Assumpte: [exim] Pipe transport and script (shebang)
Hi all,

recently i decide to improve my pipe transport for reports processing
to allow relative commands and i go into problems. It was worked
without problems with absolute script path for long time. I solved it,
but i want to know why that happens...

The only changes which i did, are -- i add path option to transport:

    path = /my/scripts/path


I changed command name to relative (without path) in redirect router:

    data = |script_name.py one_arg


After message arrived, it fail to run that script, with output:

    reports_pipe transport output: /usr/bin/env: 'python3': No such
    file or directory


I had that in shebang, after i changed shebang to point directly to
/usr/bin/python3, it starts to work again.

I tried to emulate that from shell by setting PATH variable to the same
value as in transport, then i tried to clear it at all, but scripts runs
without problem, i tried to find something in env's man page, but i
fail...

Thus i am curios why that was not problem with full script path but it
is problem with relative script path. Can please someone explain me
that?

regards
