Yeah, the >>> implies you're at the Python REPL, and the page I linked you
to is a few pages into learning to use Fabric; so it's going to assume you
installed the library. If you already know Tcl/Expect, I'm sure you can
bang out a script to do your task at hand, and if you need it now and don't
have time to pick up Python and Fabric on top of it, that sounds like your
best option.
When you get some spare time, there are a bunch of great tutorials that can
help you with the syntax (which may be easy), and also how Python is
loading/running scripts/packages/modules (which is usually less obvious),
which Fabric then uses to find a 'fabfile' package. I haven't heard of
Tidelift, but yeah, I feel your pain that a lot of training sites which
were once free are now pay-only (or very expertly hide the free options,
*coughcodecademycough*). Fortunately, the gigantic popularity of Python
means new, free content is always being created, so some searching may help
(I'm hesitant to cite anything in particular because I haven't looked at
any recently)
I was curious what examples/documentation you were following along with
originally, however, because it seemed incomplete, even for the 3-4 lines
that you had. It would be nice to correct it so others aren't misled in the
future.
