bash-db's Issues

Can't delete the key including space. (but can created it)

Additional db file being created

Hello. I am getting another db file being created with same name appended with a r when updating value.

For example when I insert some data
./db.sh put testdb hello world
a file named testdb is created.
When I update the data using
./db.sh put testdb hello world
another file named testdbr is created.

I was wondering that was this intended.
I checked the code and did not found what part caused this.
