编辑并用五个位置参数运行test.sh脚本,其内容如下: #!/bin/bash # ScriptName: vartest.sh # To test Positional Parameters & Special Parameters. echo "Hello,$USER,the output of this script are as follows:" echo "The script name is : $(basename $0)" echo "The first param of the script is : $1" echo "The second param of the script is : $2" echo "The tenth param of the script is : ${10}" echo "All the params you input are : $@" echo "All the params you input are : $*" echo "The number of the params you input are: $#" echo "The process ID for this script is : $$" echo "The exit status of this script is : $?”

好的,以下是编辑并用五个位置参数运行test.sh脚本的步骤:
1. 打开命令行终端,进入存放test.sh脚本的目录。
2. 执行以下命令进行编辑:
```
nano test.sh
```
3. 将脚本内容替换为以下内容:
```
#!/bin/bash
# ScriptName: vartest.sh
# To test Positional Parameters & Special Parameters.
echo "Hello,$USER,the output of this script are as follows:"
echo "The script name is : $(basename $0)"
echo "The first param of the script is : $1"
echo "The second param of the script is : $2"
echo "The tenth param of the script is : ${10}"
echo "All the params you input are : $@"
echo "All the params you input are : $*"
echo "The number of the params you input are: $#"
echo "The process ID for this script is : $$"
echo "The exit status of this script is : $?"
```
4. 按下Ctrl+X,然后按下Y键保存并退出编辑器。
5. 执行以下命令用五个位置参数运行脚本:
```
bash test.sh param1 param2 param3 param4 param5
```
其中,param1至param5分别代表五个位置参数。
6. 脚本将输出以下内容,其中$USER将显示当前用户名,$$将显示当前进程的进程ID,$?将显示脚本的退出状态码:
```
Hello,<当前用户名>,the output of this script are as follows:
The script name is : test.sh
The first param of the script is : param1
The second param of the script is : param2
The tenth param of the script is : param10
All the params you input are : param1 param2 param3 param4 param5
All the params you input are : param1 param2 param3 param4 param5
The number of the params you input are: 5
The process ID for this script is : <当前进程的进程ID>
The exit status of this script is : <脚本的退出状态码>
```
其中,param10是因为${10}需要用花括号括起来,否则会被解释为$1后面的0。
