Vi is complaining that the last line in the file does not have a terminating newline. Running all of your files through the awk programme that you mentioned will fix the ones that are missing the newline, and will not change the ones that are ok. That is the easy way.

If you really want only to alter just the files that are missing the terminating newline, then try this out:

Code:
#!/usr/bin/env ksh

for x in *
do
        if ! tail -1 $x | od -t x1 | grep -q "0a$"
        then
                echo "fixing $x"
                echo "" >>$x
        else
                echo "$x is ok"
        fi
done

It will run the last line of each file in the current working directory through od, and if the last byte is not 0a (newline), then it will add a newline to the file. Using the echo will be faster as kshell will open and seek to the end where awk would read and write all of the lines in the file -- unnecessary disk i/o.

This should work in bash too, but I didn't test it there.
