🔒 CanUseSudo

Parameters

Parameter	Type	Description
None	—	Package-level function, takes no parameters

Return Value

• bool: true means sudo exists in the PATH; false means it is unavailable.

Example

package main

import (
	"fmt"

	"github.com/scagogogo/composer-skills/pkg/installer"
)

func main() {
	if installer.CanUseSudo() {
		fmt.Println("sudo is available for privilege escalation")
	} else {
		fmt.Println("sudo is unavailable; write to user-writable directories")
	}

Advanced

• Implemented as whether exec.LookPath("sudo") succeeds. 🛠️
• The result can be used to decide the value of Config.UseSudo, which in turn affects the behavior of Install, Uninstall, and similar methods. 🔗
• On Windows it typically returns false; use administrator privileges instead of sudo. 🚫
