How to import database in mysql running on XAMP

Hey guys i know this question seems to funny that’s why i wanna clear it more.

I am running a local server on my ubuntu 12.04 on xamp.

Question: I have 30 database and wanna backup them in one step for that i’m using this:

# mysqldump -u root -p --all-databases > backu.sql  .

The syntax is working fine and now i have a full backup of my all database.

PROBLEM NOW I WANT TO IMPORT THEM AND SEE THEM AGAIN IN PHPMYADMIN using following command.

# mysql -u username -p < dump.sql

error: The program ‘mysql’ is currently not installed. You can install it by typing:

$ sudo apt-get install mysql-client-core-5.5

all know when you install xamp you dont need to install mysql separately.

May be try to view log file concerning XAMP, and if possible put the screen shot for us to view.
But if running:

$ sudo apt-get install mysql-client-core-5.5

helps then i suggest you try to do it.
