Full Discussion: Bash find : another problem with prune
Top Forums Shell Programming and Scripting Bash find : another problem with prune Post 303043673 by Chubler_XL on Monday 3rd of February 2020 03:20:57 PM

From the original post we have:
Code:
find path \( \
   \( [folder-condition A] \) -prune -o \
   \( [folder-condition B] \) -prune -o \
   \( [folder-condition C] \) -prune \
\) -o \( \
   \( [file-condition D] \) -o
   \( [file-condition E] \) \
\) -o -print

You have no folder pruning conditions and two file pruning conditions so, the find should have been:
Code:
find "$SEARCH_PATH"  \(
    -false
\) -o \( \
    \( ! -newer "$FILE_DATE_REF_DEB" \) -o
    \(  -newer "$FILE_DATE_REF_END" \)
\) -o -print

Which can be simplified to:
Code:
find "$SEARCH_PATH" \( ! -newer "$FILE_DATE_REF_DEB" -o -newer "$FILE_DATE_REF_END" \) -o -print

and further simplified to
Code:
find "$SEARCH_PATH" -newer "$FILE_DATE_REF_DEB" ! -newer "$FILE_DATE_REF_END" -print

This find is equivalent to the find from the original post which returned 32 elements.

Hope this helps you work out was is going on. Note that -prune only comes into the find when you have conditions that remove directories (and all files below them).

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.
