All of the configurations and settings in Linux are saved in text files. Even though you most often can edit configurations through the graphical interface, you may occasionally have to edit them by hand. Kate is the default Kubuntu text editor, which can be launched by clicking ->-> from the desktop menu system.
At times in this guide, Kate is run from the command line using kdesu, as most configuration files require root privileges to alter them. It is recommended that you also run kdesu from the command line when shown in this guide.
Se necessitar de utilizar um editor de texto a partir da linha de comandos, pode utilizar o nano, que é um editor de texto simples. Quando o executar da linha de comandos, use sempre o comando seguinte, que assegura que o editor não introduz quebras de linha:
nano -w
Para mais informação sobre como utilizar o nano, veja o guia no wiki.
There are also quite a few other terminal-based editors available in Kubuntu, popular ones include VIM and Emacs (the pros and cons of each are cause for much friendly debate within the Linux community). These are often more complex to use than nano, but are also more powerful.
