Is there such a thing?
Of course I know and use the sqlite3 command line utility but that's just a way of running SQL from the command line. What I want is some sort of wrapper/utility that reads the data from the database, presents it to me in some sort of reasonably editable format and then, when I've changed something writes it back.
I'd be happy enough with a simple browse facility plus some sort of way of changing individual fields. So "dbedit xyz.db table1" just presents me with the data in some sort of reasonable, scrollable column layout. Then some sort of command says "change column 10, row 4 to 'ABCDE'".
