Basic Linux Command (Kill a print job)

I had a problem killing my print job seems that it got stock and the message annoys me,there is no icon for the printer and option to kill the job so here is what I did. There are two option:

Option A:

point your browser to http://localhost:631/jobs

Option B: (this is the option I choose)

run lpq -a from a terminal

it will show the jobs that are trying to run

Then

run lprm "jobid"


Since there are allot of jobids i made a simple script:

$for i in '54 56 58 59 60 61'; do lprm $i; done

The CentOS Adventure

You should not forget where you came from, I could relate this with my adventure with centos (CentOS is a freely-available operating system that is based on Red Hat Enterprise Linux. ) During my early years with linux I started with RedHat 7.2 till RedHat 9 then my previous company switch to mandrake actually its a customize drake we were installing from a harddisk to our server (I forgot doing that) I been setting up proxys, firewall and samba server with it.Next was debian I fall in-love with apt-get although yum was ok with me during those days but apt-get was an easy breez coz no dependencies was miss out by apt-get. Then Ubuntu came it was a haven OS for me. Now I'm setting up a LTSP out of Centos,why? Audio issue unsloved. So I would like to try it in RedHat environment. I said to my self this is just old times but when I was configuring it I'm using debian commands and paths, although linux commands and paths are universal there are still some would be different like for example network config in ubuntu I go to /etc/network/interfaces to edit my network interface card while in centos its under /etc/sysconfig/network-scripts/ifcfg-eth*. Also if I want to know what release I'm using I typed lsb_release -a, this command wont work with centos. My adventure is not yet over I will still be diving or lets says visiting with my old roots of linux.
