      Not having spent much time in the Linux / Unix command line in more than 20 years,.. I've lost all of that knowledge and with having a C@C account, find that I really need that knowledge again to really be able to use C@C. I'm not looking do do programing / coding but basic points of use.

      There is a lot of potential for the C@C service and the builds I have on a desktop and laptop here in the office. But past the GUI, I'm out of my element.

        They way I learn Linux was just by building shell only machines years ago and learned as I needed to do stuff. Google should help if you need it,

          Which Linux OS are you installing? Ubuntu and Debian are similar. CentOS 6 to CentOS 7 was a big leap in how things are done.

            I assume that you are good with the common ls, cd, ssh, pwd, mv and similar navigational commands?

                      Which CentOS? Version matters a bit.

                        First thing to do with any CentOS...

                        yum -y install epel-release

                          In CentOS you have YUM to make things easy. To install any software you just use...

                          yum install softwarename

                            And to fully update your system just run....

                            yum update

                              Be sure to install sysstat (System Stats) and htop (Horizontal TOP? Honestly, no idea what it stands for.)

                              yum -y install sysstat htop

                                Once you have sysstat installed and it has sat around for ten minutes or more you will start to get details in your sar reports. This is one of the most important tools in your Linux arsenal. Once it has sat around you can see all kinds of details as to how it has been running....

                                sar

                                  From http://hisham.hm/htop/index.php?page=faq:

                                  What does the 'h' in 'htop' stand for?

                                  Well, the short explanation is a little obvious: the "h" stands for "Hisham", my name. 🙂

                                  The long explanation is that what inspired me to write htop was pinfo, an improved man and info reader that adds lots of features (in my machines 'man' is an alias to 'pinfo -m'). It was written by a guy called Przemek Borys. Since 'pinfo' was "a better info" and he named it "pinfo" ("Przemek's Info"), I decided to try to make "a better top" so I called it "htop" ("Hisham's top"). So yes, it is after my own name, but it's also a homage to another nice piece of software!

                                    And of course the uptime command is super handy.

                                    -bash-4.2$ uptime
                                     14:39:39 up 6 days, 16:17,  1 user,  load average: 0.27, 0.16, 0.15

                                      So one of the goals is to have ManageEngine running. I've uploaded the .bin file, WHile I know I didn't need to.. it's done..

                                      would it be

                                      yum - y install (filename)?

                                        While I think YUM has a local installation option, I don't think it will work with bin files.

                                          A bin is a binary, like a Windows installer. It's not an RPM, which is an installation file. To install a binary, on any OS, just run it.

                                            Not sure why that quoted three time...

                                            I feel I hear Foghorn Leghorn's voice here... "No no no son,.. your don't it all wrong..."
