Linux administrators are a sub group of information technology jobs (IT). Linux is a specific operating system which handles most of the common tasks on servers which run the internet and internal corporate intranets. Because Linux is a free and open source operating environment, it has become very popular. Many different versions have been created by programmers who seek to tailor the operating system to different needs. This versions are call distributions or distros in computer lingo. There are, however, different versions of Linux which are sold commercially. Administrators usually install, prepare, evaluate, and maintain the different Linux distributions.
Linux administrator jobs are expected to grow significantly much faster than the average when compared to all other types of positions. It is projected that there will be more than 250,000 new jobs by 2018 according to The Bureau of Labor Statistics. Job prospects are expected to be excellent for Linux administrators. It's also important to note that computer skills have a higher importance than formal education.
Working ConditionsThe working environment for Linux administrators tends to be in well-lit, comfortable, and clean offices and computer labs. Most work a typical 40 hour work week. The percentage of administrators who work more than 50 hours a week is usually 15% or lower. Some administrators may be required to be on call due to their level of intimacy with the systems they maintain. Should there be system failures or other problems, the administrator would be the one capable of restoring it to proper functioning within the shortest time possible.
CompensationStarting salaries tend to be around $41,000 a year or more. The median income for all network administrators is just over $66,000. The top ten percent earn over $100,000 a year. The highest paying positions are in private companies. Lower paying positions are typically in elementary and secondary schools.
Qualifications and TrainingMost positions typically ask for at least a bachelor's degree. However, associate degrees or other professional certification may be adequate when combined with related work experience. It's possible to begin as a computer support specialist before advancing to administrator.
One common problem that is faced by Linux system administrators is not understanding permissions. Not backing up critical configuration files and not choosing good root passwords are other problems new Linux system administrators may face.

There is no "Linux 4" or "Linux 9." I'm not sure where people get these numbers from. They could be reading the version numbers of a particular distro (such as Red Hat Enterprise Linux 4 or SUSE Linux Enterprise Server 9). However, the Linux kernel is developed centrally and then subsequently used by all of the distribution vendors. The current stable version of the Linux kernel is 2.6.30; the 2.6 kernel line is expected to continue indefinitely.
The 'ls' command is the same in Linux and Unix systems. System Administrators may set up an alias that has the -FC or other options but the command itself with no other parameters (ls) is just the 'ls' command.
Answer Scarcity causes demand and demand establishes a market, ultimately the sales increase. I think that 'increase of sales' is the expected demand.
