用大写字母输入Linux命令以将其作为sudo用户运行

我非常喜欢 Linux 社区的原因是他们创建了很多有趣的项目，你很少能在任何其他操作系统中找到它们。不久前，我们看了一个名为 Hollywood 的有趣项目，它在类 Ubuntu 系统将终端变成了好莱坞技术情景剧的黑客界面。还有一些其他工具，例如 cowsay、fortune、sl 和 toilet 等，用来消磨时间自娱自乐！它们可能没有用，但这些程序娱乐性不错并且使用起来很有趣。今天，我偶然发现了另一个名为 SUDO 的类似工具。正如名字暗示的那样，你无论何时用大写字母输入 Linux 命令，SUDO 程序都会将它们作为 sudo 用户运行！这意味着，你无需在要运行的 Linux 命令前面输入 SUDO。很酷，不是么？

安装 SUDO

提醒一句：

在安装这个程序（或任何程序）之前，请查看源代码（最后给出的链接），并查看是否包含会损害你的系统的可疑/恶意代码。在 VM 中测试它。如果你喜欢或觉得它很有用，你可以在个人/生产系统中使用它。

用 Git 克隆 SUDO 仓库：

1. <span class="pln">$ </span><span class="kwd">git</span><span class="pln"> </span><span class="kwd">clone</span><span class="pln"> https</span><span class="pun">:</span><span class="com">//github.com/jthistle/SUDO.git</span>

此命令将克隆 SUDO GIT 仓库的内容，并将它们保存在当前目录下的 SUDO 的目录中。

1. <span class="typ">Cloning</span><span class="pln"> into </span><span class="str">'SUDO'</span><span class="pun">...</span>
2. <span class="pln">remote</span><span class="pun">:</span><span class="pln"> </span><span class="typ">Enumerating</span><span class="pln"> objects</span><span class="pun">:</span><span class="pln"> </span><span class="lit">42</span><span class="pun">,</span><span class="pln"> </span><span class="kwd">done</span><span class="pun">.</span>

切换到 SUDO 目录：

1. <span class="pln">$ </span><span class="kwd">cd</span><span class="pln"> SUDO</span><span class="pun">/</span>

并使用命令安装它：

1. <span class="pln">$ </span><span class="pun">./</span><span class="pln">install</span><span class="pun">.</span><span class="pln">sh</span>

该命令将在 ~/.bashrc 文件中添加以下行：

1. <span class="pun">[...]</span>
2. <span class="com">#</span><span class="pln"> SUDO </span><span class="pun">-</span><span class="pln"> shout at </span><span class="kwd">bash</span><span class="pln"> to </span><span class="kwd">su</span><span class="pln"> commands</span>

22. <span class="com">#</span><span class="pln"> </span><span class="kwd">end</span><span class="pln"> SUDO</span>

它还会备份你的 ~/.bashrc 并将其保存为 ~/.bashrc.old。如果有重大错误，你可以恢复它。

最后，使用命令更新更改：

1. <span class="pln">$ source </span><span class="pun">~/.</span><span class="pln">bashrc</span>

现在，用大写字母中输入 Linux 命令，将它们作为 Sudo 用户运行

通常我们像下面那样执行需要 sudo/root 权限的命令。

1. <span class="pln">$ </span><span class="kwd">sudo</span><span class="pln"> </span><span class="kwd">mkdir</span><span class="pln"> </span><span class="pun">/</span><span class="pln">ostechnix</span>

对么？没错！上面的命令将在根目录（/）中创建名为 ostechnix 的目录。让我们使用 Ctrl + c 取消。

一旦安装了 SUDO，你就可以在不使用 sudo 的情况下输入任何大写 Linux 命令并运行它们。因此，你可以像下面那样运行上面的命令：

1. <span class="pln">$ MKDIR </span><span class="pun">/</span><span class="pln">ostechnix</span>
2. <span class="pln">$ TOUCH </span><span class="pun">/</span><span class="pln">ostechnix</span><span class="pun">/</span><span class="kwd">test</span><span class="pun">.</span><span class="pln">txt</span>
3. <span class="pln">$ LS </span><span class="pun">/</span><span class="pln">ostechnix</span>
