修改 bash 脚本本身的命令行参数
Modify command line arguments in bash script itself
我可以在 bash 脚本本身中更改命令行参数(如 $1、$2)吗?
我试过这样的东西:
='a'
read var
=$var
内置设置可让您执行此操作。
来自the spec:
The remaining arguments shall be assigned in order to the positional parameters.
The remaining N arguments are positional parameters and are assigned, in order, to , , … $N.
