| | Well... now I'm curious.
| |
| | How would you delete ONLY the next-to-last line,
| | leaving the previous very last line to replace
| | the space where the next-to-last line was just
| | removed?
|
| Badly phrased question. If you remove a line, there is no "space left
| behind". There would only be a "space left behind" if you deleted the
| just the line's visible contents, AKA as blanking the line. When one
| says remove, one means removing the 'newline' as well, so that there's
| nothing left at all.
|
| In any case, what you meant to do would want a small modification to what
| Bill just posted:
|
| ex - filename <<DONE
| $
| -
| w
| q
| DONE
|

JP,
We've know each other for a long long time. If you were able
to "fix" me from making all those typos, confusing explainations,
questionable questions, etc, I would have had a sex change and tried
to marry you long ago. Please don't mention this to Jane. For those
of that don't know me, I'm a mans man, so don't even think about what
your thinking <g>.

The one hyphen is the difference between what you posted above
and what Bill posted. So, what would be the case if:
###---------------------------------------------------
ex - filename <<DONE
$
- Removes next to last line (from previous post)
- Add another hyphen to rm the next-to-next last line ?
Add 5 more to remove another 5 lines ?
w
q
DONE
###---------------------------------------------------
IOW: What if one wanted to remove the last 6 lines, but
keep the very last line? I understand if your to busy,
but I find this issue really interesting for some reason.
