prints line numbers

sed '/./=' infile | sed '/^/N; s/\n/ /'
There's too many options to number, My curiosity has forced me to make it using only sed. Maybe useful... or not... :-S

What Others Think

@glaudiston: I like the sed version. I tried but couldn't figure how to get rid of the extra line feed caused by =.

I'm not keen on this version. I have found instances where the numbers end up at the end of some lines. Also no numbers are provided for blank lines.

putnamhill and igc, try this way: cat infile | sed "/^/=" | sed "N;s/\n/. /"
