Golang: extract data with Regex

Question

I\'m trying to extract whatever data inside ${}.

For example, the data extracted from this string should be abc.

git commit -m

You can try with this too,

re := regexp.MustCompile("\\$\\{(.*?)\\}")

str := "git commit -m '${abc}'"
res := re.FindAllStringSubmatch(str, 1)
for i := range res {
    //like Java: match.group(1)
    fmt.Println("Message :", res[i][1])
}
