At the top of all my Perl 6 programs, I place

You may want to `zef install Readline` or `zef install
Linenoise` or use rlwrap for a line editor
To exit type 'exit' or '^D'
Is this suppose to happen?
Yes. The "shebang" line
#!/usr/bin/env perl6
means "use the env to find the perl6 exe and run it" just as:
#!/usr/local/bin/perl6
does, only that's more specific. So, you're seeing P6 in interactive
mode, and it's advising you that w/o Linenoise or Readline, you won't be
able to use "<up arrow>" etc for editing in interactive mode.
$ man env
NAME
env - run a program in a modified environment
You can do
$ which perl6
to see where the exe might be found, too.
Thank you!
I had to use find to located it. Then I created links.
# ls -s /opt/rakudo-pkg/bin/zef /usr/bin/zef
# ls -s /opt/rakudo-pkg/bin/perl6 /usr/bin/perl6
Then which found it.
I use env exclusively as the Fedora repo and git use
different paths and I never know what one my customers
are using
