isolate unique files in a folder
Hello,

I have two folders.
One has 1183 text files (folder A).
The other (folder B) has 1160 of those 1183 files (the contents in these 1160 files are identical to the contents in the corresponding files in the other folder, but the names of the files in this folder are completely different from the names in the other folder)

I want to figure out which 23 files are missing in the second folder (presumably unix can examine each file in folder A and see whether or not folder B has a file with the same contents... and keep doing this until it finds the 23 files that are in folder A that are not in folder B).

How would I go about doing something like this ??

Any help, suggestions, or discussions would be greatly appreciated,

juliette salexa

rmf

RMF(1)                                                               [nmh-1.5]                                                              RMF(1)

NAME

       rmf - remove an nmh folder

SYNOPSIS

       rmf [+folder] [-interactive | -nointeractive] [-version] [-help]

DESCRIPTION

       Rmf removes all of the messages (files) within the specified (or default) folder, and then removes the folder (directory) itself.

       If  there  are  any  files  within the folder which are not a part of nmh, they will not be removed, and an error will be produced.  If the
       folder is given explicitly or the -nointeractive option is given, then the folder will be removed  without  confirmation.   Otherwise,  the
       user  will be asked for confirmation.  If rmf can't find the current folder, for some reason, the folder to be removed defaults to `+inbox'
       (unless overridden by user's profile entry "Inbox") with confirmation.

       If the folder being removed is a subfolder, the parent folder will become the new current folder, and rmf will produce  a  message  telling
       the user this has happened.  This provides an easy mechanism for selecting a set of messages, operating on the list, then removing the list
       and returning to the current folder from which the list was extracted.

       If rmf s used on a read-only folder, it will delete all the (private) sequences (i.e., "atr-seq-folder" entries) for this folder from  your
       context without affecting the folder itself.

       Rmf irreversibly deletes messages that don't have other links, so use it with caution.

FILES

       $HOME/.mh_profile          The user profile

PROFILE COMPONENTS

       Path:                To determine the user's nmh directory
       Current-Folder:      To find the default current folder
       Inbox:               To find the default inbox

SEE ALSO

       rmm(1)

DEFAULTS

       `+folder' defaults to the current folder, usually with confirmation
       `-interactive' if +folder' not given, `-nointeractive' otherwise

CONTEXT

       Rmf  will  set the current folder to the parent folder if a subfolder is removed; or if the current folder is removed, it will make "inbox"
       current.  Otherwise, it doesn't change the current folder or message.

BUGS

       Although intuitively one would suspect that rmf works recursively, it does not.  Hence if you have a sub-folder within a folder,  in  order
       to rmf the parent, you must first rmf each of the children.
