I'm searching for a script which creates a md5 chechsum file for every single folder inside drive recursivley?

I do have a copy of md5deep on my machine but I'm not that good in scripting bash.

    Why do you need a script if you have md5deep, why not just md5deep -r [folder name]?

    Because md5deep creates one file with all checksums. What I want is a md5-file for every single file. For Example: document1.doc document1.md5, document2.doc document2.md5 and so on.

  • That's an unusual thing to want - most people go with either one file with all checksums, or one file per directory with all the files in that directory.

  • So it's not possible?

To get a .md5 file for any files under a specific directory, you can use the following script:

if [ $# -ne 1 ] ; then
        echo "Usage $0 [directory]" 
        exit 1
find $1 -type f  -print0 | while IFS= read -r -d $'\0' file; do
    cd "$(dirname "$file")"
    filename="$(basename "$file")"
    md5sum "$filename" > "$filename".md5

In zsh, the same for all files under the current directory can be done with the one-line command (includes files starting with a dot):

for i in **/*(/D) ; do ( cd $i ; for j in *(.D) ; do md5sum $j > $j.md5 ; done ) ; done

Necromancy sure, but I know how we love 1 line-ers

#find / -type f  -exec md5sum {} + > CheckSums

personally I would use sha512sum, and limit to /home or something but if you want to checksum root then go for it.
