Thanks so much for responding
At this point, I've fiddled so much with the PATH, I'm nowhere. Can't even
run that log command you suggested.
So, I'm really curious: what environments are people working in? SSH to
remote Ubuntu, like E2? macboook? Anyone having success scripting on the
windows side?
I had hoped to have my desktop also serve as my local dev environment for
postgres/postgis/qgis/tilemill... I'm pretty much there, except on the
windows side I could only use the GUI, and so far no luck on the command
line side of things.... and the latter was offered as a solution to some of
the barriers I was experiencing.
The space in "Program Files" is an issue, and escaping it doesn't seem to
work. Neither does quoting it. I've done a bunch of googling, and maybe I'm
just too tired to get there tonight.
