversing, but you can use the regular Perl API. You
don't even have to `use` the module explicitly (but of course you have to get it

=head1 VERSION

This document describes version 0.003 of Acme::CPANModules::ReadingFilesBackward (from Perl distribution Acme-CPANModules-ReadingFilesBackward), released on 2023-10-31.

=head1 DESCRIPTION

Probably the fastest way, if you are on a Unix system, is to use the B<tac>
command, which can read a file line by line in reverse order, or paragraph by
paragraph, or character by character, or word by word, or by a custom separator
string or regular expression. Example for using it from Perl:

 open my $fh, "tac /etc/passwd |";
 print while <$fh>;

Another convenient way is to use the Perl I/O layer L<PerlIO::reverse>. It

=head1 CONTRIBUTING


To contribute, you can send patches by email/via RT, or send pull requests on
GitHub.

Most of the time, you don't need to build the distribution yourself. You can
simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your
system), you can install L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>,
L<Pod::Weaver::PluginBundle::Author::PERLANCAR>, and sometimes one or two other
Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond
that are considered a bug and can be reported to me.
