# Shell脚本
|
|||
|
|
|
|||
|
|
在命令行中，shell脚本是包含集合的可执行文件 shell将执行的指令。它的主要目的是减少 只有一个文件中的一组指令（或命令）。它也可以处理 一些逻辑，因为它是一种编程语言。
|
|||
|
|
|
|||
|
|
## 如何创建它
|
|||
|
|
|
|||
|
|
1）创建文件：
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
$ touch myscript.sh
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
2）在文件的开头添加一个[shebang](https://en.wikipedia.org/wiki/Shebang_(Unix)) 。 Shebang行负责让命令解释器知道将运行shell脚本的解释器：
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
$ echo "#!/bin/bash" > myscript.sh
|
|||
|
|
# or
|
|||
|
|
$ your-desired-editor myscript.sh
|
|||
|
|
# write at the first line #!/bin/bash
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
3）添加一些命令：
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
$ echo "echo Hello World!" >> myscript.sh
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
4）给出文件_执行_模式：
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
$ chmod +x myscript.sh
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
5）执行它！
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
$ ./myscript.sh
|
|||
|
|
Hello World!
|
|||
|
|
```
|
|||
