Question

A student wishes to create symbolic links in a computer system running Unix. Three text files named "file 1", "file 2" and "file 3" exist in her current working directory, and the student has read and write permissions for all three files. Assume that file 1 contains information about her hobbies, files 1 contains information about her friends and file3 contains information about her courses. The student executes the following sequence of commands from her current working directory

In -s file1 file2
In -s file2 file3

Which of the following types information would be lost from her file system?
I. Hobbies II. Friends

Answer 1

In unix system : $ In - s file 1, file 2 command replace existing file 2 by file 1. If file 2 exist then it is first removed then replace with file 1.
In - s file 1 file 2
In - s file 2 file 3

So, file 2 replace file 3 the file replace file 2 i.e. friends and courses are lost and hobbies are remaning.
