i want to execute a shell script which transfers files from one server to another using ftp in unix. How can i check whether the ftp is successful or not.(i.e files are transferred to destination server). because if i am checking the return code of ftp, it always shows 0 (denoting ftp is success). but when i check the remote server , the files are not transferred. can any1 help me out.. my sample code for ftp is
ECHO="/bin/echo -e"
ftp -n $REMOTE_MC <<_FTP1
quote USER $REMOTE_UID
quote PASS $REMOTE_PWD
lcd $LOCAL_FOLDER
cd $REMOTE_FOLDER
prompt noprompt
binary
mput $LOCAL_FNAME
quit
_FTP1
RC=$?
$ECHO "RC = $RC"
if [ $RC -eq 0 ]; then
$ECHO "FTP successfull....."
else
$ECHO "FTP failed"
fi
fi
The binary ftp always returns 0 as itself has no functional errors. For errors regarding the file transfer, there are other codes, which can't be accessed via $? . They can only be parsed as text output from ftp.
Can you use something else like scp ? That might make it much easier as you can use $? again and would be encrypted ie. safer. It would need an exchange of a key though because it works password-less when being used non-interactive.
If there is no way of key exchange for authentication, you could still feed it with expect for example.
