@hackage haskdeep0.2.0.1

A command line application that computes file hashes traversing recursively through a directory structure.

The known hashes can be used to audit the same directory structure or a copy of it.

Execute haskdeep without arguments and it will show you the help text:

user@host:~$ haskdeep

 Usage: haskdeep COMMAND [-c|--computation MODE] [-r|--root DIRNAME] [-k|--known FILENAME]
   Computes hashes and audit a set of files

 Available options:
   -h,--help                Show this help text
   -v,--version             Show version information
   -c,--computation MODE    md5 | sha1 | sha256 | skein512 - default md5
   -r,--root DIRNAME        Root directory - default current directory
   -k,--known FILENAME      Known hashes file - default known.haskdeep
   -e,--excl-regex REGEX    Exclude files or directories based on regex
   -f,--incl-mod-from DATE  Include files modified from yyyy-mm-ddThh:mm:ssZ
   -t,--incl-mod-upto DATE  Include files modified up to yyyy-mm-ddThh:mm:ssZ

 Available commands:
   compute                  Computes file hashes and saves them to known hashes file
   audit                    Audits files comparing them to known hashes

Default usage:

1. create known hashes of files contained in a root directory (traversed recursively)

 user@host:~$ haskdeep compute -c md5 -r myimportantfiles/ -k knownhashes.txt -e "tmp|\.log"

1. verify a copy of the same files comparing them with known hashes

 user@host:~$ haskdeep audit -c md5 -r copyofmyimportantfiles/ -k knownhashes.txt -e "tmp|\.log"
