I work with a lot of different Concourse servers that have a variety of versions. fly rejects working with servers that are off to much. Therefore I have fly-3.14.1, fly-4.2.3 etc. on my machine.

But many set-pipeline scripts assume that a single fly command exists and that it magically is of the right version. So I need to switch; preferably per directory or per shell.

Did not work

• Shell aliases are never exported, so that a set-pipeline script does not know about the alias.
• I use ZSH, where functions cannot be exported.

Works
