Windows and UNIX have different style line endings. If you run this under Win32 but use a file with UNIX-style endings, the whole file will be slurped instead of processed line by line. Try this before opening your file:

use Getopt::Long;
my $line_ending = "\012"; #unix style default
GetOptions( 'windows' => sub { $line_ending = "\015\012" } );
local $/ = $line_ending;

This will cause your script to assume UNIX line endings, but if you pass the parameter --windows to the command line, it will then assume the file has Windows-style line endings.

You could autodetect this, too, but it involves opening the file and reading until you find one of those pairs, then resetting the filehandle. I know I've seen code for that on PerlMonks...

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.


Do you know where your variables are?
