shell脚本

In the command line, a shell script is an executable file that contains a set of instructions that the shell will execute. Its main purpose is to reduce a set of instructions (or commands) in just one file. Also it can handle some logic because it’s a programming language.

在命令行中，shell脚本是一个可执行文件，其中包含该Shell将执行的一组指令。 它的主要目的是减少一个文件中的一组指令(或命令)。 由于它是一种编程语言，因此它还可以处理一些逻辑。

如何建立 (How to create it)

Create the file:

创建文件：

$ touch myscript.sh

Add a shebang at the start of the file. The Shebang line is responsible for letting the command interpreter know which interpreter the shell script will be run with:

在文件的开头添加一个Shebang 。 Shebang行负责让命令解释器知道将运行shell脚本的解释器：

$ echo "#!/bin/bash" > myscript.sh
# or
$ your-desired-editor myscript.sh
# write at the first line #!/bin/bash

Add some commands:

添加一些命令：

$ echo "echo Hello World!" >> myscript.sh

Give the file execution mode:

给出文件执行方式：

$ chmod +x myscript.sh

Execute it!

执行它！

$ ./myscript.sh
Hello World!
