Howto Boot UBUNTU ISO From Hard Drive

2012-08-15T07:18:00.000+05:30

Hope your Ubuntu ISO is in your home directory. Open a terminal and run:-

:~$ sudo mkdir -p /boot/ubuntu

Move your ubuntu.iso to newly created Ubuntu folder:-

:~$ sudo mv ubuntu.iso /boot/ubuntu/

Now you have to prepare grub menu to boot your ISO from hard drive:-

:~$ gksu gedit /etc/grub.d/40_custom

Paste this into the empty portion of the '40_custom' file:-

menuentry "UBUNTU ISO" {

set isofile="/path/yourisoname.iso"

loopback loop (disk,partition)$isofile

linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile noprompt noeject

initrd (loop)/casper/initrd.lz

}

Before saving the above file, you have to give the correct path of your ISO file:-

:~$ sudo fdisk -l

See this output:- /dev/sda3 90318848 202430463 56055808 83 Linux

Here 'sda' is 1st had disk and '3' is partition number. Change the above file according to your own output like this and save:-

menuentry "UBUNTU ISO" {

set isofile="/boot/ubuntu/ubuntu.iso"

loopback loop (hd0,3)$isofile

linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile noprompt noeject

initrd (loop)/casper/initrd.lz

}

:~$ sudo update-grub && sudo reboot

Schedule your programs with CRON Command in Linux

2012-07-23T05:27:00.000+05:30

Cron is a time-based job scheduler in Unix-like computer operating systems. Cron enables users to schedule jobs (commands or shell scripts) to run periodically at certain times or dates. It is commonly used to automate system maintenance or administration, though its general-purpose nature means that it can be used for other purposes, such as connecting to the Internet and downloading email.

Here we will see how to schedule some Downloader softwares
with the help of “cron”. Open a terminal and run.

:~$ export EDITOR=gedit

:~$ crontab -e

Now paste the following files into the pop up file and save it.

# m h dom mon dow command
# Start Torrent client, please replace with correct path of your torrent program at your required time
15 2 * * * DISPLAY=:0.0 /usr/bin/deluge
# Replace with correct path of download.txt and fill it with your links. Install wget before using the command
17 2 * * * wget -ci /home/username/downloads.txt
16 2 * * * DISPLAY=:0.0 /usr/bin/jdownloader
