MySQL dump from command line

You can accomplish this using the mysqldump command-line function.

For example:

If it’s an entire DB, then:

   $ mysqldump -u [uname] -p[pass] db_name > db_backup.sql

If it’s all DBs, then:

   $ mysqldump -u [uname] -p[pass] --all-databases > all_db_backup.sql

If it’s specific tables within a DB, then:

   $ mysqldump -u [uname] -p[pass] db_name table1 table2 > table_backup.sql

You can even go as far as auto-compressing the output using gzip (if your DB is very big):

   $ mysqldump -u [uname] -p[pass] db_name | gzip > db_backup.sql.gz

If you want to do this remotely and you have the access to the server in question, then the following would work (presuming the MySQL server is on port 3306):

   $ mysqldump -P 3306 -h [ip_address] -u [uname] -p[pass] db_name > db_backup.sql

It should drop the .sql file in the folder you run the command-line from.
