Geeky Fun: Kolab2

I’ve been setting up Kolab over the past few days. I’ll report in when I have something interesting to say, but for now let’s just call it an “interesting” experience :)

HOW TO: Prepare a Partition to be Swap

If you’re about to install a Linux distro, then the install program will likely take care of this for you. If you’ve changed file systems under other circumstances, however, you may need to manually prepare a partition to be used as swap.
The command to do so is simply mkswap as in:
mkswap /dev/hda2
Mkswap will not […]

HOW TO: Find Out What Partition I Am On

I’ve been reading up on the df command. The df command shows free disk space and I’ve covered it before. It has one function that I didn’t know about, however, and that’s the ability to show you which disk and partition you are on at any given time.
The command
df . (see the dot?)
will return the […]

HOWTO: Make a Filesystem

So you’ve used fdisk or cfdisk to create some partitions on your disk. Great, now what? Well, to be able to use your new partitions, you’ll need to put a file system on them. If your plan is to install an operating system on your new partitions then it’s likely that the OS install application […]

Explanation: Fdisk and Cfdisk Disk Partitioners.

There are two broad types of disk partitioning: destructive and non-destructive.  This blog entry deals with destructive partitioners. I would have preferred to make a HOW TO out of this entry but I don’t have a dev system that I can wipe right now, so I’m just going to take a look at fdisk and […]

Explain: What Directories Must be on My / Mount Point?

Given that the / (or root) mount point is the first (only?) file system mounted at boot time, it must contain certain directories and files so that the system can boot. The directories that must reside on / are:
/bin
/sbin
Both contain binary programs for users (bin) and superuser (sbin)
/dev
Contains device files such as hard drive and […]

Comments And Spammers

On an administrative note - until further notice, I will not be moderating any comments for New Linux User. Quite simply, the spammers have won and I am now presented with over 200 spam comments each morning when I log on to NLU. Sadly, I do not have the time to sort through 200+ comments […]

HOWTO: Use the Grep Command

One of the problems with writing an entry on the grep command is that it’s so invloved. Grep is a “take it or leave it” command. By that I mean that it can be used easily and quickly with few options, or it can be used with jedi-like mastery. You can basically get as involved […]

Geeky Fun: The Origins of GREP

This is pretty much taken verbatim from my LPI Linux Certification in a Nutshell book:
The word grep is actually an acronym. The line editor ed contained (contains?) a command to display the lines of a file being edited that matched a pattern. The command was:
g/regular expression/p
In essence this mean ‘global regular expression print’. The concept […]

HOWTO: Change a Running Processes’ Priority with Renice

You can change the default priority that an application runs with by starting it with the nice command, but if you want to change the priority of a process that is already running, the command to use is renice.
Renice can be used to change the priority of a single process, or of all the processes […]
