How to format a hard drive on Ubuntu 12.04 using Fdisk


Today I will show you how to format a hard disk using Fdisk.  Fdisk comes already installed on most modern Linux distributions by default.

For the purpose of this tutorial I will be using Fdisk on Ubuntu 12.04 to format a 16Gb USB penstick with the ntfs file system.

First we need to see what our 16Gb USB penstick is mounted as so open up a terminal and type:

sudo fdisk -l

and type your password when prompted.  You should get a screenshot similar to the one below.

In this case my 16Gb USB penstick is mounted at /dev/sdc1.

Next type:

sudo fdisk /dev/sdc1

and you should get the command prompt shown below.

Now we need to check the existing partitions on the penstick so type:

p

to get the screenshot below.

Now we know what is on the drive it is time to delete it so type:

d

You will then be asked for the partition number (1-4).  In my case I have 4 partitions on the disk and I need to delete them all.  So I will type 1 and this will erase the 1st partition only.  I would then be left with partitions 2 – 4 and to remove these I would repeat the procedure until all the partitions have been erased.

We now need to set up the new partition so in your terminal type:

n

Because this is the first partition on the drive type:

p

You will now be asked for a partition number.  Choose 1 and then press return.  When asked to specify the First Sector choose the default by pressing Return.  Again accept the default Last Sector by pressing Return.

Now that the partition parameters have been specified we need to write them to the hard drive and we do that by typing:

w

All that is left to do is to make the filesystem on the hard drive and to do that we type:

sudo mkfs -t ntfs /dev/sdc1

Next time I will show you how to accomplish the same task using GParted (for those who like a GUI).

How to configure Startup Applications in Ubuntu 12.04


Today I will show you how to configure startup applications in Ubuntu 12.04.

On your desktop go to settings (cog in the top right of the screen) and click on Startup Applications.

You will be shown a list of all the programs that are configured to start at boot time. Click on Add.

For the purpose of this tutorial I will configure Libreoffice to start at boot.   In the screen shot above I have configured the following:

Name – Libreoffice

Command – /usr/bin/libreoffice (all programs are stored in /usr/bin so use this command)

Comment – Office Suite

Once configured click Add.

Restart the system and your chosen program with start at boot.

How to schedule a backup in Ubuntu 12.04


Today I will show you how to schedule a backup in Ubuntu 12.04 using cron.

The cron daemon uses the crontab file  (think Task Scheduler in Windows) which allows you to set the backup schedule. The beauty of using cron is that it works ON ALL LINUX DISTRIBUTIONS not just Ubuntu. You don’t even need to install cron as it comes installed by default.

Ok time to get your hands dirty.  Open up a terminal and type “su” and when prompted enter your root password.  Next you want to open up the crontab file so type “nano /etc/crontab” in a terminal.  The crontab file should look similar to the table below.

 

M H Dom Mon Dow User Command
1 9 * * * Root Tar -cvf/media/dev/sdb/backup.tar /home

Where:

M = minutes

H = hours

Dom = every day in the month

Mon = every month

Dow = every day of week (e.g 1-5 would be Monday to Friday inclusive)

User = user who can perform this task

Command = what is getting backed up and where is it getting sent to

Lets explain this a bit. In the above example I have backed up a folder called home (/home) to a folder called backup.tar which is on sdb (/dev/sdb/backup.tar) at 1 minute past 9 everyday in the month, every month.  The authorised user is root and the command to be used is Tar -cvf.

When you have configured the crontab file save it and exit.  Your backup schedule is now set.
