This is mostly for my own notes but this command will compute a md5 message digest from the command line. You can also replace md5sum with other checksum commands (e.g., sha1sum) Show Sample Output
extracts path to each md5 checksum file, then, for each path, cd to it, check the md5sum, then cd - to toggle back to the starting directory. greps at the end to remove cd chattering on about the current directory.
Replace "user/sbin/sshd" with the file you would like to check. If you are doing this due to intrusion, you obviously would want to check size, last modification date and md5 of the md5sum application itself. Also, note that "/var/lib/dpkg/info/*.md5sums" files might have been tampered with themselves. Neither to say, this is a useful command. Show Sample Output
Filter entries in OpenSuse /var/log/messages like: timestamp servername kernel: [83242.108090] btrfs: checksum error at logical 1592344576 on dev /dev/sda5, sector 5223584, root 5, inode 2652, offset 282624, length 4096, links 1 (path: log/warn) Show Sample Output
btrfs checksum errors console report. Show Sample Output
As output, checksums and filenames will be printed.
Nothing special about hashing here, only the use of cut, I think, could result at fewer keystrokes. Show Sample Output
Doesn't create a file Make sure to list the files / directories in the same order every time.
