exec.Command输出中的“ Bad value”

Question

My go language program prints "Bad value for option -n 1, valid range is from 1 to 4294967295." when trying to ping using below code snippet

result , err := exec.Command("ping","-n 1", "-w 1", ip).Output()
fmt.Printf("%s
", result)

When doing it from cmd in Win i.e. 'ping -n 1 -w 1 8.8.8.8' is fine

Answer 1

You need to separate the -n and -w flags and their values into separate arguments (your shell was already doing this):

result , err := exec.Command("ping", "-n", "1", "-w", "1", ip).Output()
