在Go中转义反引号（exec.Command中使用的字符串）

Question

Given this code, I can't figure out how to escape the backtick.

var (
    MY_STRING = "something`something"
)
cmd := fmt.Sprintf("MY_ENV=%q;", MY_STRING)
out, err := exec.Command("bash", "-c", cmd).CombinedOutput()
// results in MY_ENV="something`something" ie unfinished input

I've tried the below but it results in "unknown escape sequence". It does work in the shell obviously. I've also tried to combine strings and raw string literals but with no success. How can I escape the backtick please?

var (
    MY_STRING = "something\`something"
)

Use ' to escape ` in Bourne shells. And no need to quote the string.

MY_STRING := "something'`'something"
cmd := fmt.Sprintf("MY_ENV=%s;", MY_STRING)
out, err := exec.Command("bash", "-c", cmd).CombinedOutput()
