Linux+ Guide to Certification for Linux
Use Gnu/Linux, hands On first. Wars are not being won with papers but by bloody battles one by one until you are in control of the enemy.
Your post is a poor title. Be specific in what is the problem to solve. We are not meant to respond to the yelling of a drowning picnic swimmer.
This site is for doers of gnu/linux not for hypocrite papers good for ***wipe.
Forgive my drastic response but I have allergy to hypocrisy. If indeed you know something about gnu/linux you will know how to use google or teoma.com.
