It is simple to set environment variables that affect your whole session. Plasma will execute any script it finds in $HOME/.config/plasma-workspace/env whose filename ends in .sh, and it will maintain all the environment variables set by them. It is important that any variable you want to set must be also exported. In the case of PATH, for instance, your system will be set up with certain likely directories as the likely places to find things. Now you are adding an extra possible search place. You can see what is already set by opening Konsole and typing echo $PATH
To add paths to your PATH, simply create a file named $HOME/.config/plasma-workspace/env/path.sh with a contents similar to this:
export PATH=$HOME/local/bin:$PATH
Розгляньмо наш приклад докладніше. Команда export повідомляє системи, що визначається щось, що має бути збережено і використано для пошуку файлів. Далі ви маєте вказати повністю шлях до каталогу, який слід додати (у нашому прикладі ~/local/bin, тобто /home/ви/local/bin, знову ж таки, ви можете скористатися командою echo $HOME, щоб переглянути шлях до каталогу повністю). Нарешті, вказано саму змінну $PATH, щоб вказати, що ви хочете додати до неї новий каталог, а не замінити список вже вказаних каталогів.
Часто цього достатньо. Але якщо ви продовжите вивчення системи, ймовірно, у вас вам захочеться мати те саме середовище під час користування консоллю або доступу до вашої системи за допомогою ssh, вам доведеться додати наприкінці вашого файла .bashrc щось таке:
source $HOME/.config/plasma-workspace/env/path.sh
You can also check how Plasma 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.
