Copying multiple files with "If Then Else" logic
I need some suggestions on how to write the code to copy multiple files rather than duplicating the code multiple times.

Example: I have four files that need to go throught this logic in the same way. Do I have to duplicate this chunk of code four times or can I built the logic in the same set of code without copying and pasting the code four times with different file names?

Please advice...

This is what the code does for one file....

1) copies the file from one directory to another
2) Strips when the date part from the ll command and writes to the log
3) Counts the number of records in the file and writes to the log
4) If record count is less than 1, it exits with an error code

In step 3, I am not sure if cat is the most effective way to do a wc -l.

Code:
cp -f $FTP/fwsalrpt.textp $EXPORT

RC=$?

if [ $RC -eq 0 ]
then
   DAY=$(ll $FTP | awk '/fwsalrpt.textp/ {print $6 $7 substr($8,1,5)}' )
   echo "*** ftp file from $DAY "  >>  $LOG
   RECORDS=$(cat $FTP/fwsalrpt.textp |wc -l )
   echo '*** Number of ftp fwsalrpt.textp records = ' $RECORDS >> $LOG
   if [ $RECORDS -lt 1 ]
   then
      echo "*** No data in input file "  >>  $LOG
      echo "*** fwcsales.rplftp.job failed "  >> $LOG
      date >> $LOG
      exit 3
   fi
else
   echo "*** copy of IBM file aborted"  >> $LOG
   echo "*** exit = " $RC  >> $LOG
   echo "*** fwcsales.rplftp.job failed "  >> $LOG
   date >> $LOG
   exit 2
fi

Hammer & Screwdriver Why not hold four filenames in a separate file?
Make file_list contain:
file_to_do_1
file_to_do_2
file_to_do_3
file_to_do_4

Then, your program just needs an outer loop:

Code:
while read zf
  do
#put read filename into your program variable
  file_to_process="$zf"

  (program loop - your existing code)
done <file_list

Thanks Joey...

I did create a filename with the list of files that need to be copied...But I don't see much of a change in code because I am getting a count of records for each file and also using AWK to print the date part and then writing it to the log...

I am just trying to find an efficient way to write the code.

Code:
while read FILENAME
do
  cp -f ${FTP}/$FILENAME ${EXPORT}/${FILENAME}
  if [ $? -eq 0 ] 
  then
   DAY=$(ll $FTP | awk '/fwsalrpt.textp/ {print $6 $7 substr($8,1,5)}' )
   echo "*** FTP file from $DAY "  >>  $LOG
   RECORDS=$(cat $FTP/fwsalrpt.textp |wc -l )
   echo '*** Number of ftp fwsalrpt.textp records = ' $RECORDS >> $LOG
   if [ $RECORDS -lt 1 ]
   then
      echo "*** No data in input file "  >>  $LOG
      echo "*** nz.fwcsales.rplftp.job failed "  >> $LOG
      date >> $LOG
      exit 3
   fi
else
   echo "*** Copy of IBM file aborted"  >> $LOG
   echo "*** exit = " $RC  >> $LOG
   echo "*** nz.fwcsales.rplftp.job failed "  >> $LOG
   date >> $LOG
   exit 2
fi 

  cp -f ${FTP}/$FILENAME ${EXPORT}/${FILENAME}
  if [ $? -eq 0 ] 
  then
   DAY=$(ll $FTP | awk '/fwmslrpt.textp/ {print $6 $7 substr($8,1,5)}' )
   echo "*** FTP file from $DAY "  >>  $LOG
   RECORDS=$(cat $FTP/fwmsalrpt.textp |wc -l )
   echo '*** Number of ftp fwmsalrpt.textp records = ' $RECORDS >> $LOG
   if [ $RECORDS -lt 1 ]
   then
      echo "*** No data in input file "  >>  $LOG
      echo "*** nz.fwcsales.rplftp.job failed "  >> $LOG
      date >> $LOG
      exit 3
   fi
else
   echo "*** Copy of IBM file aborted"  >> $LOG
   echo "*** exit = " $RC  >> $LOG
   echo "*** nz.fwcsales.rplftp.job failed "  >> $LOG
   date >> $LOG
   exit 2
fi
done < {FTP}/fwcsales_filenames.txt
