I have this scenarios:
File Content:
10.1.1.1
10.1.1.2
10.1.1.3
10.1.1.4
I want sed or awk so that when i cat the file every time new line is returned.
like
First iteration:
cat ip | some magic
10.1.1.1
Second iteration returns
10.1.1.2
Third iteration returns
10.1.1.3
Fourth iteration returns
10.1.1.4
and after n number of iterations, it returns to line 1
Fifth iteration returns:
10.1.1.1
Can we do it using sed or awk.
