How to add export statement in a bash_profile file?

bash, linux

Solution

Simply write `export AS='name'` anywhere in your `~/.bash_profile` file:

# Append to the end of the file
$ echo "export AS='name'" >> ~/.bash_profile

# Update shell 
$ source ~/.bash_profile

This first command adds the line you want to the file (or just use a text editor) the second updates the shells with the new variable.

Problem

I'm trying to learn that if I have to add export statement to set a variable in a bash_profile file . How would I do that ? For example if I have to add export AX = 'name' then should I simply write it at the end of file or do I need to write anything else as well
