Change locale & language inside ssh terminal

First you can have an overview of the setting of the system you are working with typing:

$ locale

You will obtain a list of all the avaiable locale setting (language, currecy, date....):

LANG=de_DE.UTF-8
LC_CTYPE="de_DE.UTF-8"
LC_NUMERIC="de_DE.UTF-8"
LC_TIME="de_DE.UTF-8"
LC_COLLATE="de_DE.UTF-8"
LC_MONETARY="de_DE.UTF-8"
LC_MESSAGES="de_DE.UTF-8"
LC_PAPER="de_DE.UTF-8"
LC_NAME="de_DE.UTF-8"
LC_ADDRESS="de_DE.UTF-8"
LC_TELEPHONE="de_DE.UTF-8"
LC_MEASUREMENT="de_DE.UTF-8"
LC_IDENTIFICATION="de_DE.UTF-8"
LC_ALL=

At this point we can modify the language:

$ export LANG=en_UK.UTF-8

Obviously once you will have logged out you will lose all your setting.
