http://www.ubuntugeek.com/upgrade-ubuntu-610-edgy-eft-to-ubuntu-704-feisty-fawn-2.html

Method 2 – Using apt-get

Edit your /etc/apt/sources.list as root. Change every occurrence of edgy to feisty.

Use any prefered editor. If you have a CD-ROM line in your file, then remove it.

sudo vi /etc/apt/sources.list

or

use the following Simple command

sudo sed -e ’s/\edgy/ feisty/g’ -i /etc/apt/sources.list

Now you need to update the source list using the following command

sudo apt-get update

Upgrade using the following command

sudo apt-get dist-upgrade

Double check your process was finished properly using the following commd

sudo apt-get -f install

sudo dpkg –configure -a

Now you need to Reboot your machine to take your new ubuntu 7.04 installation to effect all changes.

Testing Your Upgrade

You can check the ubuntu version installed using the following command

sudo lsb_release -a

Output Looks like below

Release: 7.04
Codename: feisty

or

Just type the following command in your terminal

cat /etc/issue

Output Lokks like below

Ubuntu feisty (development branch) \n \l

Some Useful queries:

select WEEKDAY(starttime), SUBTIME(time(starttime),time(endtime)) from devicespan limit 200;

Weekday = number of the weekday.
Time = to convert date-time format to time only.
Subtime = subtract the two times.

networking in a brand new way.

First of all i will split the file into 10GB pieces. The file name is: enwiki-20070908-stub-meta-history.xml

fawad@crete:~/wiki$ split -b 4000m enwiki-20070908-stub-meta-history.xml

Now i will copy a piece by piece into my seagate external hardrive. I am copying this file from a remote server to my machine

root@fawad-laptop:/home/fawad# scp fawad@crete.ex.nii.ac.jp:/home/fawad/wiki/enwiki-20070908-stub-meta-history.xml /media/usb0/niidata/split/
fawad@crete.ex.nii.ac.jp’s password:
enwiki-20070908-stub-meta-history.xml 10% 4091MB 10.5MB/s 57:03 ETAFile size limit exceeded (core dumped)
This means only files less than 4GB are supported. So i again spilled the files to 4GB file each.

Another important thing to note is that i had to use root login to copy file to my external seagate USB hardrive.

Now once i have splited the files into 4GB chunks. Now use the following command to copy all the files from this folder to one of the folder in the seagate harddrive.

fawad@Ubuntu-01:/etc/hotplug$ echo ‘blacklist orinoco’ | sudo tee -a
/etc/modprobe.d/my_blacklist
blacklist orinoco
fawad@Ubuntu-01:/etc/hotplug$ echo ‘blacklist orinoco_cs’ | sudo tee
-a /etc/modprobe.d/my_blacklist
blacklist orinoco_cs

Where orinoco_cs & orinoco are the modules names.

The above tutorial will blacklist the kernel modules at the starup. But you modules might be loaded which anything is hotplugged into your computer.

For that i could not actually come-up with a solution but i think the way is to intsert modules names in the file:

root@Ubuntu-01:/etc/network# more /etc/hotplug/blacklist

fawad@Ubuntu-01:~$ more /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with “#” are ignored.

dpkg – a medium-level package manager for Debian
————————————————

This is like an rpm for Red-hat linux.

Man Page: http://www.fifi.org/cgi-bin/man2html/usr/share/man/man8/dpkg.8.gz

To list packages related to the editor vi:
dpkg -l ‘*vi*’

To search the listing of packages yourself:
less /var/lib/dpkg/available

To remove an installed elvis package:
dpkg -r elvis

To install a package, you first need to find it in an archive or CDROM. The “available” file shows that the vim package is in section “editors”:
cd /cdrom/hamm/hamm/binary/editors dpkg -i vim_4.5-3.deb
