checking digest of one file

05-09-2011, 06:55 PM

Hi All -

I can't figure out how to see and validate a specific file digest on my Fedora 14 system; I think I must be missing something simple.

Here's a quick example of what I'm trying to do:

[user@host]$ rpm -q --dump coreutils |grep bin/ls
/bin/ls 109208 1288784582 def61ac5ca608ba6f41eb08aa3eaa0b2274a67512938030830 051d792fb3946e 0100755 root root 0 0 0 X
[user@host]$ sha256sum /bin/ls
881282512562ad22095371f0865be66f5424b7590e6c73eb15 aae884cf9edd1c /bin/ls

Why doesn't the digest match? 'rpm' says the package is fine:

[user@host]$ rpm -V coreutils
[user@host]$ echo $?
0

Thanks.
Aaron

prelink? (something which rpm handles).

Yes! Thanks Rex for the clue.

Solution:

[user@host]$ prelink -y /bin/ls |sha256sum
def61ac5ca608ba6f41eb08aa3eaa0b2274a67512938030830 051d792fb3946e -
[user@host]$ rpm -q --dump coreutils |grep bin/ls
/bin/ls 109208 1288784582 def61ac5ca608ba6f41eb08aa3eaa0b2274a67512938030830 051d792fb3946e 0100755 root root 0 0 0 X
