+parser.add_argument(

Nit: can be action="store_true"

vars = [b"%s=%s" % (k.encode('ascii'), filter(v).encode('ascii'))

for k, v in env]

-out.write(b" ".join(vars))
+
+# Print variables on out
+if args.line is False:

Nit: not args.line

+ vars = ["%s=%s" % (k, filter(v)) for k, v in env]

Why not reuse the vars constructed above? It's carefully written to be
Python3 safe.

Will update for the Nits

It's a bad resolution of a merge conflict, I will remote the line, nice catch
