Linux中如何查询运行文件的全路径的方法
<p>在linux中，有些地方需要使用绝对路径，对于一些命令，如java、mysql等，需要使用到运行文件所在的路径，给大家介绍一个命令，来查询这个路径。</p>
<p>
<strong>which</strong></p>
<p>
可以通过which查询运行文件的所在路径，具体如下：</p>

命令详解</p>
<p>
以mysql为例，命令如下：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_907000">
<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>
<div class="line number2 index1 alt1">
2</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">$ </code><code class="bash functions">which</code> <code class="bash plain">mysql</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">/opt/soft/percona-mysql55/bin/mysql</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
命令输出了运行文件mysql所在的路径</p>
<p>
当没有该文件时，输出如下：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_419596">

</div>
</div>
<p>
当文件不存在时，会输出 文件：空字符串</p>

<code class="bash plain">baidu:</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
<strong>find</strong></p>
<p>
也可以使用find搜索命令来查找</p>
<p>
find命令就不详细说了，举个栗子：</p>
<div class="jb51code">
