@pgollucci Want to pick this one?

Something like this?

Task Level

task.cwd('foo');
task.exec('ls');
task.exec('echo bar');

results in

(cd foo ; ls)
(cd foo; echo bar)

exec() level

task.exec('ls', 'foo');

results in

(cd foo ; ls)

other

• where exec() would override the task if set at Task level
• if exec() dir is unset it would check Task, use if set otherwise plain

Give #356 That API won't work for exec()

task.exec("ls", {
  args?: [],
  cwd?: foo,
});

Yes that's what I had in mind.

And also support at the Task level so it applies to all commands (unless they override):

p.addTask('foo', {
  cwd: 'relative/sir'
});
