/usr/bin/byobu-select-session has bogus #! line

Hmm, so this bug and https://bugs.launchpad.net/byobu/+bug/996559 are in direct opposition...

What's the right answer here? I have no particular opinion...

Ideally, your development (i.e. vcs trunk) version would use /usr/bin/env but
the distro-installed version would use /usr/bin/python. I'm not particularly
sympathetic to someone who wants to run the distro-installed version of byobu
with a from-source installation of Python. But even in those cases, they can
probably invoke the script explicitly, e.g.

$ /usr/local/bin/python /usr/bin/byobu

The usage of "env" has been removed from the shebang line(s) again.

This causes trouble when there is no /usr/bin/python (e.g. on stripped down system, with Python only in /usr/local or /opt).

What do you think about introducing a BYOBU_PYTHON variable, which could default to /usr/bin/python and would be used to "exec" the Python based byobu scripts, like "byobu-select-session"?

I know that it's possible to create a symlink /usr/bin/python, but that would be gone after an update.

and btw: running byobu directly using Python will result in a syntax error, because bin/byobu itself is a shell script. There are only a few (2?!) scripts written in Python.

Re-Opening: see previous comment.

While I think that Barry's point to use /usr/bin/python makes sense for the distro package, it should/could use "/usr/bin/env python" for custom installations and the source checkout.

@Barry: do you agree?

Sorry, Daniel. I appreciate the bug and the feedback, but this isn't something I'm going to fix upstream in Byobu. Users who want to use a different Python interpreter will need to edit these 2 lines in their custom installations. Sorry.

This bug was fixed in the package byobu - 5.31-0ubuntu1
