I am using a sed funtion as follows...

if [ $FILE_EXT = "txt" ]; then
AFILENAME="F"$FILENAME
sed '1i\
'$AFILENAME'\
' $FILENAME > $FNAME
rm $FILENAME
mv $FNAME $FILENAME

I basically need to insert the name of the file, as the first line of the same file, starting with F.

But the output i get, inserts the filename correctly, but has 3 spaces in front. also ther eis a newline after the first line is added, How do i avoid this. any help please.

Thanks..

Do the following to see if the spaces are in your variables or not:

echo FILENAME=[$FILENAME]
echo AFILENAME=[$AFILENAME]

You can remove one newline by doing something like this:

sed '1i\
'$AFILENAME'' $FILENAME > $FNAME

Best regards.
