I am trying to locate a tool, not unlike either the "sfc" command on Windows or the "sysck" command on AIX, which can verify that the file contents, ownerships and permissions are correct. The "replace damaged or missing files" functionality in "sfc" isn't what I'm looking for, it's the "verify that all the right parts are in all the right places" capabilities.
The task I'm trying to perform is verifying that a number of different installation and upgrade paths to a specific software release on an embedded Linux product reach the same overall filesystem state -- all the required files and directories exist, have the correct contents (as told by md5sums or similar), owner, group and permissions.
A collection of individual commands -- find, stat, test, etc. -- isn't what I'm looking for. I'm looking for a TOOL, such as either of the ones I mentioned above.
I've searched high and low, but so many of the searches turn up "fsck" that any positive hits are being buried.
