This is my final function. For 2000 records running in 3 minutes. Can this be tuned . Many Thanks in advance.

Code:
modify_customer_feed()
{
while IFS='' read line
do
f1="$(echo "$line" | cut -c1-18)"
f2="$(echo "$line" | cut -c19-27)"
f2=$(echo "$f2"|sed 's/ /0/g')
f2=$(echo "$f2"|sed 's/000000000/         /g')
f3="$(echo "$line" | cut -c28-686)"
f4="$(echo "$line" | cut -c687-702)"
f4=$(echo "$f4"|sed 's/ /0/g')
f4=$(echo "$f4"|sed 's/0000000000000000/                /g')

f5="$(echo "$line" | cut -c703-718)"
f5=$(echo "$f5"|sed 's/ /0/g')
f5=$(echo "$f5"|sed 's/0000000000000000/                /g')
f6="$(echo "$line" | cut -c719-854)"
printf "%s%s%s%s%s%s\n" "$f1" "$f2" "$f3" "$f4" "$f5" "$f6"
done < ${SOURCEFILE}    >  $id_final_file

if [[ $? -ne 0 ]]
then
  rm -f  $id_final_file
  return 1

  mv -f $id_final_file $SOURCEFILE

							TPM Management - tpm_takeownership

NAME

       tpm_takeownership - setup an owner on the TPM

SYNOPSIS

       tpm_takeownership [OPTION]

DESCRIPTION

       tpm_takeownership setup an owner on the system's TPM (via the TPM_TakeOwnership API).  This operation requires the TPM to be enabled and
       can be restricted by tpm_setownable.  The command will prompt for owner and SRK passwords and confirmations of these if executed without
       either of the -well-known options, otherwise, a secret of all zeros is set for the requested password.  After the second confirmation, be
       patient as the command may take awhile.

       -h, --help
	      Display command usage info.

       -v, --version
	      Display command version info.

       -l, --log [none|error|info|debug]
	      Set logging level.

       -u, --unicode
	      Use TSS UNICODE encoding for passwords to comply with applications using TSS popup boxes

       -y, --owner-well-known
	      Set a secret of all zeros (20 bytes of zeros) as the owner's secret.

       -z, --srk-well-known
	      Set a secret of all zeros (20 bytes of zeros) as the SRK secret.
