Path to Linux / Unix Systems Administrator

Hello!

I have seen similar questions asked about how to become a system administrator. Most would say experience is more important than just getting a certificate and even a degree. However, I haven't found a good information how to build experience from a newbie to entry-level systems administrator. Do you have a recommendation of books, websites, articles and learning materials that would guide a newbie toward path to linux / unix systems administrator?

I have read FreeBSD handbook and used FreeBSD as my first "unix" experience. Then I switched to Ubuntu for my main home desktop usage. I am starting to look into OpenSolaris and Solaris docs (Solaris 10 System Administration Collection at docs.sun.com). I am even tempted to attempt to study RHCE exam but wondering if it will help me gain experience (not just to earn the certificate itself). I guess I am wandering aimlessly not sure what steps to take. However, I know I fell in love with unix / bsd / linux. :-)

Any advice would be greatly appreciated!

EXICYCLOG(8)						      System Manager's Manual						      EXICYCLOG(8)

NAME

       exicyclog - Cycle exim's logfiles

SYNOPSIS

       eximcyclog

DESCRIPTION

       The  exicyclog script can be used to cycle (rotate) mainlog and rejectlog files.  This is not necessary if only syslog is being used.  Some
       operating systems have their own standard mechanisms for log cycling, and these can be used instead of exicyclog if preferred.

       Each time exicyclog is run the file names get 'shuffled down' by one.  If the main log file name is mainlog (the default) then when  exicy-
       clog is run mainlog becomes mainlog.01, the previous mainlog.01 becomes mainlog.02 and so on, up to a limit which is set in the script, and
       which defaults to 10.  Reject logs are handled similarly.

       If no mainlog file exists, the script does nothing.  Files that 'drop off' the end are deleted.	All files with numbers greater than 01 are
       compressed,  using a compression command which is configured by the COMPRESS_COMMAND setting in Local/Makefile.	It is usual to run "exicy-
       clog" daily from a root "crontab" entry of the form

	 1 0 * * * su exim -c /usr/exim/bin/exicyclog

       assuming you have used the name 'exim' for the Exim user.  You can run exicyclog as root if you wish, but there is no need.

BUGS

       This manual page needs a major re-work. If somebody knows better groff than us and has more experience in writing manual pages, any patches
       would be greatly appreciated.
