mysqldump
mysqldump http://dev.mysql.com/doc/refman/5.5/en/mysqldump.html
A client that dumps a MySQL database into a file as SQL, text, or XML.
The mysqldump client is a utility that performs logical backups, producing a set of SQL statements that can be run to reproduce the original schema objects, table data, or both. It dumps one or more MySQL database for backup or transfer to another SQL server. The mysqldump command can also generate output in CSV, other delimited text, or XML format.
Syntax There are in general three ways to use mysqldump—in order to dump a set of one or more tables, a set of one or more complete databases, or an entire MySQL server—as shown here: shell> mysqldump [options] db_name [tbl_name ...] shell> mysqldump [options] --databases db_name ... shell> mysqldump [options] --all-databases
To dump entire databases, do not name any tables following db_name, or use the --databases or --all-databases option.
mysqldump does not dump the INFORMATION_SCHEMA database by default. mysqldump dumps INFORMATION_SCHEMA only if you name it explicitly on the command line, although currently you must also use the --skip-lock-tables option. Before MySQL 5.5 mysqldump silently ignores INFORMATION_SCHEMA even if you name it explicitly on the command line.
mysqldump does not dump the performance_schema database.
Before MySQL 5.5.25, mysqldump does not dump the general_log or slow_query_log tables for dumps of the mysql database. As of 5.5.25, the dump includes statements to recreate those tables so that they are not missing after reloading the dump file. Log table contents are not dumped.
mysqldump also does not dump the MySQL Cluster ndbinfo information database.
To see a list of the options your version of mysqldump supports, execute mysqldump --help.

Mysql programs
All these try PROGNAME --help for details
also http://dev.mysql.com/doc/refman/5.5/en/programs-overview.html
The MySQL server, mysqld, is the main program that does most of the work in a MySQL installation. The server is accompanied by several related scripts that assist you in starting and stopping the server:
mysqld
The SQL daemon (that is, the MySQL server). To use client programs, mysqld must be running, because clients gain access to databases by connecting to the server. See Section 4.3.1, “mysqld — The MySQL Server”.
mysqld_safe
A server startup script. mysqld_safe attempts to start mysqld. See Section 4.3.2, “mysqld_safe — MySQL Server Startup Script”.
mysql.server
A server startup script. This script is used on systems that use System V-style run directories containing scripts that start system services for particular run levels. It invokes mysqld_safe to start the MySQL server. See Section 4.3.3, “mysql.server — MySQL Server Startup Script”.
mysqld_multi
A server startup script that can start or stop multiple servers installed on the system. See Section 4.3.4, “mysqld_multi — Manage Multiple MySQL Servers”.
Several programs perform setup operations during MySQL installation or upgrading:
comp_err
This program is used during the MySQL build/installation process. It compiles error message files from the error source files. See Section 4.4.1, “comp_err — Compile MySQL Error Message File”.
mysql_install_db
This script creates the MySQL database and initializes the grant tables with default privileges. It is usually executed only once, when first installing MySQL on a system. See Section 4.4.3, “mysql_install_db — Initialize MySQL Data Directory”, Section 2.10.1, “Postinstallation Procedures for Unix-like Systems”, and Section 4.4.3, “mysql_install_db — Initialize MySQL Data Directory”.

See Section 4.5.2, “mysqladmin — Client for Administering a MySQL Server”.
mysqlcheck
A table-maintenance client that checks, repairs, analyzes, and optimizes tables. See Section 4.5.3, “mysqlcheck — A Table Maintenance Program”.
mysqldump
A client that dumps a MySQL database into a file as SQL, text, or XML. See Section 4.5.4, “mysqldump — A Database Backup Program”.
mysqlimport
A client that imports text files into their respective tables using LOAD DATA INFILE. See Section 4.5.5, “mysqlimport — A Data Import Program”.
mysqlshow
A client that displays information about databases, tables, columns, and indexes. See Section 4.5.6, “mysqlshow — Display Database, Table, and Column Information”.
mysqlslap
A client that is designed to emulate client load for a MySQL server and report the timing of each stage. It works as if multiple clients are accessing the server. See Section 4.5.7, “mysqlslap — Load Emulation Client”.

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

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.
(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.
