Databese convertion

I have a batabase made with mysql running on windows NT , but I have to use it on mysql on linux is there any ways to convert the database

No need to *convert* it. Just use mysqldump to export all SQL commands used to build the database (you can also include all record inserts).

mysqldump -u [user] -p [database] > filename.sql

pipes the output to a text file, which you can then use to create the identical database on your Linux machine.
