copied!<p>This works for me on a Mac (Mac OS X 10.7.5, Perl 5.16.2):</p> <pre><code>#!/usr/bin/env perl use strict; use warnings; while (<>) { print "1: [$_]\n"; { local $/ = "\r\n"; chomp; } print "2: [$_]\n"; } </code></pre> <p>Sample output:</p> <pre><code>$ odx x3.txt 0x0000: 6F 6E 69 6F 6E 0D 0A 73 74 61 74 65 0D 0A 6D 69 onion..state..mi 0x0010: 73 68 6D 61 73 68 0D 0A shmash.. 0x0018: $ perl x3.pl < x3.txt | vis -c 1: [onion^M ] 2: [onion] 1: [state^M ] 2: [state] 1: [mishmash^M ] 2: [mishmash] $ </code></pre> <p>The <code>odx</code> program gives me a hex dump of the data file; you can see that there are 0D 0A (CRLF) line endings. The <code>vis -c</code> program shows control characters (other than newline and tab) as <code>^M</code> (for example). You can see that the raw input includes the <code>^M</code> (lines starting <code>1:</code>) but the <code>chomp</code>'d lines are missing both the newline and the carriage return.</p> <p>The only issue will be whether the input on Windows is a text file or a binary file. If it is a text file, the I/O system should do the CRLF mapping automatically. If it is a binary file, it won't. (Unix doesn't have a meaningful distinction between text and binary files.) On Windows, you may need to investigate <a href="http://perldoc.perl.org/functions/binmode.html" rel="nofollow"><code>binmode</code></a>, as discussed on the <a href="http://perldoc.perl.org/functions/open.html" rel="nofollow"><code>open</code></a> page.</p>
