(Defaults to on; use --skip-auto-rehash to disable.)

//自动补全功能。按tab键补全

-A, --no-auto-rehash

table and field completion. This gives a quicker start of

mysql and disables rehashing on reconnect.

--auto-vertical-output

Automatically switch to vertical output mode if the

result is wider than the terminal width.

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

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

--max-join-size=# Automatic limit for rows in a join when using

--safe-updates.

--secure-auth Refuse client connecting to server if it uses old

--histignore=name A colon-separated list of patterns to keep statements

from getting logged into mysql history.

translated to '\n'. This switch turns off both features,

and also turns off parsing of all clientcommands except

\C and DELIMITER, in non-interactive mode (for input

piped to mysql or loaded using the 'source' command).

This is necessary when processing output from mysqlbinlog

that may contain blobs.

--connect-expired-password

Notify the server that this client is prepared to handle

expired password sandbox mode.

Default options are read from the following files in the given order:

/etc/my.cnf /etc/mysql/my.cnf /usr/local/mysql/etc/my.cnf ~/.my.cnf

The following groups are read: mysql client

The following options may be given as the first argument:

--print-defaults Print the program argument list and exit.

--no-defaults Don't read default options from any option file,

except for login file.

--defaults-file=# Only read default options from the given file #.

--defaults-extra-file=# Read this file after the global files are read.

--defaults-group-suffix=#

Also read groups with concat(group, suffix)
