Ubuntu, the incredibly versatile operating system based on Debian GNU/Linux is the most used linux system used nowadays. It is pretty standardized that ubuntu makes two new releases every year with the latest one being Ubuntu 9.04 (Jaunty Jackalope). I thought it would be nice to make a small overview and see what have the ubuntu releases been since today.
If you are a Linux/Unix user, chances are that you are using the well known vim editor for your casual text editing. In case you are not familiar with it, Vim is a text editor that has no GUI and is executed via the unix shell. You may be thinking that this makes it more difficult to use, but once you get to know the basics, you will begin to love the idea that you don’t have to use your mouse to change lines and will also be surprised at its efficiency.
Sudo, is a program that allows a system user to execute commands like he/she was the administrator of the system. By default, the only user of the system that is allowed to use sudo, is the root user, also called superuser. However, there is the file /etc/sudoers inside which we can add the users of the system that we allow them to use sudo.
Subversion is a software version management tool.Practically, this means that if we make project that contains code, we have always the stress that we do something error and we cannot restore previous versions of that code.Moreover, if a lot of individuals working with the same code (they write it at the same time), what will become if they edit a file or code in the same time but in a different way ? A solution would be that one phones the other and says to him what changes he had made, but this seems a bit unpractical, don’t you think? This process is what the versioning control software does, it informs us if something that we need to change has already been edited and keeps versions of the changes that have undergone by the various developers of the project.
Hello friends, at this next tutorial i’m writing for codercaste.com i’ll be trying to explain some things about the unix commands. I happen to be a linux user mainly and i find that the command shell of the various linux distribution is definately the raw power of linux.
