File execution in Unix

Question

base
   └──────install
   └──────setup
              └───myfile

Suppose this is a part of my directory structure in Unix. Is there any difference between these two:

1)

base/setup$ myfile

2)

base/install$ ../setup/myfile

I was trying to install something, and the second gave me some library dependency errors. I thought that these two methods are the same. Why is not that so?

Answer 1

base/setup/myfile and base/install/../setup/myfile are the same file. The only explanation I can think of is that base/setup/myfile is referencing a file with a path relative to your current working directory (e.g: run ./modules/pre-setup) - in which case it may make a difference where you are when you run the script.

Answer 2

it may not have worked as myfile could be trying to call or use things in current directory expecting to be located in the base/setup directory but you are in the base/install directory.
