How to Set Path Variables

[Editing this post, as the topic becomes more clear]

Does anyone know how to set the path variables for a Mac OS?

Current folder structure:

  /
     /Applications
             /[a lot of applications]
            /Postgres.app
                       /Contents
                               /Versions
                                        /12
                                             /bin
                                                  /psql
   /Users
           /myName
                  /Applications
                        /[nothing, except a couple hidden files]

Right now, if I run the command psql, I am getting “command not found”
If I type the full path "/Applications/Postgres.app/Contents/Versions/12/bin/psql, it works. But typing this every time is not practical.

If I run “git” that command is available, or “code .”

Also, I installed “netlify-cli” globally with “npm install -g netlify-cli”, but when I run “netlify-cli”, I get “command not found” and I don’t know where to find it in my system

… So, something is working correctly with my paths, and something is not. I don’t know how to fix the problem, without messing up other paths.

Does anyone know how I could find out where “netlify-cli” got installed and fix my paths to “netlify-cli” and “psql” without messing up any other paths?

Thanks for any pointers!

To clarify, cd ~ does indeed take you to your user directory. To go to root, you’d use cd /.

The command

export PATH=/Applications/Postgres.app/Contents/Versions/12/bin

might be what you are looking for to set the path?

I’m not super familiar with Postqresql, unfortunately.

Thanks for that tip. (I took out the part about postgresql, because it turns out it was a type-o. I mainly need to learn about paths and permissions).

Found this: You can run npm list -g to see which global libraries are installed and where they’re located.
