This subchapter looks at init, a Linux command.
init is used to change the runlevel.
Linux has run levels (sometimes written as a single word, runlevel). The non-graphic mode is run level 3. the graphic mode is run level 5. Sometimes a Linux server will only boot up to the non-graphic level. You can use this command to temporarily get the graphic interface running (run level 5).
$ init 5
Edit the /etc/inittab file to include id:5:initdefault: to make a permanent change.
A chart of the Linux run levels:
| RUN LEVEL | DESCRIPTION |
|---|---|
| 0 | System is halted |
| 1 | Single-user Mode used for system maintenance |
| 2 | Multiuser mode withut networking rarely used |
| 3 | Standard multiuser mode with networking active |
| 4 | not defined |
| 5 | Multiuser mode with graphics Like standard multiuser mode with networking active plus the X Window System graphic interface |
| 6 | Reboots the system shuts down all system services |
Coding example: I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).

Work on this project is very slow because I am homeless. I am available for work if someone can provide an indoor place to work in Costa Mesa, California, electricity, internet connections, a flat raised working surface (such as a table or desk), a sitting device (such as a chair or stool), and a fully functional reasonably modern used computer. I’m already homeless, so you don’t need to pay me (and I understand how much business people hate the minimum wage law). Just give me a chance to work.

free book on UNIX/Linux System AdministrationTeach Yourself UNIX/Linux System Administration and Shell Programming free computer programming text book projectBuilding a free downloadable text book on computer programming for university, college, community college, and high school classes in computer programming. If you like the idea of this project, At the time I am homeless. This greatly interferes with my ability to create this project, which can help nearly 20 million U.S. college students and more than 150 million students world-wide. I am looking for 30 rich people or corporations willing to donate $10 a month to my church so that the church can provide a place indoors for me to continue work.
