package main
import (
"bytes"
"context"
"log"
"os/exec"
"time"
)
func main() {
var stdout bytes.Buffer
ctx, cancel := context.WithTimeout(context.Background(), time.Second)
defer cancel()
cmd := exec.CommandContext(ctx, "/bin/sh", "-c", "sleep 10; echo foo")
cmd.Stdout = &stdout
err := cmd.Run()
log.Printf("%s, %s, '%s'", err, ctx.Err(), stdout.String())
}
This runs for 10 seconds, but I was expecting 1 second. Can someone help me
understand what is happening? I think it has something to do with the
stdout bytes.Buffer?
