You could look at using tcl/tk to script the session, but it's a lot to learn if you have never used it before.

Hi,
I trap the return messages like this

ret=`ftp -n -v 2>&1 <<- END
open ${SERVER}
user ${USER} ${PASSWORD}
${TYPE}
lcd ${TO_DIR}
cd ${FROM_DIR}
get ${ORIGINAL_FILENAME} {NEW_FILENAME}
bye
END`

echo "$ret" | grep -q -i "incomplete"
if [[ $? -eq 0 ]]
then
echo "Ftp failed to get files"
exit 1
fi

echo "$ret" | grep -q -i "failed"
if [[ $? -eq 0 ]]
then
echo "Ftp failed to get files"
exit 1
fi

echo "$ret" | grep -q -i "No such"
if [[ $? -eq 0 ]]
then
echo "Ftp failed to get files"
exit 1
fi

echo "$ret" | grep -q -i "denied"
if [[ $? -eq 0 ]]
then
echo "Ftp failed to get files"
exit 1
fi

echo "$ret" | grep -q -i "refused"
if [[ $? -eq 0 ]]
then
echo "Ftp failed to get files"
exit 1
fi

echo "$ret" | grep -q -i "aborted"
if [[ $? -eq 0 ]]
then
echo "Ftp failed to get files"
exit 1
echo "$ret" | grep -q -i "cannot"
if [[ $? -eq 0 ]]
then
echo "Ftp failed to get files"
exit 1
fi

echo "$ret" | grep -q -i "Not connected"
if [[ $? -eq 0 ]]
then
echo "Ftp failed to get files"
exit 1
fi

You could also do:

yadda yadda yadda
put file
get file file.check
!

diff file file.check
if [ $? -ne 0 ]
then
error routine
fi

Try this work around

ftp -v server << EOF > /tmp/logfile 2>&1
cd directory
put file
bye
EOF
grep "Not Connected" /tmp/logfile|grep -v grep
if [ $? = 0 ]
then
echo "Error on ftp"
fi

It should work.

If you don't mind the overhead, you could add to your script:

get directory/file /tmp/diditwork

and then at the end of your script cksum the original and comapre that to the cksum of the temp file.

Hi Ted:

The 'ftp' session doesn't return an exit value denoting success or failure.

If you really want to decipher success/failure you can parse the three-digit numbers included with the reply from each 'ftp' command. Redirect the ftp session's verbose output into a logfile and parse the replies. The man pages (1M) for 'ftpd' [the daemon] discusss the reply format. Essentially, the first digit of the message indicates whether the reply is good, bad, or incomplete.

Regards!

Hi (again) Ted:

One more comment. When analyzing ftp's replies, the format consists of a three-digit number, a space, some text, and an end-of-line.

The numbers are standard. The text will vary operating system to operating system. Hence is is safer to parse and analyze the 3-digit number in the reply.
