For Windows. You need to execute. echo from a command processor -- "cmd"

const command = new Deno.Command("cmd", {
   args: ["/c", "echo","hello world"],
   stdin: "piped",
   stdout: "piped"
 }).spawn();
 
 let result = await command.output();
 const textDecoder = new TextDecoder();
 console.log(textDecoder.decode(result.stdout));

const command = new Deno.Command("cmd", {
   args: ["/c", "echo","hello world"],
   stdin: "piped",
   stdout: "piped"
 }).spawn();
 
 let result = await command.output();
 const textDecoder = new TextDecoder();
 console.log(textDecoder.decode(result.stdout));

@Altair 680b i am quite new to this . could you help me with one last doubt i have i want to npm init (for example ) in the current working directory

FYI many linux commands are just executables. In Windows, they are methods of the command processor. I was unable to spawn 'npm' Not sure why. Try asking the #Deno AI Helper

i tried using , ls , pwd in

args: ["/c", "ls"],

args: ["/c", "ls"],

'ls' is not recognized as an internal or external command, operable program or batch file. @Deno AI Helper

Also, you may want to try DAX -- written by a Deno core team member. https://github.com/dsherret/dax
