How? If two versions of each application with different shebangs are installed: /usr/bin/foo.python3 /usr/bin/foo.python2 /usr/bin/foo -> /usr/bin/foo.python3 /usr/bin/bar.python2 /usr/bin/bar.python3 /usr/bin/bar -> /usr/bin/bar.python2 I guess, this is also possible: Each application has a unique shebang, e.g. for /usr/bin/bar: #! /usr/bin/python.bar then /usr/bin/python.bar can be made to either point to /usr/bin/python or /usr/bin/python3 using alternatives.
