This is just a part to get the files from source to target.

Code:
#!/bin/sh
HOST=source server(A)
echo "copying files from A server to B:/target/location"
'ftp -n $HOST >>END_SCRIPT
echo "connection success"
echo "logged on to A server"
cd /source/location
echo "source location log on success"
echo "starting the files transfer"
get A.txt
get B.txt
get C.txt
get D.txt
get E.txt
get F.txt
get G.txt
get H.txt
get I.txt
get J.txt
get K.txt
get L.txt
get M.txt
get N.txt
get O.txt
get P.txt
get Q.txt
get R.txt
echo "transfering of all 18 files done successfully"
bye
echo "Logged out of A server successfully"
END_SCRIPT'

EXIT_STATUS=$?
if[[ $EXIT_STATUS -eq 0 ]]
then
mailx -s\'"FTPing Files got failed"' kamegam@xxxx.com < $MSG/ftp_fail.msg
exit 1
else
mailx -s\'"FTPing Files are success"' kamegam@xxxx.com < $MSG/ftp_suc.msg
fi
exit 0

You seem to have a few problems:
  1. You can't mix ftp commands (e.g., get) and shell commands (e.g., echo) that way.
  2. Single quoting a command makes the shell think the entire single quoted string is the name of a command to execute.
  3. Iinstead of redirecting the output of the ftp command it looks like you want ftp to read the input from a here-document in your script.
  4. Using the ftp -n option tells ftp not to login to your destination host.
  5. Exit status 0 indicates success; not failure.
  6. You can't use a variable ([e.g., ICODE]$MSG[/ICODE]) before you assign a value to it. (Well, you can, but you'll get an empty string from the expansion.)
Assuming that you are logged into Server B when you run this code and that /bin/sh on your system is not a pure Bourne shell (which does not recognize [[ expression ]], maybe something more like:
Code:
#!/bin/sh
# Note that "HOST=source server(A)" only works if there are no space or ()s after the "=".
HOST="serverA"

echo "copying files from A server to B:/target/location"
ftp $HOST <<-END_SCRIPT
	verbose
	cd /source/location
	lcd /target/location
	mget [A-R].txt
	bye
END_SCRIPT
EXIT_STATUS=$?
echo "Logged out of A server with exit code $EXIT_STATUS"

if [[ $EXIT_STATUS -ne 0 ]]
then	mailx -s "FTPing Files got failed" kamegam@xxxx.com < /path/to/ftp_fail.msg
	exit 1
else	mailx -s "FTPing Files are success" kamegam@xxxx.com < /path/to/ftp_suc.msg
fi
exit 0

would work better, but this is completely untested.
