Problem with bash shell needed for my python project

[Larz60+]

I settled for:

#!/bin/bash

OSMOSIS="/usr/bin/osmosis"
OSFILTER="place=city,town,village,hamlet,suburb,borough,municipality"
OCFILTER="@id @lat @lon name"

cd Alabama
$OSMOSIS --read-pbf "Alabama-Latest.Osm.Pbf" --tf reject-relations --tf reject-ways --tf accept-nodes $OSFILTER --write-xml "AlabamaCities.pbf"
osmconvert AlabamaCities.pbf --csv="$OCFILTER" -o="AlabamaCities.csv"
cd ..

which gets the job done for now. I am in the process of converting to 100% python now.
