Finding line numbers of blank lines
|
| |
Sometimes I have files which are double-spaced and I use
awk 'length > 2' file
to strip away the blank lines.
Now I have some blank lines within a file and I would like to know the line numbers on which they occur. I thought that I could do something like:
awk '{length < 5} print NR' file... more »

$ awk '{printf $0, "foo"}' file1
\nfoo\n$
I was expecting to see the "\n"s turned into newlines! I tried
