Hi All, Can you please tell me if there is a recognised Certification for Unix/Linux? I know Brainbench does this, but now, I guess, it is not free. Could any of you tell me of any recognised certification for linux/unix(a free one)? Thanks & Regds, Aparna
i do not know of a free one... but Red Hat has several different certifications for Linux. They are expensive, though. i guess they do not want just "anyone" to get a certification... it helps to make sure that the people who do get certified are actually serious about their qualifications.
I dont know of *any* recognised (by who do you want to be recognised anyway?) certifications that are free. Administering a test properly costs -- so any completely free certification is unlikely to be valuable. IBM sometimes offer free exams under some conditions (or do you pass we pay for business partners). To be "recognised" you need either a professional body BCS for example or a vendor Sun/IBM/Red Hat -- I have seen the list of clients that Brainbech have, but seriously, would you rather be a Sun certified Solaris administrator, or Brainbench certified Solaris administrator. I expect that companies use Brainbench tests essentially as interview aids (exam conditions administered at the time) I have grave doubts about acceptence otherwise -- like the learning tree or Pitman certificates that people have -- essentially worthless. If you want a certificate, do it properly, any decent employer will cover the cost anyway. James
Most famous what? RedHat is (in the English speaking world) probably the best known Linux variant (Suse I believe is big in Continental Europe). It all depends what you want -- it is most sensible to get certified in whatever you know or do. If you are an AIX administrator, it is probably not wise to do Solaris or RedHat certification because it is better known, you should get AIX certified (first at least). If you dont know or use UNIX then you should question you motivation -- you can get Linux (many flavours) or Solaris for Intel free, so install one, get a book, study it and sit the exam. If you want to know which UNIX to learn, then the answer is simple: learn the Korn shell, learn vi, and the rest will follow
Red Hat is the most famous, and one of the most difficult for Linux. It involves an expensive hands on test. Linux+ and GNU Linux Certified Professional are the easiest. There is also Linux Professional Institute Certified. GNU Linux Certified Administrator involves 4 exams and is fairly difficult. LPIC and GNU also have just come out with higher level exams. Solaris Cerified Network Administrator is common, due to the popularity of Solaris. There are also HP-UX AIX, SCO, and SGI certifications. Sun has a higher network administrator certification. IBM has several additional cerifications.
