FTP error codes

I have a Unix shell script which includes a call to FTP.

The code immediately following the call to FTP currently looks like
this:

if [ $? != 0 ]; then
echo "FTP script failed. Exiting with error."
exit 2
fi

However, I've been asked to modify this so that if the file isn't
there, we do not want to exit with an error code.

I suspect that the FTP script can fail for a variety of reasons - one
of which is that the file isn't there.

Is there one particular error code that specifically means "the file
isn't there"? Better yet, is there a list of all available error codes
for FTP? Thanks.

Ok, first off, the script snippet should never return an error, it will
only indicate if the ftp command worked or not.

for the ftpd error / success codes, check either "man ftpd" or
http://falcon.jmu.edu/cgi-bin/man-cgi?ftpd

in order to determine success/failure of the ftp session, you will need
to log the output of the session to a file and then examine the files
contents. Something along these lines:

ftp someserver > ftpdump.txt < get somefile
by
EOF

lcount=`grep 250 ftpdump.txt | wc -l`
mcount=`grep 550 ftpdump.txt | wc -l'
..
..
..

then if lcount is 0 and mcount is 1, the transfer failed due to missing
file. if lcount is 0 and mcount is 0, you had other issues
