Don C. provided, IMO, the best answer. Requires no extra files. Also works when the read program has issues and fails. It keeps the filenames unchanged. The files are not deleted after 15 days. You have to script that as well
I assume you use ksh -> #!/bin/ksh uses ksh as the shell

Code:

# "read_process" is your code or shell script to "read" the file
#    hopefully read_process returns failure when it fails
#!/bin/ksh
cd /directory/with/files
ls | while read fname   # get the name of every file in the directory
do
   if [ -s $fname ] ; then    # file has data in it?  it is not empty?
      read_process $fname   # not empty: run read_process
      if [ $? -eq ] ; then      # read_process ran ok?
         > $fname               # read_process worked make the file zero length (empty)
      fi
   fi
done

This script should be run once a week or maybe every day, as you decide. Do not change the 16 to a 15 or you will have problems - i'm not going into why fully but days are not dates they are the number of (86400 seconds) in the past. Not calendar days. I assume you want an email and have email on your UNIX box

Code:

#/bin/ksh
# assume that a file could keep failing on the read_process,so we keep it
find /directory_path_to_files -type f -mtime +16 -size 0 -exec rm {} \;
find /directory_path_to_files -type f -mtime +16 -size +1 > t.lis
if [ -s t.lis ] ; then
 uuencode t.lis t.txt | /usr/bin/mailx  -s 'you missed processing some files ' you@yourcompany.com  
fi

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).

FILES

       /etc/shells	       lists shells on system
