You MUST exit first to see the effect!

Currently I can use DB Browser for SQLite to open an encrypted DB file with password on Mac.
The options as per image:
Raw key (start with 0x...)
SQLCipher 3 defaults
I would like to open this file using command line instead of DB Browser.
Tried follow commands but seems no luck so far.

sqlite> pragma key="0xMyKey";
ok
sqlite> .tables

Appreciate the help in advance so that I can use command line to access or export sqlite db just like mysql (mysql -u ... & mysqldump).
Found the documentation via this link: https://www.zetetic.net/sqlcipher/sqlcipher-api/

I am new to sqlite. I want to inspect existing read only database like below.

Error: attempt to write a readonly database
I don't get it. Do I need write access to simply query sqlite database? I need a few poiters here
I read in https://sqlite.org/wal.html about immutable query parameter. If I replace path with URI with that query parameter, then I can inspect the read-only database.

For example in DB2 there is a "user" that will give you who is logged in and performing the queries. And no, there is no "logging into DB2" I only login once to gain access to the whole OS (IBM i 7.1).
declare global temporary table XYZ ( DUMMY char(1))
Table XYZ created in QTEMP.
insert into XYZ values('1')
1 rows inserted in XYZ in QTEMP.
select user from XYZ
Output:
....+....1....+...
USER
"my-login-user-id-is-shown-here"
******** End of data ********
in sqlite3:

Thanks in advance!
SQLite is a file-based database; it neither cares nor knows about OS users.
I tried this (running sqlite from the unix shell) and found it to be an acceptable solution, but I will like to be able to do the same from within the sqlite command shell.

I am trying to create a database in SQLite. I am getting the error as above. Please help
sqlite3 DatabaseName.db is what you'd use at the command line, not once you've already started the shell. Running that at command line will open it in the shell with the empty database already open.
When your prompt is sqlite>, you're already in the shell.
Here are some docs: http://sqlite.org/sqlite.html
I know this is the stupid question but i am so confused so please help me.
The question is when i use sqlite command line and make a database.
SQLite version 3.6.22
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> sqlite3 mydata.db
---> (now i terminate it using ;)
And now i craete tables and use .output filename and then select * from tb(table)
The file craeted nowhere!!
So please let me know where file craeted.
Or any other method to craete sqlite database file.
Thanks in advance.
What's wrong with this? It perfectly works and both mydatabase.db and foo_contents.txt exist.
