I'm trying to work on a PoC with adding exec.Command's to cli plugin, however I'm struggling with how to get it to accept user input with the command. I admit I am fairly new to Go, coming from PHP and Bash scripting so...I am sure I'm missing something very basic here and it's a little embarrassing.
I've tried setting variables, adding the variables to the output, adding in bufio, and trying to prompt with no luck.
out, err := exec.Command("mtr", "-c", "10", "-r", destIP).Output()
was the most recent fail...
type Mtr struct{}
func (m *Mtr) Run(command []string, context plugin.PluginContext, ui terminal.UI) {
// var destIP string - commented out simply so I could rebuild the file and get the plugin working again.
ui.Say("")
ui.Say(terminal.AdvisoryColor("Wait while we run a traceroute..."))
ui.Say("")
out, err := exec.Command("mtr", "-c", "10", "-r").Output()
if err != nil {
ui.Say(fmt.Sprintf("%s", err))
}
output := string(out[:])
table := ui.Table([]string{"", ""})
table.Add("", output)
table.Print()
I literally just want it to be able to accept something like this
mainprogram plugin mtr Currently I have it set to just force Google, but that is not really what I want out of this...
out, err := exec.Command("mtr", "-c", "10", "-r", "8.8.8.8").Output()
Current output with the botched attempts yields -
Shawns-MBP-2:directoryhere $ mainprog plugin mtr 4.4.4.4
Wait while we run a traceroute...
Shawns-MBP-2:directoryhere$
With the forced Google DNS, it obviously shows -
Shawns-MBP-2:directoryhere $ mainprog plugin mtr
Wait while we run a traceroute...
