I've a .txt file from which I'd like to delete the last, empty line. I've tried a ridiculous number of sed, perl and awk commands found on the internet, but none of them has worked.

I don't know what does it mean, but I leave you the output of od -c myfile.txt

od -c myfile.txt

How the hell can I delete that last, empty line?

  • Instead of `od -c myfile.txt` post the output of `cat myfile.txt | base64` – kbtz Mar 26 '16 at 22:56
  • Use the edit function for this, not the answer field. – Sven Mar 26 '16 at 23:04
  • If perl is avaiable in the system use `perl -i -pe "chomp if eof" myfile.txt` [source](http://stackoverflow.com/questions/4448826/removing-last-blank-line) If its not, we can make that damn sed to work... – kbtz Mar 26 '16 at 23:19
  • Where do you see a 'last, empty line'? You have text `192.89.3.8/30` then a newline (which together make up a nonempty last line) then end-of-file. – dave_thompson_085 Mar 27 '16 at 06:28

You can save the all content witot the last line in a new file:

sed '$d' myfile.txt >> myfile2.txt
