Unbeknownst to some of us, Klaus K included a useful new command-line
feature in Version 7.4 Knoppixes.

This is to provide an example of a new capability in Knoppix 7.4 to create
a LiveUSB directly from a downloaded Knoppix LiveCD- or LiveDVD- iso,
without first actually making a LiveCD or LiveDVD for that iso.

Using a Knoppix 7.4 LiveCD, LiveDVD or LiveUSB command line


flash-knoppix KNOPPIX_V7.4.2DVD-2014-09-28-EN.iso
brings up a usage chart which will allow creating a 7.4.2 LiveUSB directly
from this iso definition, which if correct and found, doesn't itself need repeating.
The usage chart looks like this:


Usage: /usr/bin/flash-knoppix [-a] [-f] [-m i|p|n] [-p mb] [image|dir] [target_device]
-a Allow fixed disks
-f Force overwrite, no questions (batch mode)
-m i Method: Create overlay image
-m p Method: Create overlay partition (recommended)
-m n Method: No overlay (read only)
-p mb Overlay partition or image size in MB >= 200
image.iso Loopmount source ISO file
dir Source data directory containing files
target_device Destination block device (flash disk)

For my 16 Gb SanDisk at /dev/sdc and my iso at /media/sda3/isos, and
assuming 5 Gb for reiserfs persistence, the usage which worked was:


/usr/bin/flash-knoppix -m p -p 5000 /media/sda3/isos /dev/sdc

FWIW, I download & keep my isos on a Win7 ntfs partition.

@ utu

Thanks for your interesting tip, unknown to me and probably to many.

Now rather off topic, I notice that the text of your post covers less than half of the left-hand side of the page and the visible parts of the code boxes are shrunk and require much scrolling. This happens when reading with Firefox or Chromium, not with IE.

I also see this weird display with other contributors from time to time.

Regards.

I don't care for text running from side-to-side on an hd display, so I compose
off-line in a text editor usually.

I should probably learn how to shorten the width and extend the height of some
of the forum editor's forms; I have't take the time to do so.

Forum editor code & quote keywords help preserve whitespace, where it is useful in
conveying what's actually seen on a terminal.

Perhaps you can give us some good non-weird examples to guide our efforts.
I didn't see any among your 41 posts so far.

..and the visible parts of the code boxes are shrunk and require much scrolling.This is not a bug of the Forum software.Whether you have to use horizontal scrolling or not for the code-box depends on your local situation: size of the monitor (for example 10 or 22 inch), of the used browser (most of them interprets HTML code a little different) and - very important - of the used font and fontsize within the different browsers.

@utu

I do not see this happening with any of 'my' own posts. But to illlustrate, it is the case with post #1 of this thread, but not witth posts #2,3 and 4 .

@ Werner

I use a 17" monitor and my font faces & sizes are normal.

It is only a trivial matter. Other readers of Knoppix forums must have had a similar experience at times but nobody bothered to report it...

Oh, I see. In posting #1 there are hard-coded line feeds at the end of the lines produced with an editor software. Other posters (me to) uses only paragraphs and let the HTML software do the automatic wordwrap.

If somebody creates his posting within an editor first, he should use an editor like for example Geany with the ability of visual linebreak.

I use a 17" monitor and my font faces & sizes are normal.What is "normal"? If I use a fontsize 10 I don't need horizontal scrolling for the codebox of posting #1. but with fontsize 16 i have to scroll.

Hello, utu.
I'm on Knoppix 7.7 trying to create a LiveUSB on a 32Gb pendrive for Knoppix 8.1 using flash-knoppix.
My .iso file is here

knoppix@Microknoppix:~/Downloads/Torrents/KNOPPIX_V8.1-2017-09-05-EN$ ls
knoppix-cheatcodes.txt
KNOPPIX_V8.1-2017-09-05-EN.iso

My pendrive is here:

knoppix@Microknoppix:/media/sdc1$ pwd
/media/sdc1

When I type

/usr/bin/flash-knoppix -m p -p 20000 /home/knoppix/Downloads/Torrents/KNOPPIX_V8.1-2017-09-05-EN/KNOPPIX_V8.1-2017-09-05-EN.iso /media/sdc1
the OS says

mount: /media/sdc1: failed to setup loop device: Invalid argument

and when typing sdc instead of sdc1 it answers giving the usage of flash-knoppix.

Any suggestion, please?

@Porteņo (http://knoppix.net/forum/members/90009-Porte%C3%B1o): /media/sdc1 is the mountpoint where you have mounted the file system in partition 1 on the sdc device. /media/sdc does not exist.

flash-knoppix wants a device to write on, not a file system. I guess that all partitions on the device must be unmounted to make the device available for writing.

Try this:
umount /media/sdc1
/usr/bin/flash-knoppix -m p -p 20000 /home/knoppix/Downloads/Torrents/KNOPPIX_V8.1-2017-09-05-EN/KNOPPIX_V8.1-2017-09-05-EN.iso /dev/sdc

Thank you, it worked!

I'm having some issues with knoppix 8.1, after checking file integrity will ask to the community.
