I want to install the MySQL client for the command line, not a GUI. I have searched over the web but only found instructions on installing the MySQL server.
If you have already installed MySQL from the disk image (dmg) from http://dev.mysql.com/downloads/), open a terminal, run:
echo 'export PATH=/usr/local/mysql/bin:$PATH' >> ~/.bash_profile
then, reload .bash_profile by running following command:
. ~/.bash_profile
You can now use mysql to connect to any mysql server:
mysql -h xxx.xxx.xxx.xxx -u username -p
