Cmd.Command

Overview

Command builds a command (child_process.spawn / execFile).

If you are coming from Node.js, the closest pattern is spawn(cmd, args).

Method on Cmd — call it on a value of that type after constructing or receiving one from a constructor.

Signature

func Command(ctx context.Context, name string, args ...string) *Cmd

Compare: Node.js · Standard Go · gox

Node.js

spawn('ls', ['-la']);

Standard Go

cmd := exec.CommandContext(ctx, name, args...)
out, err := cmd.CombinedOutput()

gox

import "github.com/sahilkhaire/gox/exec"

cmd := exec.Command(ctx, "ls", "-la")

Example

import "github.com/sahilkhaire/gox/exec"

cmd := exec.Command(ctx, "ls", "-la")

Tips

Pass context.Context as the first argument so cancellation and deadlines propagate correctly.

Standard library alternative

Use the standard library directly:

cmd := exec.CommandContext(ctx, name, args...)
out, err := cmd.CombinedOutput()
