Occasionally you will need to make a link to a file or directory in Linux. To create a symbolic link you will need to use the ln command, which will follow the form of;
ln -s <target> <link name>
Example: Assume you frequently use gnome-calculator and decide you want a link on your desktop so you can quickly start that application in the future. To accomplish this with a symbolic link you could do the following;
ln -s /usr/bin/gnome-calculator ~/Desktop/calculator
You can also update an old symbolic link by overwriting the link using the following command.
ln -sf /usr/bin/gnome-calculator ~/Desktop/calculator
or when linking to directories you will need to include an n option
ln -sfn /mydir/ linkname
