[sorted out] Add filenames to top of each files in a directory

Hello,

I tried different solutions given in various linux portals but no luck..

The directory consists of files with no-extension.
Each file has only one line. I need to add each filename to the top of each file so eventually each file will have two rows.
Filenames have spaces between words and some files have multiple spaces at the end of their names.


At first I tried this one:

Code:
while read F ; do
grep sed  -i '1i $F' $F > $F.txt
done


Also below one is not working:


Code:
for filename in $(ls $*)
do
	sed "1s/^/${filename} \n/" ${filename} > $filename.txt 
	echo Done ${filename} 
done

sleep 2


Any help will be appreciated

Kind regards
Boris

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
