Exercise 1 - Create and Change Hard and Symbolic Links

Sometimes, you may require a file to be accessed from multiple locations on a filesystem. One option is to create multiple copies of the source file. However, it will take much more space and also if the source file is updated, you would need to update the copies at all locations. Another option is to create a link of the source file at each required location. A link carries the metadata to the filesystem and is linked with the source file. These links can be hard links or symbolic links.

In this exercise, you will understand how to Create and change hard and symbolic links.
