Not clear if you need this to run as a single script or not, but here is 1 solution:

Code:
# oldest folder used analysis and version log created
dir=/home/cmccabe/Desktop/NGS/test

find "$dir" -maxdepth 1 -mindepth 1 -type d -printf '%T+\t%P\0' | sort -rz |
while read -r -d $'\t' time && read -r -d '' filename
do
    printf "The oldest folder is $filename, created on $time and analysis done using v1.3 by $USER at $(date "+%D %r")\n"
    awk -v FL="$filename" '
         FNR == 1 {filenum++}
         filenum==1 && index($0, FL) { 
              match($0, "_0*([0-9]+)/")
              FNUM=substr($0,RSTART+1,RLENGTH-2)
              gsub(/^0+/,"", FNUM)
          }
          filenum==2 && $0 ~ FNUM".pdf$"' input link > output
    break
done

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.
