Function cmdOutputDirErr

dev/devcam/hook.go:277–289

cmdOutputDirErr runs the command line in dir, returning its output and any error results. NOTE: cmdOutputDirErr must be used only to run commands that read state, not for commands that make changes. Commands that make changes should be run using runDirErr so that the -v and -n flags apply to them.

(dir, command string, args ...string)

// not for commands that make changes. Commands that make changes
// should be run using runDirErr so that the -v and -n flags apply to them.
func cmdOutputDirErr(dir, command string, args ...string) (string, error) {
	// NOTE: We only show these non-state-modifying commands with -v -v.
	// Otherwise things like 'git sync -v' show all our internal "find out about
	// the git repo" commands, which is confusing if you are just trying to find
	// out what git sync means.

	if dir != "." {
		cmd.Dir = dir

	b, err := cmd.CombinedOutput()
