Recursively md5sum all files in a directory tree

After a server crash a wanted to compare all actual files with the backuped data. An easy way is to compare the md5 hashes like that:

First create recursively md5 hashes from all files in that directory:

find ./backup -type f -print0 | xargs -0 md5sum > /checksums_backup.md5

Then check the actual data:

md5sum -c checksums_backup.md5

I was lucky, no files where damaged.

Läuft meiner Erfahrung nach oft schneller als xargs. Vielleicht in diesem Falle nicht ganz so relevant, aber für andere Fälle
