Definir les variables d'entorn de la sessió

Configurar les variables d'entorn que afecten a tota la sessió és fàcil. El KDE executa qualsevol script que troba a $HOME/.kde/env si el nom acaba en .sh, i mantindrà totes les variables d'entorn establertes per aquests. És important que qualsevol altra variable que vulgueu establir també sigui exported. En el cas de PATH, per exemple, el sistema es configurarà amb certs directoris on probablement siguin els llocs on trobar les coses. Ara afegireu un lloc addicional de cerca. Podeu veure el que ja està establert obrint Konsole i escrivint echo $PATH

Per afegir rutes a la vostra (computing) PATH, només cal crear un fitxer anomenat $HOME/.kde/env/path.sh amb un contingut similar a aquest:

export PATH=$HOME/local/bin:$PATH

Let's explore that. The command export tells the system that this is something that should be saved and used when looking for files. Next you add the full name of the directory you want to add (in this case ~/local/bin, another way of writing /home/you/local/bin - again you can use echo $HOME to see how that works). Finally you see the $PATH variable itself - that's because you want to add your new path into it, not replace the existing path.

Often that will work well enough for you, but as you get more familiar with the system you will probably want to have the same environment when using a console or accessing your machine via ssh, you will need to add to the end of your .bashrc something like this:

source $HOME/.kde/env/path.sh

You can also check how KDE actually does it. It's done in your local startkde, which normally you can find in /usr/bin/startkde. If you are interested in reading the code, you can can view it online. Just search the file for environment variables.
