ftp -n pipe for error
 

I have the following korn shell program for SLES 9
ftp -n server.ppd.com <<EOF
user $1 $2

cd /fs/m/project/fis/
mget *
prompt

EOF

This is working. how do I collect an error?
If I have an error after cd /fs/m/project/fis/
because the path does not exist. Then how can I check.
I see that get the following code


550 /fs/m/project/fis/ : A file or directory in the path name does not exist.

The program continues and does not stop and I can't stop after the error.

fix the probelm
 

I fixed the problem by
./file >/tmp/log

log has the error iformation
