Golang character escape in exec.Command

Hello I have a command line wrapper for exec.Command function as below :

func GenCmd(cmdline string) *exec.Cmd {
	fmt.Println("command is ", cmdline)
	// splitting head => g++ parts => rest of the command
	parts := strings.Fields(cmdline)

	head := parts[0]
	parts = parts[1:len(parts)]

	// exec cmd & collect output
	cmd := exec.Command(head, parts...)
	fmt.Printf("Generated comdline : %s", cmd)
	return cmd
}

func exeCmd(cmdline string, wg *sync.WaitGroup) {
	cmd := GenCmd(cmdline)
	out, err := cmd.Output()
	if err != nil {
		fmt.Printf("%s", err)
	}
	fmt.Printf("%s", out)
	wg.Done() // signal to waitgroup this goroutine complete
}

I want to call a curl command as below in my wrapper , origin curl command as below:

curl -G https://api.github.com/search/repositories       \
    --data-urlencode "q=created:>`date -v-7d '+%Y-%m-%d'`" \
    --data-urlencode "sort=stars"                          \
    --data-urlencode "order=desc"                          \
    -H "Accept: application/vnd.github.preview"            \
    | jq ".items[0,1,2] | {name, description, language, watchers_count, html_url}"

But seems like character - ` both need to be escaped at command

`date -v-7d '+%Y-%m-%d'`

Any idead how can I do that ?

main function below:

func main() {
	x := []string{
		`curl -G https://api.github.com/search/repositories ` +
			`--data-urlencode "q=created:>\`date -v-7d '+%Y-%m-%d'\`" --data-urlencode 'sort=stars' --data-urlencode 'order=asc'` +
			`-H 'Accept: application/vnd.github.preview'` +
            `| jq ".items[0,1,2] | {name, description, language, watchers_count, html_url}"`
	}

	cmdCnt := len(x)
	wg := new(sync.WaitGroup)
	wg.Add(cmdCnt)

	for _, cmd := range x {
		go exeCmd(cmd, wg) // empty string output to stdout
	}

	wg.Wait()
}

Here is full golang code

You cannot escape backticks inside backticks but you can build long string like this:

`first 
 part ` + "`second part`" + `…`
