can anyone please tell me how would I become linux certified, and in which distro should I become certified.
would you guys please tell me any book that I can use to help me study for the certification.
I just don't know which certification will be a better choice for the future.
I use mandrake and redhat as my distro.

You have a lot of questions and there is no easy answer. The only cert that I know of that is distribution specific is the RHCE for Red Hat. For distro neutral certification I think that the LPI is more industry recognized.

If there are companies you want to work for that only use Red Hat only then get an RHCE. If not then the LPI would be a better choice.

As far as paper books, I like LPI Linux Certification in a Nutshell by Oreilly. Still cant' compare to the LPI tutorials on IBM developerWorks. Look on the link I posted above.

Well there is the Suse Certs --> http://www.suse.com/us/business/serv...ion/index.html

There is a thread already in this forum that talks about the Linux Certs available -->> http://linuxquestions.org/questions/...hreadid=161390

I agree that going the neutral route is the better option unless you are working for or planning to work for a company that uses Red Hat or Suse specifically.
