The backslash (\) at the end of the line continues the command to the next line. Don't end the last line of the command with a backslash and it will execute the whole command.
行尾的反斜杠 (\) 将命令延续到下一行。不要以反斜杠结束命令的最后一行，它将执行整个命令。
If you have an unclosed quote (" or '), the command also won't complete until you close the quote. Also some uncompleted commands are detected and continue to prompt you for the rest of the command. In bash, simply typing 'if' for example won't complete until the shell sees the terminating 'fi'.
如果您有未关闭的引号（" 或 '），则在关闭引号之前，该命令也不会完成。还会检测到一些未完成的命令并继续提示您输入命令的其余部分。在 bash 中，只需键入 'if ' 例如，在 shell 看到终止的 'fi' 之前不会完成。

The first line not ending with a '\' will execute it.
不以“\”结尾的第一行将执行它。
