I'm used to having tab-completion for mysql keywords, database names etc in mysql, but in my freshly installed mysql (via 'apt-get install mysql-server') it only works for table names, not database names.
I am supplying the --auto-rehash option when starting the mysql command line client interface. I'm aware that I can set this as a default via my.cnf, but I want to get it working first.
The mysql docs tell me that the auto-rehash feature "requires a MySQL client that is compiled with the readline library."
'aptitude show mysql-client' tells me that I have 5.5.43-0ubuntu0.14.04.1.
For debugging purposes, how can I know if my mysql-client has readline, and if not, how do I get one that does?
