推荐答案

./script.sh期望该文件位于当前目录中，并已设置了执行位，并且文件的第一行是解释器开始的路径与(蛇帮线)

./script.sh expects that this file is in the current directory, has execute bit set and the first line of the file is path to the interpreter to start with ( Shebang line )

bash script.sh意味着您调用bash并将要执行(解释)的文件内容作为bash命令传递.这样，您的文件就无需可执行，并且具有一个shebang行.

bash script.sh means that you invoke bash and pass the contents of the file to be executed(interpreted) as bash commands. This way your file doesn't need to be executable and has a shebang line.

如果满足./script.sh的条件，则两次调用将导致相同的结果.

If the conditions for ./script.sh are met then both invocations lead to the same result.
