Removing newline at end of file using bash shell script

I am trying to remove the last newline added to the file using bash script. I have got this - truncate -s $(($(stat -c '%s' foo.txt)-1)) foo.txt

here foo.txt the file name. but I want to parametrize the file name, I will pas the file name to the script and it should this remove the newline at last from that file. Request your help on this. I do not have linux in my machine and tried using cygwin but it is giving error while running the script.

Thanks

To remove last line if it is newline use this sedL

sed -i.bak '/^[[:blank:]]*$/{$d;}' foo.txt
