Yes, UNIX is versatile. Typically if you say career in Unix, I would assume you want to be a Unix Administrator. Being a System Administrator myself, I would say it is very challenging and satisfactory job one could have as a techie. But current market is focusing on Cloud, more than JUST Unix Administrator, you need to focus more on Cloud based solutions as like , Dev-Ops Admin and focus on technologies like AWS (Amazon Web Services) and OES (Oracle Engineered Systems). Unix again has lot more sub parts and the famous ones are Solaris, AIX, HP-UX and Linux. And don't even ask about Linux, it has enormous flavors..
Unix administrator is responsible for installations, security and much other work to monitor servers of an organization. We should not consider their scope in the following areas mentioned.
-
- Cookie cutting software engineers.
- Developing any program.
- Designing of new software.
Unix administrator’s scope is related to the maintenance of existing software designed for the organization so that u are able to reply to it. With this, they must be able to understand the working of the software and the server to troubleshoot in case any technical issue related to software pr hardware occurs. One must have good hand in scripting languages such as Python, Perl, awk, shell, etc. to automate the work done in routine tasks. While entering as a fresher, one must concentrate on learning various IT skills in all areas including the leading IT technologies such as Cloud, IOT, etc.
“Unix Course” that is being offered in the “Market” covers only Unix Administration part. This will help you in getting an Admin kind of job like System Admin, Unix Admin. This won’t help in getting a Programming Job because it is over-skilled for that..
We are happy and proud to say that we have strong relationship with over 700+ small, mid-sized and MNCs. Many of these companies have openings for Unix Administrator analyst. Moreover, we have a very active placement cell that provides 100% placement assistance to our students. The cell also contributes by training students in mock interviews and discussions even after the course completion.
Having UNIX experience allows you to easily go into the Storage area. In fact most of the storage technologies are based on UNIX developments, so for learning purposes i rather use EMC2 and IBM SAN Volume Controller. You can also download and start with the FreeNAS software.Learning Linux does not need to much investment of money). Having some knowledge of AIX would be nice too but you need a customer with such environment.
You can take this course without any prior IT experience or certifications..
Yes, It's possible to become a virtuoso shell programmer without any previous programming experience. ... Several UNIX utilities and administration features depend on it
Our courseware is designed to give a hands-on approach to the students in Unix Administrator. The course is made up of theoretical classes that teach the basics of each module followed by high-intensity practical sessions reflecting the current challenges and needs of the industry that will demand the students’ time and commitment.
If you are a sysadmin then UNIX is certainly worth learning. ... If you mean is it worth learning to use of the command line on a Unix-like system, if you're going to manage a Unix-based server or servers then definitely Yes. You'll need to learn the file system commands and the core utilities too.
Well, that really depends. To become system administrator on basic level, you just need to learn how to install a computer and do basic troubleshooting and this you can learn in a week to a month
The top reason for the popularity of Unix Shell Scripting is its robust scope. It is a powerful programming method that can help you learn the command-line better, save time, and do away with tedious file management tasks.
Advantages of Unix Admin
The Unix operating system is one of computing's most significant technologies, providing the framework that the familiar Linux and Mac OS X operating systems were developed on. Unix can be a viable alternative to Windows-based computers in some cases, offering a stable and secure platform for hosting or other business applications. However, the system does not have the vast user base that the various forms of Windows do. An additional gripe is that novice users may find its command-driven interface confusing.
What Unix can Do?
- For servers which are not acceptable for any chances of downtime can be updated inactive state without pulling them into a reboot process.
- For real thin clients, it allows the overall operating system being rebooted from the network.
- Allows multiple hosts to be logged in multiple times by multiple people concurrently.
Advantages
- Allows multitasking with protected memory, so this allows concurrent users to run multiple programs at a parallel time without any system crash.
- A large number of programs can be easily executed with a self-effacing amount of memory. This clearly shows the amount of efficiency exhibited by the memory systems of Unix.
- Each and every user attempting to log in on to UNIX systems needs to be authenticated with a valid password and account.
- A large set of commands allows doing specific tasks well.
- The largely portable operating system which can be used across a large variety of systems
- Very much optimized program development environment.
- The following are the advantages of Unix Features.
Portability:
The system is written in high-level language making it easier to read, understand, change and, therefore move to other machines. The code can be changed and complied on a new machine. Customers can then choose from a wide variety of hardware vendors without being locked in with a particular vendor.
Machine-independence:
The System hides the machine architecture from the user, making it easier to write applications that can run on micros, mins and mainframes.
Multi-Tasking:
Unix is a powerful multi-tasking operating system; it means when a active task in in process, there can be a simultaneous background process working too. Unix handles these active and background threads efficiently and manages the system resources in a fair-share manner.
Multi-User Operations:
UNIX is a multi-user system designed to support a group of users simultaneously. The system allows for the sharing of processing power and peripheral resources, white at the same time providing excellent security features.
Hierarchical File System:
UNIX uses a hierarchile file structure to store information. This structure has the maximum flexibility in grouping information in a way that reflects its natural state. It allows for easy maintenance and efficient implementation.
UNIX shell:
UNIX has a simple user interface called the shell that has the power to provide the services that the user wants. It protects the user from having to know the intricate hardware details.
Pipes and Filters: UNIX has facilities called Pipes and Filters which permit the user to create complex programs from simple programs.
Utilities:
UNIX has over 200 utility programs for various functions. New utilities can be built effortlessly by combining existing utilities.
Performance
Unix is designed to maximize performance through economical memory use. The operating system uses protected memory -- a memory allocation system whereby a given block of memory can only be accessed by one application at a time -- to enable full multitasking, allowing multiple users to run multiple applications without risking a system crash. In addition, Unix applications generally require a fairly small amount of physical memory to run, thanks to the operating system's efficient use of virtual memory. Unix's virtual memory capabilities allow the operating system to use part of a computer's storage space as working memory, temporarily increasing available system resources and allowing large numbers of applications to run concurrently without experiencing a slowdown.
Security
Unix enforces high security levels by requiring that all users authenticate to the system via a username and password. Furthermore, all files on the system must have an owner, who can set specific permissions as to which users can or cannot read or modify that file. This security system reduces the possibility that an unauthorized user could gain access or tamper with important files or documents on a Unix system.
Complexity
Perhaps the primary disadvantage of Unix is the steep learning curve associated with using the software. Using the operating system to its full potential requires learning the Unix shell commands -- a vast set of text-based system commands that vaguely resemble the commands used in Microsoft's DOS operating system. Learning these commands can take far longer than it it takes to use the graphical interface on an operating system such as Mac OS X or Windows.
Assistance
Getting help with a Unix application or process can be more difficult than in a Windows environment. Unix documentation can be long-winded, difficult to read or even non-existent, and the system's relatively small user base decreases your chances of finding someone who can help you with your problem. By contrast, new Windows releases virtually always ship with comprehensive and user-friendly documentation.
