Since both jobs are very close to each other, its in most cases that the system engineers have been system administrators for a long while before they moved into engineering.

I still don't know if I want to do systems administration and then either stay with that or move up to systems engineering, or just go for systems engineering from the start Smilie

. They both look like fun jobs. What I was thinking of doing though is if I want to do systems administration I'd get a bachelors degree in computer science( and of course learn as much about unix as I can right now) and then when I know enough about unix try and get a position as a system administrator.
If I decided to become a systems engineer though, what my plan for that was was to get a masters of computer science and of course learn as much as I can about Unix, and then try and get a level I systems engineering job. From the information I was able to find there is level I, II, III, IV, and V engineers. Maybe it'd be better to start with Systems Administration though and if I feel like moving up to systems engineering I could? Do you by any chance know how long most people are systems administrators before they become systems engineers? I'm having a really hard time deciding which I want to do Smilie

I'm a bit concerned about my salary too because I'd like to be making enough to be able to get a nice house out in Colorado Springs. It looks like I need about at least $100k salary to do that though(hopefully the housing market will change though). Which is why I was planning on remaining here in PA and living in a townhouse for probably another 10 - 12 yrs years after I have my degree and have started working. The cost of living is really low here(at least, low for the way the economy is over here in the US) and I could probably save up a down payment for a house in CO while I'm living here. From what I figure though from what most people said, and according to SAGE(which someone here sent me the link to), most Systems Administrators make between $85k and $91k a year here in the US. According to salary.com software engineers(which I'm guessing a Unix Systems Engineer would count as a software engineer) make about $110k... not sure how accurate that is though. Anyways, pretty much what I want is a job that's Unix related that makes a pretty good salary(enough that I get a nice house) and is something I would enjoy doing. and like I said, both of those jobs looks like something I'd enjoy doing.
Thanks again for your help zxmaus!

Anyone who has any more info I'm still open to hearing all I can about these 2 jobs and what they're like Smilie

queuedefs

queuedefs(4)							   File Formats 						      queuedefs(4)

NAME

       queuedefs - queue description file for at, batch, and cron

SYNOPSIS

       /etc/cron.d/queuedefs

DESCRIPTION

       The queuedefs file describes the characteristics of the queues managed by cron(1M). Each non-comment line in this file describes one queue.
       The format of the lines are as follows:

	      q.[njobj][nicen][nwaitw]

       The fields in this line are:

       q	The name of the queue. a is the default queue for jobs started by at(1); b is the default queue for jobs  started  by  batch  (see
		at(1)); c is the default queue for jobs run from a crontab(1) file.

       njob	The  maximum  number of jobs that can be run simultaneously in that queue; if more than njob jobs are ready to run, only the first
		njob jobs will be run, and the others will be run as jobs that are currently running terminate.  The default value is  100.

       nice	The nice(1) value to give to all jobs in that queue that are not run with a user ID of super-user.  The default value is 2.

       nwait	The number of seconds to wait before rescheduling a job that was deferred because more than njob jobs were running in  that  job's
		queue, or because the system-wide limit of jobs executing has been reached.  The default value is 60.

       Lines beginning with # are comments, and are ignored.

EXAMPLES

       Example 1: A sample file.

       #
       #
       a.4j1n
       b.2j2n90w

       This  file  specifies that the a queue, for at jobs, can have up to 4 jobs running simultaneously; those jobs will be run with a nice value
       of 1.  As no nwait value was given, if a job cannot be run because too many other jobs are running cron will wait 60 seconds before  trying
       again to run it.

       The  b  queue, for batch(1) jobs, can have up to 2 jobs running simultaneously; those jobs will be run with a nice(1) value of 2.  If a job
       cannot be run because too many other jobs are running, cron(1M) will wait 90 seconds before trying again to run it. All	other  queues  can
       have up to 100 jobs running simultaneously; they will be run with a nice value of 2, and if a job cannot be run because too many other jobs
       are running cron will wait 60 seconds before trying again to run it.

FILES

       /etc/cron.d/queuedefs	       queue description file for  at, batch, and  cron.
