I'm wondering if there is an easy way making a md5 file for each on the directory or do i have to run md5sum for each file?

md5sum film1.iso > film1.md5
md5sum film2.iso > film2.md5
md5sum film3.iso > film3.md5

for f in `find . -type f`; do (md5sum ${f} > ${f}.md5); done

In a single command:

find -type f -exec md5sum {} \; >CHECKSUMS.md5

You can combine it with any other find options (man find for more info):

find -iname *.iso -type f -exec md5sum {} \; >CHECKSUMS.md5
(md5 of all filenames that match *.iso case insensitive from the actual folder)

find Music -iname *.mp3 -mtime -1 -type f -exec md5sum {} \; >CHECKSUMS.md5
(md5 of all filenames that match *.mp3 case insensitive in "Music" folder that have been modified in the last 24 hours)

Thanks

Any problem with spaces in the filename as it was in the first one?

And if I want to do more then a single command e.g. check if there already exist a md5 for the file

I don't know if there is any interest in the end result but here it is

#!/ffp/bin/sh
#-vx

if [ "$1" == "" ]
then
find -type f -exec $0 "{}" \;
exit
fi

if [ -d "$1" ]
then
find "$1" -type f -exec $0 "{}" \;
exit
fi

if [ -f "$1" ]
then
ffile=$1
Ext=${ffile##*.}

if [ "$Ext" != "md5" ]
then
Path=${ffile%/*}
file="./${ffile##*/}"
md5file="./checksum.md5"
cd "$Path"

if [ -f $md5file ]
then
grep -F -i "$file" $md5file > /dev/null
if [ $? -ne 0 ]
then
echo "md5sum $ffile"
#sleep 10
md5sum "$file" >> $md5file
else
echo "Done $ffile"
fi
else
echo "md5sum $ffile"
md5sum "$file">$md5file
fi
fi
fi
