Any help appreciated.

We can use Environment Variables First lets understand how they work, the ways we can configure them, and what the differences are. The ArchWiki goes into detail here: https://wiki.archlinux.org/index.php/Environment_variables#Defining_variables Variables can be defined for each command we run. In the sudoedit example that means we can manually tell it to use our choice of editor by doing something …

Who’s “we”? What “system”? You have a server running Manjaro that includes AUR packages for your customers?
