|
||
<p> <code class="filename">shells</code> 文件是当前系统所有可用 shell
|
||
的列表文件。应用程序通过读取它可以知道需要使用的 shell 是否有效。每行指定一个可用的 shell，且需要为绝对路径。</p>
|
||
<p> 例如，当非特权用户想要使用<strong> </strong><span class="command"><strong>chsh</strong></span>
|
||
命令更改自己登录所用的 shell 时。如果命令没有在 /etc/shell 中找到，那么将会拒绝更改。</p>
|
||
<p> It is a requirement for applications such as <span
|
||
class="application">GDM</span> which does not populate the
|
||
face browser if it can't find <code class="filename">/etc/shells</code>,
|
||
or FTP daemons which traditionally disallow access to users with
|
||
shells not included in this file. </p>
|
||
<pre class="root"><kbd class="command">cat > /etc/shells << "EOF"
|
||
<code class="literal"># Begin /etc/shells
|
||
|
||
/bin/sh
|
||
/bin/bash
|
||
|
||
# End /etc/shells</code>
|
||
EOF</kbd>
