Can you be more specific? You could use a bash script to run an md5sum against a file and do just about anything with the output for you to review.

adamhealy, is md5sum support sha256, if not, where can i get sha256 from?

 

by: adamhealyPosted on 2009-10-21 at 18:09:15ID: 25629992

Does you system have the required libraries to run an sha sum? If so the below link might help. You can specify bit length with the -a switch.

This might help:

How about this one:

http://www.alwanza.com/howto/linux/tripwire.html

Tripwire is a program that helps Linux Administrators detect "unauthorized activity" on their computers by creating a database of all the files on the computer, including information about each file's size and last modification date.  The Administrator sets up regular times to check the files on the computer against the records in the database and uses the generated information to determine if any of those changes require further investigation.
