Answer 1

in local FS :

/home/username/some/path/Query1.q (.hql) -- inside it query is "show databases;"

(give all three Queries in one file if needed)

from shell $:

user@hostname $ $HIVE_HOME/bin/hive -f /home/username/some/path/Query1.q
OK
database_name
db
default
financials
mydb

from hive CLi :

hive> source /home/username/some/path/Query1.q
