Save the file in your home directory. For example as ~/.runwithenv.sh and make it executable (chmod u+x ~/.runwithenv.sh). Finally add the following alias at the end of your ~/.bashrc:

alias wenv=~/.runwithenv.sh

The script expects the .env file to be in the same path as your executable.

The .env file should have the following format:

ENV_VARIABLE_NAME_A=ENV_VALUE_A
ENV_VARIABLE_NAME_B=ENV_VALUE_B

and so on. Now you're able to execute scripts with the environment specified by invoking any executable like this:

wenv ./myprogram
