executil

Introduction

This package provides some convenient wrappers around os/exec. Specifically it solves the problem of running external processes until they complete while continously streaming stdout and stderr to an io.Writer of your choice. This package also makes piping other commands in sequence convenient.

Examples

cmd1 := exec.Command("echo", "hello world")
cmd2 := exec.Command("cat")
stdout, stderr, err := StartWaitPipe(nil, cmd1, cmd2)
if err != nil {
    fmt.Fprintf(os.Stderr, "%v", err)
} else {
    fmt.Printf("%s", stdout)
}

This is equivalent to running the following in the a shell

echo "hello world" | cat

Run all tests recursively with stdout and stderr output to shell

go test ./... -v
