shellexec

Package shellexec provides cross-platform shell-like command execution. It supports a small subset of the Shell Command Language related to executing of commands. Package shellexec isn't a replacement for os/exec. It's rather just a convenience package for use-cases that require/prefer having just a single string to define the command to execute.

	run(`VARIABLE=assignment, X=3 env`)

	run(`echo The goal is to support a really \*small\* subset`)
	run(`echo of the Shell language while being 100\% compatible.`)
}

func run(command string) {
	cmd, err := shellexec.Command(command)
	if err != nil {
		log.Fatal(err)
	}
	cmd.Stdin = os.Stdin
	cmd.Stdout = os.Stdout
	cmd.Stderr = os.Stderr

	if err := cmd.Run(); err != nil {
