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

bashbug

BASHBUG(1)						      General Commands Manual							BASHBUG(1)

NAME

       bashbug - report a bug in bash

SYNOPSIS

       bashbug [--version] [--help] [email-address]

DESCRIPTION

       bashbug	is  a shell script to help the user compose and mail bug reports concerning bash in a standard format.	bashbug invokes the editor
       specified by the environment variable EDITOR on a temporary copy of the bug report format outline. The user must fill  in  the  appropriate
       fields  and  exit  the  editor.	 bashbug  then	mails the completed report to bug-bash@gnu.org, or email-address.  If the report cannot be
       mailed, it is saved in the file dead.bashbug in the invoking user's home directory.

       The bug report format outline consists of several sections.  The first section provides information about the  machine,	operating  system,
       the  bash  version, and the compilation environment.  The second section should be filled in with a description of the bug.  The third sec-
       tion should be a description of how to reproduce the bug.  The optional fourth section is for a proposed fix.  Fixes are encouraged.

ENVIRONMENT

       bashbug will utilize the following environment variables if they exist:

       EDITOR Specifies the preferred editor. If EDITOR is not set, bashbug defaults to emacs.

       HOME   Directory in which the failed bug report is saved if the mail fails.

       TMPDIR Directory in which to create temporary files and directories.
