                          I have this env file

 - 1.env contents:

    BARF_BAG=1

then another env file:

 - 2.env contents:

    BARF_BAG=2

I run comm and diff on the files to see the difference:

    #!/usr/bin/env bash
    
    (
      set -e;
    
      first_env_file="$1"
      second_env_file="$2"
    
      if ! test -f "$first_env_file"; then
         echo 'first arg must be an env file';
         exit 1;
      fi
    
      if ! test -f "$second_env_file"; then
         echo 'second arg must be an env file';
         exit 1;
      fi
    
      echo -e '\n'
      echo -e 'displaying results from diff tool:'
      diff <(. "$first_env_file"; env | sort) <(. "$second_env_file"; env | sort) || true
      echo -e '\n'
      echo 'displaying results from comm tool:'
      comm -3 <(. "$first_env_file"; env | sort ) <(. "$second_env_file"; env | sort) || true
      echo 'finished diffing env files.'
    )

and I get nothing, just:

    displaying results from diff tool:
    
    displaying results from comm tool:
    finished diffing env files.

what gives?
