Golang…字符串类型的arg函数

Question

Why i cant put args in function

func ex(c string,ex ...string) { exec.Command(c,ex) }

get error cannot use args (type []string) as type string. Why?

Answer 1

You can use: ex... in the statement exec.Command(c,ex...) instead of just ex

Below as an example:

func ex(c string,ex ...string) { exec.Command(c,ex...) }
