Using sed to show even numbers and the line
Hello, I have an assignment that requires us to use sed only. The first part of the assignment says to use a sed script to print only the even lines, but if it is print, the number of that lines needs to be printed before the text.

ex:

2
line 2 text

4
line 4 text

6
line 6 text


what I've tried is sed -ne '2~2p' filename | sed = filename

but that only shows:

1
2
line 2 text
3
4
line 4 text
et..
