 |

mysqldump command dumps databases/tables to standart output. You can use pipe redirect to save it to file:
| Code: | | mysqldump [options] >dump.sql |
When you dump a database there are some options of mysqladmin you need to understand:
--skip-comments - Use this option if you want make a smaller file
--compatible - if you export database from higher version to lower you will need this option. Possible values are:--compatible=mysql323
--compatible=mysql40
--compatible=mysql323
--disable-keys - this will speed up import process
--add-drop-table - if you make backups you can assume that when you restore it, tables will be created and they need to be dropped. This option does it.
--quote-names - if you use reserved words as comumn or table names this will prevent errors during import.
