I need a linux developer to solve couple of Tasks:

1) In any way ("manually" or by script) make sure that: there will be a file with the name HD in the directory tyden12, this file will contain a single line with your username, the output from command ls -l HD will contain the number 5 in the second column, there will be a maximum of 3 regular files, including an HD file, in the directory week12. 2)Create a shell script that creates a symbolic link string in this directory such that: the first link (e.g. named sln1) refers to the file /etc/hosts, the second link (e.g. named sln2) refers to the previous link sln1, the thirds link (e.g. named sln3) refers to the previous link sln2, and so on. The length of this string is specified by a number that is a parameter of the script. An example of a created string of length 3 is in the example below.
