Question Copy multiple .txt files from one server to another server

SmilieHi all,
I have two servers : server A and server B
Weekly wise i use to receive files to server A to one particular location say /source/location . NOTE: In this location there will be other files also present other than these weekly arrival 18 files.
My task :
Quote:
1)Login to server B
2)Go to a location say /target/location/ and create a folder like 20150913(yyyymmdd)
2) Move only the 18 files from /target/location/ (files already copied from server A) to the folder that was created now-20150913. NOTE: Here also other than the required 18 files other files also will be present but we need to move only these 18 files to the newly created folder.
3) Then ftp to Server A to get the arrived 18 file from the location /source/location to /target/location using GET command
4)bye. to close the ftp connection once all the 18 files from Server A copied to Server B location(/target/location) is done
i need a shell script to perform this automatically every Thursday @ 3.00 PM EST. I need to send out success or failure email also after the process is done.

Either single script to perform all at once means moving files to folder in server B and getting files from server A or 2 different script like one for moving files to folder in server B and another script to get files from server A

Anything is fine for me. Please give me an idea or sample similar script with good explanation is required as am very new to shell scripting

This is not a homework. This is the usual work that i use to perform every week so one of my friend suggested to automate the process to save time to spend on other works as am fully engaged. here is the one that i tried am not sure whether its correct or not i just gave a try as am very new to the shell programming and UNIX environment. 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.

Hi Don First of thank you for your reply.
you have mentioned
Code:
mget [A-R].txt

which indicates can select multiple fiels. As i have mentioned, in the source directory i have additional files apart from A-R.txt so as you mentioned should i need to give the command as like
Code:
mget A.txt B.txt to R.txt 
               or
      mget A,B,..R.txt
