sed: append text to a line before the end line?

[PryGuy]

Good day to you all!
I have a question, I have to append a line to a line prior to end, so the text would look:
Old Line
Old Line
Old Line
NEW LINE!
Old LineIt's not as simple as I figured... Thanks in advance!

[unutbu]

awk '{new=$0; print old; old=new}END{print "NEW LINE!"; print old}' file

Thank you, unutbu! You help me for the second time! :)
But is it impossible for the sed almighty? It's such an easy task... :(

Hi,
In sed:
sed '$iNew Line!' somefile

Hi,
In sed:
sed '$iNew Line!' somefileThis will add line to the very end as far as I get it...

Hi, no $i inserts before the last line. $a would append after the last line.

So:

xxx@xxx:~/tmp$ cat testfile
firstline
second line
third line
xxx@xxx:~/tmp$ sed '$iNew Line!' testfile
firstline
second line
New Line!
third line

awk '{new=$0; print old; old=new}END{print "NEW LINE!"; print old}' file
This code quite tricky. Unfortunately, there is one bug that it insert one blank line at the first line of the file, for "old" is empty when gawk is processing the first line.


sed '$i \
yourinsertedtext' fileThis one is the one that should be used, for it is rather simple.
