How to find database is UP or DOWN using Linux/Unix command.

(I am not asking Instance up or down)
(I am not asking Oracle commands like v$database)
I am asking OS command to know Database is up or down.

Thanks in advance

Not possible.
With ps -ef , you check the availability of instance.
The instance can be up but the database could still be down or just mounted.
Only way is to login to database and issue a query.

I am confused at this point , how can we start the instance without starting DB?

(May be I dont know )!!!
