How do I use man? For example, when I enter:
I get a blank screen with a weird message at the bottom of the screen—something like 1/1. Whatever I enter, it beeps at me. —Josh Gray Slackware 3.2
Check whether there are any files in the /usr/man/manx directory (where x is a number, usually from 1 to 8). You should find several different files with names like gpm.1. Each of these files is a man page. Whenever you use the man command, you get a processed version of the file corresponding to the command specified (for the ls command, it is the ls.x file). For this file to be processed, the groff utility must be installed. groff is usually found in the /usr/bin directory. —Mario de Mello Bittencourt Neto, WebSlave email@example.com
When I installed Linux, I didn't set up a swap space. I have since created a swap file but I have to enter:
every time I boot, and I can do it only as root. Can I make this simpler? —Josh Gray Slackware 3.2
Slackware puts entries to automatically mount swap partitions (if they exist) in your rc script files. All you need to do is tell those files that your swap partition exists and is available for use. To do that, put a line in the /etc/fstab file like the following:
/dev/hda5 swap swap defaults 1 1
This tells the system to set up a swap space from /dev/hda5 with the default settings for a swap partition. This entry is normally created by the setup scripts when you install Slackware, and is the missing item that prevents your swap area from being initialized with each boot. —Chad Robinson, BRT Technical Services Corporation firstname.lastname@example.org
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
