For example, it's common to set an alias (' ll '), which expands to 'ls -l', for a long listing of a directory or list of files.

例如，设置别名(' ll ')是很普遍的，该别名展开为' ls - l '，用于获得目录或文件列表的长清单。

For example, when you use ls, which reads the contents of the specified directory, it sends the list of files to the standard input of the program that called it (the shell).

例如，当用ls时，它会读取指定目录的内容，并将文件列表发送给调用它的程序(shell)的标准输入。
