Hey Rochit...

As a one-liner, It looks like a convoluted way to prepend a carriage return to the text input from "file_name" (which would be the path to your text file). The same result can be obtained many ways, one would be:

awk '{print "\n" $0}' file_name

The text of file_name is assigned to $0, which is concatenated with the carriage return "\n" and printed to the screen.

The example you provided just adds the variables x and y. x is assigned the text value of the input for $0. Then a carriage return "\n" is prepended to x. Then x is assigned to y, which is printed to the screen.

Hope this helps some....Cassj
