General :: Output Md5 Or Sha1 Along With Fullpath And Filesize

I am trying to output md5 or sha1 along with fullpath/filename and file size but I dont seem to find a way to do this.

with

Quote:

find . -printf '%s %p'

i can retrieve size and fullpath and filename

however I am not able to merge that info with the md5 or sha1 of the file

my aim is to have a file such as this

6435b607f86b6e6be1e77bb3b1987677d1377275 ./abc/asda/file1.txt 404
6435b607f86b6e6be1e77bb3b987677d13772725 ./abc/asda/file2.txt 1404

also, performance is an issue for me, since i need to get the info out of 10m files (approx 6TB), so commands like find are preferred and less iterations among commands would be great too.

btw i've tried to use something like this

Quote:

find . -type f -printf '%s %p'| xargs awk '{x=system("md5sum "$2)}END {print x" "$2" "$1}'

but variable x contains the return value of the system command md5sum and not the stdout
