--auto-rehash       Enable automatic rehashing. One doesn't need to use

'rehash' to get table and field completion, but startup

and reconnecting may take a longer time. Disable with

--disable-auto-rehash.

-A, --no-auto-rehash 

No automatic rehashing. One has to use 'rehash' to get

table and field completion. This gives a quicker start of

mysql and disables rehashing on reconnect. WARNING:

options deprecated; use --disable-auto-rehash instead.

-B, --batch         Don't use history file. Disable interactive behavior.

(Enables --silent)

--character-sets-dir=name 

Directory where character sets are.

--default-character-set=name

otherwise only from the first line, before an enter.

Disable with --disable-named-commands. This option is

disabled by default.

-g, --no-named-commands 

Named commands are disabled. Use \* form only, or use

named commands only in the beginning of a line ending
