DESCRIPTION
       Dumping definition and data mysql database or table mysqldump supports by executing

       -A|--all-databases
	      Dump all the databases. This  will  be  same  as	--databases  with  all	databases
	      selected.

       -a|--all
	      Include all MySQL specific create options.

       -#|--debug=...
	      Output debug log. Often this is 'd:t:o,filename`.

       --character-sets-dir=...
	      Directory where character sets are

       -?|--help
	      Display this help message and exit.

       -B|--databases
	      To dump several databases. Note the difference in usage; In this case no tables are
	      given. All name arguments are regarded as databasenames.

       -c|--complete-insert
	      Use complete insert statements.

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

       --default-character-set=...
	      Set the default character set

       -e|--extended-insert
	      Allows utilization of the new, much faster INSERT syntax.

       --add-drop-table
	      Add a 'drop table' before each create.

       --add-locks
	      Add locks around insert statements.

       --allow-keywords
	      Allow creation of column names that are keywords.

       --delayed-insert
	      Insert rows with INSERT DELAYED.

       -F|--flush-logs
	      Flush logs file in server before starting dump.

       -f|--force
	      Continue even if we get an sql-error.

       -h|--host=...
	      Connect to host.

       -l|--lock-tables
	      Lock all tables for read.

       -n|--no-create-db
	      will not be put in the output. The above line will be added otherwise,  if  --data-
	      bases or --all-databases option was given.

       -t|--no-create-info
	      Don't write table creation info.

       -d|--no-data
	      No row information.

       -O|--set-variable var=option
	      give a variable a value.	--help lists variables

       --opt  Same as  --add-drop-table --add-locks --all --extended-insert --quick --lock-tables

       -p|--password[=...]
	      Password to use when connecting to server.  If password is not given it's solicited
	      on the tty.

       -P|--port=...
	      Port number to use for connection.

       -q|--quick
	      Don't buffer query, dump directly to stdout.

       -Q|--quote-names
	      Quote table and column names with `

       -S|--socket=...
	      Socket file to use for connection.

       --tables
	      Overrides option --databases(-B).

       -T|--tab=...
	      Creates tab separated textfile for each table to given path. (creates .sql and .txt
	      files).	NOTE:  This  only  works  if  mysqldump is run on the same machine as the
	      mysqld daemon.

       -u|--user=#
	      User for login if not current user.

       -v|--verbose
	      Print info about the various stages.

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

       -w|--where=
	      dump only selected records; QUOTES mandatory!

       --delayed
	      Insert rows with the INSERT DELAYED command.

       -e|--extended-insert
	      Use the new multiline INSERT syntax. (Gives more compact and faster inserts  state-
	      ments.)

       --fields-terminated-by=...

       --fields-enclosed-by=...

       --fields-optionally-enclosed-by=...

       --fields-escaped-by=...

       --lines-terminated-by=...
	      These  options  are used with the -T option and have the same meaning as the corre-
	      sponding clauses for LOAD DATA INFILE. See Mysql	manual	section  7.23  LOAD  DATA
	      INFILE Syntax.

       -v|--verbose
	      Verbose mode. Print out more information on what the program does.

       -V|--version
	      Print version information and exit.

       -O net_buffer_length=#, where # < 16M
	      When  creating  multi-row-insert	statements  (as  with option --extended-insert or
	      --opt ), mysqldump will create rows up to net_buffer_length length. If you increase
	      this  variable,  you should also ensure that the max_allowed_packet variable in the
	      MySQL server is bigger than the net_buffer_length.

EXAMPLES
       The most normal use of mysqldump is probably for making a backup of whole  databases.  See
       Mysql Manual section 21.2 Database Backups.

       mysqldump  --opt database > backup-file.sql

       You can read this back into MySQL with:

       mysql  database < backup-file.sql

       or

       mysql  -e 'source /patch-to-backup/backup-file.sql' database

       However,  it's  also  very useful to populate another MySQL server with information from a
       database:

       mysqldump --opt database | mysql --host=remote-host -C database

       It is possible to dump several databases with one command:

       mysqldump --databases database1 [ database2 database3... ]  > my_databases.sql

       If all the databases are wanted, one can use:

       mysqldump --all-databases > all_databases.sql
