命令是我们给计算机的指令，它可以做我们想做的任何事情。在Mac OS和Linux中，它称为终端，而在Windows中，它称为命令提示符。命令始终区分大小写。
通过在命令行中键入然后按Enter键来执行命令。
该命令进一步传递给外壳，外壳读取该命令并执行该命令。 Shell是用户与系统交互的一种方法。 Linux中的默认Shell称为bash(Bourne-Again Shell)。
Shell命令有两种类型：
| Directory Command | Description |
|---|---|
| pwd | The pwd command stands for (print working directory). It displays the current working location or directory of the user. It displays the whole working path starting with /. It is a built-in command. |
| ls | The ls command is used to show the list of a folder. It will list out all the files in the directed folder. |
