详解Linux文本文件与WIN文本文件换行格式转换命令
<p><strong>详解Linux文本文件与WIN文本文件换行格式转换命令</strong></p>
<p>
<strong>前言：</strong></p>
<p>
有 时在WIN下编辑好的脚本文件上传到LINUX服务器中不能正常执行，开始误认为是LINUX配置问题，后来发现，是WIN与LINUX存储文件时的换行 符标志不同造成的。在DOS使用的换行符为 ^M$，我们称为CR与LF两个符号。而在Linux中，则仅有LF ($) 这个换行符。</p>
<p>
可以用如下命令完成格式转换：$dos2unix,$unix2dos。但这两个命令在UBUNTU发行版本中不存在，可通过：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_873559">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">$</code><code class="bash functions">sudo</code> <code class="bash plain">apt-get </code><code class="bash functions">install</code> <code class="bash plain">tofrodos</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
命令安装。之后，再次使用如下文所示的格式即可。</p>

<p>
<strong>参数：</strong></p>
<p>
-k : 保留该文件原来的mtime时间格式（不更新文件上次内容经过修改的时间）</p>
<p>
-n : 保留原来的旧文件，将转换后的内容输出到新文件，如：dos2unix -n old new</p>
<p>
范例：</p>
<p>
范例一：将提供的hosts文件格式更新为dos格式。</p>

# 此时hosts文件的时间不会改变，但内容主要将换行符修改成为DOS的CRLF了。</p>
<p>
范例二：将范例一已经变成DOS格式的hosts改名为hosts.dos，并且转换Linux</p>
<p>
格式到hosts.linux</p>
