Command is - sudo gedit /boot/grub/menu.lst

This will show output as -
## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default 0

The important line is the last one. You will need to change that number 0 to match the Windows boot section. Typically it's always going to be 4 on a default dual-boot configuration. Change this value to 4, and then save and reboot your machine. You should go into Windows instead of Ubuntu automatically.

Hard Link
when a file is copied, both the original and copy occupy separate space on the disk.
unix allows a file to have more than one name and yet maintain a single copy on the disk. The file is then said to have more than one link or name, but all have the same inode number. This is called hard link. All attributes are identical any modification or change in one file is automatically available in the linked file. It provides some protection against accidental deletion. Let there be a file named restore.sh. You need to create another file which provides?as backup to the original file. By creating a link, you create a backup.
unix command used to create hard link?>>ln- backup.sh restore.sh

Soft Link
It doesn't have the file's content but simply provids pathname of that automatically has the contents. This is called as softlink. but incase the original file is deleted we can't get the file's content from the linked file, coz, it just provides the path name of the file. This is also known as symbolic link. Windows shortcuts?are more like symbolic links. The original file and the linked files have different inode nos.
Unix command used to create soft link>>ln-s

Cat displays file contents. If the file is large the contents scroll off the screen before we view it. So command 'more' is like a pager which displays the contents page by page.
