      @mysql -h host -D dbname -u user@

      I guess your can omit host parameter if you are connecting to localhost. You might need to specify "-p password" switch also (depends on mysql configuration).

        i think i did not install any mysql client. bcause it displays this output
        @
        root@zafar-laptop:/# mysql -h localhost -D testTwo -u root -p xxxxxx
        The program 'mysql' can be found in the following packages:

        • mysql-client-core-5.1
        • mysql-client-5.0
        • mysql-cluster-client-5.1
          Try: apt-get install <selected package>

          Run
          @dpkg --list | grep mysql@
          and post the output for this command.

              How did you create your database? I don't see any mysql server either.

                    Ok, I see. What is the location of your XAMPP installation? try to find the mysql binary there. And use the whole path (since I assume it is not in PATH) when connecting, i.e.

                    @/path/to/xampp/bin/mysql -D dbname -u username@

                    UPD: Didn't notice the location of xampp. then try (I guess it would be like this) @/opt/lampp/bin/mysql@

                        Try not passing -p switch. I guess you will be prompted to type in your password.
                        or
                        @/opt/lampp/bin/mysql -u root testTwo@

                            I'm sorry i just confused you with my last post.

                            @/opt/lampp/bin/mysql -u root -p 123456 testTwo@

                            I thought that mysql would prompt you but it didn't.

                              Do it this way, then it will prompt for a password:

                              @/opt/lampp/bin/mysql -D testTwo -h localhost -u root -p
                              @

                                  Cut it into pieces or use something like pastebin.

                                          Hm, apparently mysql is rather strict in terms of specifying parameters. Try to follow ¤ Dii ¤'s instructions.
