## Exercise 3

 1. Write a script that:
    a. creates an empty file called ‹file.txt›,
    b. creates a symlink to this file, called ‹symlink.txt›,
    c. creates a hardlink to ‹file.txt› called ‹link.txt›,
    d. writes ‹foo› into symlink.txt,
    e. prints the target of ‹symlink.txt›.
    
 2. Write a script that:
    a. checks if the target of ‹alink.txt› exists,
    b. if it does, it prints the target,
    c. otherwise, it prints ‹alink.txt is broken›.
    
 3. Create a valid and a broken ‹alink.txt› and run the script from point 2 to
    check that it works.
