(The following is an idea I’ve been mulling over and talking to friends about for a few months. I thought I’d finally share it to see if anyone liked it or was interested in working on it.) Warning: Evo psych just-so story to follow. Think of it as a parable, not as a theory. It’s just here to contextualize the idea that follows. The Story
Environment variables provide a way to influence the behaviour of software on the system. For example, the "LANG" environment variable determines the language in which software programs communicate with the user. Environment variables consist of names that have values assigned to them. For example, on a typical system in the US we would have the value "en_US.UTF-8" assigned to the "LANG" variable. The meaning of an environment variable and the format of its value are determined by the application using it. There are quite a few well-known environment variables for which the meaning and the format have been agreed upon and they are used by many applications.
I just need a help to show me how to setup java path on Linux. How can I set JAVA_HOME and PATH variables for every user under my Linux system? ~/.bash_profile is a startup script which generally runs once. This particular file is used for commands which run when the normal user logs in. Common uses for .bash_profile are to set environment variables such as PATH, JAVA_HOME, to create aliases for shell commands, and to set the default permissions for newly created files. Set JAVA_HOME / PATH for a single user
After several trials and tribulations , I finally managed to get an independent Python 2.6.1 version running smoothly on Ubuntu 8.10 (“Intrepid”) , without interfering with the system’s reliance on Python 2.5 and without breaking the entire package dependency system. The procedure described here has been successfully carried out on the Easy Peasy distribution of Ubuntu (ex-”Ubuntu-eee”), specifically tailored for the Asus EEE-PC . It should work, though, with any other 8.10 version of Ubuntu. It has also been tested successfully on Ubuntu 8.04 (“Hardy”).
There are many reasons you might want to reset a password: Someone gave you a computer with Ubuntu installed on it but not the password for the user account. You just installed Ubuntu and forgot what password you selected during the installation process. You have too many passwords in your life and can't keep track of them all.
Linux Server Hardware Requirements The minimum specifications for your Linux server hardware depend on the role the server is going to play, what processes will run, how many users it will have and how you intend to configure it (from the command line or from the GUI). Generally speaking the hardware required for a Linux server is found at the lower end of the scale and often ordinary desktop PC components are more than sufficient. Be wary of the slick salesperson trying to sell you a 1RU rackmounted server with all the bells and whistles when all you require is a machine to run your web based customer management system to five users on the office network.
Linux From Scratch (LFS) is a project that provides you with step-by-step instructions for building your own customized Linux system entirely from source. Why would I want an LFS system? Many wonder why they should go through the hassle of building a Linux system from scratch when they could just download an existing Linux distribution. However, there are several benefits of building LFS.
