vim remove LF at the end
 

I start up vim and type 4 characters 'asdf', no Enter at the end..
however when I save the file, it is 5 bytes long, containing 'asdf' + linefeed character..
how can I make vim not to append the LF character at the end of my file?
thanks for your help..

If you hadn't already solved your problem...

After having saved with vim the file, from console:

cat file |head -c -1 >file #remove last character from file

thanks.. this is great..
I have not solved it with vim, but this really helps..
thanks again

To avoid appending the extra char in vim, you need to set the binary and noeol options, i.e:
:set bin
:set noeol
then save your file. You can add these commands to your .vimrc if you will want them for every file, but I think this case would normally be the exception.

thanks.. this is great
