I'm working on a node script that will do some stuff with execa package. Basically I want that script to change directory to certain path and then run another mand within that path.

I did it like that:

execamand('cd /some/dir && pwd'); 

But pwd mand won't execute for some reason, though it finishes successfully.

What could be the reason, the mand after && won't execute, and is there any other way to manage that task?

Thanks!

• 2 docs say: "The shell option must be used if the mand uses shell-specific features, as opposed to being a simple file followed by its arguments." I'm guessing && might be considered a shell-specific feature? – David784 Commented Feb 11, 2020 at 18:05

The question you should be asking is "How do I run a mand with a different working directory?", which will give you the simple, robust, cross-platform solution of using the cwd option:

execa.mand('pwd', { cwd: '/some/dir' });

If you instead want to acplish this task with &&, you can do that by invoking a shell. This is more fragile and platform specific:

execa('sh', ['-c', 'cd /some/dir && pwd']);
