Shell Programming and Scripting

Hi, I'm currently stuck in this ftp problem. Normally I just type ftp at the command line, but now I have to implement it in a code.

Basically I have to transfer a .txt file from a server, let's say hkhpdv13 in the folder of /home/sap/ftp to another server hkhpdv15 in the folder /home/sap/ftp/text

I've researched and saw this sample code.

#!/bin/sh
HOST='ftp.users.qwest.net'
USER='yourid'
PASSWD='yourpw'
FILE='file.txt'

ftp -n $HOST <<END_SCRIPT
quote USER $USER
quote PASS $PASSWD
put $FILE
quit
END_SCRIPT
exit 0

I don't really know where they get the END_SCRIPT, and also how they transferred to another server there. Help in explaining please?

I want to know how to transfer a file if it switches from one server to another. As well as how do I know if the file transfer was successful or not, is there a code in there? or something any help would be appreciated.

Your script looks good to me.

Code:

ftp -n $HOST <<END_SCRIPT
quote USER $USER
quote PASS $PASSWD
put $FILE
quit
END_SCRIPT

Don't confuse with END_SCRIPT , as its just a eof corresponding to the previous <<END_SCRIPT entry in the "ftp -n .." line. You can use any tag.
Since you are doing "put $FILE", the file will be transferred(put to the remote $HOST) provided the ftp connection is proper(ftp credentials) and $FILE is present in the dir from where you are running this script. Hope this helps.

I want to know how to switch servers?

Since I would be placing this script in a program. The script would have to log on to said server, enter username and pass, go to directory get the file and log on to another server, enter username and pass, go to that directory and paste the file?
