uname -a output

) This particular distribution seems to be Red Hat Enterprise Linux 5 (.el5 in the output of uname -a). As for the books, there are plenty of various books taking the subject of Linux administration. I would suggest first going for some basic book covering Linux fundamentals, like managing files, working with the shell etc. After that you can move to something more specific, maybe something about administering RHEL5, so you can practice on your server. It is important to know that Linux comes in many different distributions, so books covering one might be not very accurate for another.|
