Setting NODE_PATH in command line via script

/home/karl/myapp/path.sh:

#!/bin/bash
currentDir=$(
  cd $(dirname "$0")
  pwd
) 

echo $currentDir

The script above echos the absolute path. I'd like to set the NODE_PATH variable as seen below with the echo'd value.

NODE_PATH=path.sh ./node_modules/.bin/mocha -r babel-register -r babel-polyfill --reporter spec

At the moment NODE_PATH is actually set to the string "path.sh" and not the absolute path that it echos.

So I'd like the result to be the same as NODE_PATH=/home/karl/myapp/ ./node_modules/.bin/mocha -r babel-register -r babel-polyfill --reporter spec as an example.

Any ideas?

I've also tried the following: bash path.sh | NODE_PATH="$currentDir" ./node_modules/.bin/mocha -r babel-register -r babel-polyfill --reporter spec

With help from Arif Khans answer I was able to come up with the three following:

NODE_PATH="$(dirname $(readlink -f ./path.sh))" ./node_modules/.bin/mocha -r babel-register -r babel-polyfill --reporter spec

NODE_PATH="$(bash path.sh)" ./node_modules/.bin/mocha -r babel-register -r babel-polyfill --reporter spec

NODE_PATH="$(pwd)" ./node_modules/.bin/mocha -r babel-register -r babel-polyfill --reporter spec

you can do it by executing the below command:

NODE_PATH=`./p.sh`'./node_modules/.bin/mocha -r babel-register -r babel-polyfill --reporter spec'

whatever is in between `` is basically executing that particular command and then append what is needed.

By default, it will be consider as string. You need to inside $(COMMAND) like in your case "$(sh path.sh)" . So complete command will be 

NODE_PATH="$(sh path.sh)" ./node_modules/.bin/mocha -r babel-register -r babel-polyfill --reporter spec

Hope this will help you
