Usage: mysql [OPTIONS] [database]

-?, --help Display this help and exit.

-I, --help Synonym for -?

--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.

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

(Enables --silent.)

--character-sets-dir=name

Directory for character set files.

--column-type-info Display column type information.

-c, --comments Preserve comments. Send comments to the server. The

default is --skip-comments (discard comments), enable

with --comments.

-C, --compress Use compression in server/client protocol.

-#, --debug[=#] This is a non-debug version. Catch this and exit.

--debug-check Check memory and open file usage at exit.

-T, --debug-info Print some debug info at exit.

-D, --database=name Database to use.

--default-character-set=name

Set the default character set.

--delimiter=name Delimiter to be used.

-e, --execute=name Execute command and quit. (Disables --force and history

file.)

-E, --vertical Print the output of a query (rows) vertically.

-f, --force Continue even if we get an SQL error.

-G, --named-commands

Enable named commands. Named commands mean this program's

internal commands; see mysql> help . When enabled, the

named commands can be used from any line of the query,

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

with a semicolon (;). Since version 10.9, the client now

starts with this option ENABLED by default. Disable with

'-G'. Long format commands still work from the first

line. WARNING: option deprecated; use

--disable-named-commands instead.

-i, --ignore-spaces Ignore space after function names.

--local-infile Enable/disable LOAD DATA LOCAL INFILE.

-b, --no-beep Turn off beep on error.

-h, --host=name Connect to host.

-H, --html Produce HTML output.

-X, --xml Produce XML output.

-n, --unbuffered Flush buffer after each query.

--column-names Write column names in results.

-N, --skip-column-names

Don't write column names in results.

-O, --set-variable=name

Change the value of a variable. Please note that this

option is deprecated; you can set variables directly with

--variable-name=value.

--sigint-ignore Ignore SIGINT (CTRL-C).

-o, --one-database Ignore statements except those that occur while the

default database is the one named at the command line.

--pager[=name] Pager to use to display results. If you don't supply an

option, the default pager is taken from your ENV variable

PAGER. Valid pagers are less, more, cat [> filename],

etc. See interactive help (h) also. This option does not

work in batch mode. Disable with --disable-pager. This

option is disabled by default.

--no-pager Disable pager and print to stdout. See interactive help

(h) also. WARNING: option deprecated; use

--disable-pager instead.

-p, --password[=name]

Password to use when connecting to server. If password is

not given it's asked from the tty.

-P, --port=# Port number to use for connection or 0 for default to, in

order of preference, my.cnf, $MYSQL_TCP_PORT,

/etc/services, built-in default (3306).

--prompt=name Set the mysql prompt to this value.

--protocol=name The protocol to use for connection (tcp, socket, pipe,

memory).

-q, --quick Don't cache result, print it row by row. This may slow

down the server if the output is suspended. Doesn't use

history file.

--ssl-key=name X509 key in PEM format (implies --ssl).

--ssl-verify-server-cert

Verify server's "Common Name" in its cert against

hostname used when connecting. This option is disabled by

default.

-t, --table Output in table format.

--tee=name Append everything into outfile. See interactive help (h)

also. Does not work in batch mode. Disable with

--disable-tee. This option is disabled by default.

--no-tee Disable outfile. See interactive help (h) also. WARNING:

Option deprecated; use --disable-tee instead.

-u, --user=name User for login if not current user.

-U, --safe-updates Only allow UPDATE and DELETE that uses keys.

-U, --i-am-a-dummy Synonym for option --safe-updates, -U.

-v, --verbose Write more. (-v -v -v gives the table output format).

-V, --version Output version information and exit.

-w, --wait Wait and retry if connection is down.

--connect_timeout=# Number of seconds before connection timeout.

The maximum packet length to send to or receive from

server.
