NAME
     snapshot-dir - create a snapshot  database  of  a  directory
     tree

SYNOPSIS
     snapshot-dir      [-vN]       directory       [directory...]
     [:output=database-name]                 [:old=database-name]
     [:devcross=true]


DESCRIPTION
     snapshot-dir

     Finds all files in the directory, recursively, and writes to
     the  [database-name]  or to standard output a description of
     each file including name, file modes, sizes, dates,  and  an
     MD5 checksum of each REG file, and the contents of each sym-
     bolic link.

     The database can be further processed by other programs that
     can determine what has changed in a file system.

     The directory arguments can also be regular file names.

     The -v argument lets you specify a verbosity level.

     If :old=database-name is given then the old database will be
     used  as  a  cache  of md5 values. The md5 of a regular file
     will only be recomputed for files which have been apparently
     changed  according  to the operating system reported status.
     Programs can of course modify a file and then set the status
     values  back,  so  do not use this technique during security
     audits.

     If :devcross=false is specified then all  entries  which  do
     not  reside  on  the same "device" as the starting directory
     will be ignored. This is useful for creating a snapshot that
     can be compared with a filesystem backup tape.
