Rename files in a directory and move them
I have a directory e2e_ms_xfer/cent01
this contains the multiple files some of which will be named below with unique date time stamps
e2e_ms_edd_nom_CCYYMMDD_HHMM.csv
What I want to do is in a loop
1) Get the oldest file
2) Rename
3) Move it up one level from e2e_ms_xfer/cent01 to /e2e_ms_xfer
3) Process it
4) Move it down 2 levels to e2e_ms_xfer/cent01/done
4) Exit loop

This is what I have below but it does not do step 2 it says it cannot find files of that name although I have put 5 unique
e2e_ms_edd_nom_CCYYMMDD_HHMM.csv in the directory.

Code:
#
#
# Control the Unix processing cycle for uploading
# M+S Nomiated Delivery Days into the E2E database.
#
# 1.0  AM  13/09/2013  Initial Version
#
set +xv
 
# Execute the .profile (coz cron doesn't)
. ~/.profile
 
# Library functions
. $( dirname $0 )/common_functions.ksh
 
THIS=$( basename $0 )
 
fn_banner "Process M+S Nominated Delivery Days files"
 
echo "Starting: $(date)"
fn_writeTrace "starting"
 
 
# Local variables
bookmark="10"
TODAY=$(date "+%Y%m%d")
D_EXTTAB=/e2e_ms_xfer
MASK=e2e_ms_edd_nom*
D_WORK=$XFMSC
D_DONE=$XFMSZ
JOBNAME=$( echo $THIS | cut -f1 -d. )
 
 
fileCount=0
 
# Oracle
bookmark="20"
fn_oraenv
 
# Good to go
bookmark="30"
runControl=1
 
 while [ $runControl -eq 1 ]
 do
   cd $D_WORK
 
 
     # Are there any files?
    bookmark="35"
    fileFound=0
    ls -1 $MASK > /dev/null 2>&1
    if [ $? -eq 0 ]
    then
        # Oldest file
        bookmark="37"
        fileName=$( ls -1 $MASK | head -n 1 )
        mv filename e2e_ms_edd_nom.csv
 
        let fileCount=fileCount+1
        fileFound=1
 
       # Move the file to where the ext.tables expect
        bookmark="40"
        mv $XFMSC/e2e_ms_edd_nom.csv $XFMS
 
        # Invoke the Oracle process to upload the data
        #
        bookmark="50"
        fn_oraenv
        sqlplus $OCS @$SQL/exec_pull_nom_del_date.sql
 
        # Move the file to 'done'
        #
        bookmark="60"
        mv $XFMS/e2e_ms_edd_nom.csv $XFMSZ
       
     fi # file found
 
 
    fn_setHeartbeat $JOBNAME
 
done # while
 
# All done - Cleanup and exit
#
bookmark="70"
fn_cleanup
echo "Complete: $(date)"
fn_writeTrace "complete"
 
exit 0

LEARN ABOUT MINIX

rename

RENAME(2)							System Calls Manual							 RENAME(2)

NAME

       rename - change the name of a file

SYNOPSIS

       #include <stdio.h>

       int rename(const char *from, const char *to)

DESCRIPTION

       Rename  causes the link named from to be renamed as to.	If to exists, then it is first removed.  Both from and to must be of the same type
       (that is, both directories or both non-directories), and must reside on the same file system.

       Rename guarantees that an instance of to will always exist, even if the system should crash in the middle of the operation.

       If the final component of from is a symbolic link, the symbolic link is renamed, not the file or directory to which it points.

RETURN VALUE

       A 0 value is returned if the operation succeeds, otherwise rename returns -1 and the global variable errno indicates  the  reason  for  the
       failure.

ERRORS

       Rename will fail and neither of the argument files will be affected if any of the following are true:

       [ENAMETOOLONG] A path name exceeds PATH_MAX characters.

       [ENOENT]       A component of the from path does not exist, or a path prefix of to does not exist.

       [EACCES]       A component of either path prefix denies search permission.

       [EACCES]       The requested link requires writing in a directory with a mode that denies write permission.

       [EPERM]	      The  directory  containing  from	is marked sticky, and neither the containing directory nor from are owned by the effective
		      user ID.

       [EPERM]	      The to file exists, the directory containing to is marked sticky, and neither the containing directory nor to are  owned	by
		      the effective user ID.

       [ELOOP]	      Too many symbolic links were encountered in translating either pathname.	(Minix-vmd)

       [ENOTDIR]      A component of either path prefix is not a directory.

       [ENOTDIR]      From is a directory, but to is not a directory.

       [EISDIR]       To is a directory, but from is not a directory.

       [EXDEV]	      The link named by to and the file named by from are on different logical devices (file systems).

       [ENOSPC]       The  directory  in which the entry for the new name is being placed cannot be extended because there is no space left on the
		      file system containing the directory.

       [EIO]	      An I/O error occurred while making or updating a directory entry.

       [EROFS]	      The requested link requires writing in a directory on a read-only file system.

       [EFAULT]       Path points outside the process's allocated address space.

       [EINVAL]       From is a parent directory of to, or an attempt is made to rename ``.'' or ``..''.

       [ENOTEMPTY]    To is a directory and is not empty.
