Partitioning for Kubuntu

[Qqmike]

@elijathegold: Ha! You're right: on this subject hard to tell who's right, and what "right" means. Well, anyway, I thought your summary of the principles and rules of thumb were pretty good.

[elijathegold]

The only thing WE did was to make the swap partition a bit on the heavy side at 8 GB, unless you meet the criteria elijathegold posted or you end up needing it.

It doesn't matter too much and better to err on the large side. I remember using the old 2x rule but that was back in the day when 1 and especially 2 GB was a good amount of ram which does make me feel old! Now-a-days everyone has an opinion on how much swap and those numbers I used are based on the majority views from many such discussions.

It doesn't mean they're right though. I mean the majority of UK voters thought a Tory government was a good thing

I wasn't paying much attention, wasn't concerned, didn't care ('cause we can care too much sometime), was following other rules you'll see (like 2 x RAM or 1.5 x RAM), and generally knew it was OK. Almost certainly, you probably will not need the full 8 GB, so we are on the safe side -- assuming you can afford the space, which it looked like you had plenty to spare. And so on.

In the future, I would hang on to and refer to these guidelines and rules of thumb:

Please not in the Code box of post #36 the Slab partition highlighted in red.

and you can edit that text, too, adding red or bold-face, or introducing blank lines for readability between command blocks, etc.

Please forgive me, I can't resist:

Just had to do it.

[logan01]

I keep a note pad nearby to write down new commands I come across. Then when I have time, I type them up and print out.

Commands is what that how-to you cited (yesterday) is all about:

https://www.kubuntuforums.net/showth...sole-Beginners

If you have questions, you can always post them here in the main forums (better than posting in the how-to section), like you are doing now, under New Guy or Misc. or catch-all, etc.

Duh. I even have that link on my Bookmarks bar.

[Qqmike]

I will learn this, though, ya'll may suffer through the process. Thanks again everyone for all the help. Priceless.

People like to help. It keeps us on our toes, and you can always learn something new by helping out.

[Qqmike]

This was it:

cd / && sudo find -name *grub*

There are always more clever ways of writing these things, too! I tend to be not-too-sophisticated, more straightforward, basic, "naive" ... easier to understand when you try to read it after some months pass!

Good deal. Great name oshunluvr. Me too.

Mike: My latest power command is learning to use "find". I swear it's the most powerful tool at the command line if you know how to use it.

Funny, me, too, just lately. I needed to find ALL references to "grub" on my system (for that how-to I wrote about removing GRUB), and "find" was perfect for that, with *grub* as the -name.

I play with it when I'm not learning postgresql...

Yeah, I used to keep a text file in my desktop folder that I would open up and put in commands as I learned them. These days, most are stuck in my head - the simple ones anyway.

I'm an old DOS guy from waaaay back. To me, there's so much more you can do from the command line (aka in a terminal) and you get more information back usually. I seem to default to the terminal for system "house-keeping" tasks rather than trying to dig through some GUI somewhere.

If you're going to play a lot with terminal commands, I recommend a program called "yakuake" to make it quick and easy. It's a drop down terminal that appears when you hit F12 and goes away when you're not using it.
