How to properly run bash script from nodejs (Problem with cd transitions)?

Question

bash

There is bash, for example

cd ../myapp
runmycmd param1 param2
cd dir1/dir2
...
cd ../path

If you run from the console - everything is ok. If I run it from a nodejs script, I get

cd: myapp: No such file or directory

I run it like this:

child = exec("/bin/bash " + 'bash.sh params',
    function (error, stdout, stderr) {
        ...
    }
);

What is missing?

Answer 1

Specify the full path, not the relative path:

cd /home/user/myapp
...

Answer 2

cd ../myapp
What's missing?

Knowing which directory is the current one?
