I would like to insert "echo" followed by a number, but have the number sequentially increase on each line so that I can track where the computer is through my script. So I can pinpoint possible errors with data or my script.

eg, I want to make

line
line
line
line
line
....

into,

line
echo 1
line
echo 2
line
echo 3
line
echo 4
line
echo 5....

Is this possible using sed?
thanks

I don't think you can do that with sed, but you can do it with awk.

<edit>
It occurs to me that this might also work

Excellent, I just tried it - that is just what I was looking for!

I thought that I was going to only use sed as it is great, but looks like I am going to have to learn awk too

Thanks
