Welcome Nataan03,

Experience is usually better than certification. Getting the first step in is the hardest, but you will also find that much of the certification is about experience rather than answering questions based on abstract ideas.

A bit like in a driving theory test or direct questions from the examiner, being asked:- Without experience, it is unlikely you will know the answer.

If you have a job, work hard at that job and try to push for more exposure from whomever is more senior on the project and/or access to the OS support team.

Depending on the OS being used, there will be a variety of courses and certifications to work through as your interest takes you. What OS are you using? We can probably best suggest something from that. The skills of each OS are usually very similar, although the tools on each may vary considerably. Everyone has their own preference, but in my experience there are generally four to consider:-The last one covers a multitude of variations (RedHat, Suse etc.) but they are far more similar to each other that the other three main players so a course in those should suit them all. The 'big three' are the main commercial players, but all in all the concepts are very similar.

Focus on the one that suits you best in your job (where you can practice) and translate between them using this site or a similar one (search on "unix rosetta"):-

Rosetta Stone for Unix

Remember that on each server, the relevant manual pages should be installed, so there is always documentation to guide you when you know the command to be using and the references at the end of each will give you related commands to explore too.


I hope that this helps,
