The <command>cd</command> command changes directories. When you open a terminal you will be in your home directory. To move around the file system you will use <command>cd</command>.

|
<command>cd</command>命令改变目录。 打开终端后您位于主目录。要在系统中移动，需要使用 <command>cd</command>命令。

The <command>~</command> character represents the current user's home directory. As seen above, <command>cd ~</command> is equivalent to <command>cd /home/username/</command>. However, when running a command as root (using <command>sudo</command>, for example), <command>~</command> points instead to <filename class="directory">/root</filename>. When running a command with <command>sudo</command>, the full path to your home directory must be given.

<command>~</command>代表当前用户的主目录。正如上面介绍的， <command>cd ~</command> 等价于 <command>cd /home/username/</command>。 然而，当作为 root 用户时(例如使用 <command>sudo</command>命令)， <command>~</command> 指向 <filename class="directory">/root</filename>。当使用 <command>sudo</command>命令时，需要提供主目录的完整路径。

To navigate through multiple levels of directories at once, specify the full directory path that you want to go to. For example, type: <screen>cd /var/www</screen> to go directly to the <filename class="directory">/www</filename> subdirectory of <filename class="directory">/var/</filename>. As another example, type: <screen>cd ~/Desktop</screen> to move you to the <filename class="directory">Desktop</filename> subdirectory inside your home directory.

如需跨过多级目录变更当前目录，需要指明您想进入的目录的完整路径。例子一，若直接进入目录 <filename class="directory">/var/</filename> 下的子目录 <filename class="directory">/www</filename>，则键入：<screen>cd /var/www</screen>。例子二，若进入 home 目录下的子目录 <filename class="directory">Desktop</filename>，则键入：<screen>cd ~/Desktop</screen>。

The <command>pwd</command> command outputs which directory you are currently located in (<acronym>pwd</acronym> stands for <quote>print working directory</quote>). For example, typing <screen>pwd</screen> in the <filename class="directory">Desktop</filename> directory, will show <computeroutput>/home/username/Desktop</computeroutput>. <placeholder-1/>
