What if you add ECHO $<your_varible_for_output_here> expressvpn status
Also I’m not sure which Distro you are using but In Debian there’s a program “DocBook” that gives all your documentation a single point of access (a web page) and I downloaded “Advanced Bash-Scripting Guide: An in-depth exploration of the art of shell scripting” and it’s free to download and use. That might be a good thing to get too.
