Function quoteCommand

cli/connhelper/ssh/ssh.go:167–183

quoteCommand returns the remote command to run using the ssh connection as a single string, quoting values where needed because ssh executes these in a POSIX shell.

(commandAndArgs ...string)

// as a single string, quoting values where needed because ssh executes
// these in a POSIX shell.
func quoteCommand(commandAndArgs ...string) (string, error) {
	var quotedCmd string
	for i, arg := range commandAndArgs {
		a, err := syntax.Quote(arg, syntax.LangPOSIX)
		if err != nil {
			return "", fmt.Errorf("invalid argument: %w", err)
		}
		if i == 0 {
			quotedCmd = a
			continue
		}
		quotedCmd += " " + a
	}
	// each part is quoted appropriately, so now we'll have a full
	// shell command to pass off to "ssh"
	return quotedCmd, nil
