I have a conundrum best explained by the following items:

Cut from "man ncftpget":

DIAGNOSTICS
ncftpget returns the following exit values:

0 Success.

-------------------------------=<(*)>=--------------------------------

Snippet from "bak_website" script:

echo "bak_website: Now archiving http://mywebsite.com"
ncftpget -RV -u user -p passwd ftp://mywebsite.com .

# move and list the archived files
val=$?
if [ $val -eq 0 ]; then
mvarc
# moves files from dir n to dir n+1
else
echo "bak_website failed"
fi

bak_website: Now archiving http://mywebsite.com
ncftpget: server said: File successfully transferred
bak_website failed

-------------------------------=<(*)>=--------------------------------

On inspection I find the file was successfully transferred but mvarc
never executes. Shouldn't the message from the remote server set a
return code of zero? How can I capture ncftpget's return code?

echo "return code=$val"

You might try adding the -d option to ncftpget. It could be that one or
more files were transferred successfully but some were not, or the ftp
server is not a Unix server.

Good idea, Bill. I will try that tonight and post findings here.
There must
be some problem files causing an error return, because the server is
Unix.

Good suggestions, Bill. I added "echo "return code=$val"" and used "-
d ncftpget.log". The server is Linux, so that is not the problem.
The latest cron message has:

bak_website: Now archiving http://mywebsite.com
ncftpget: server said: File successfully transferred
return code=3
bak_website failed

The ncftpget.log file is 805954 bytes - ncftpget does a lot of
business! But grepping it for "error", "fail" and "warn" returns
nothing.

Could return code 3 be set by the server message, "File successfully
transferred" instead of by ncftpget?

Could you post a sample of that file, maybe the first or last 20
lines?

That should not happen. Maybe you could try changing http:// to ftp://.

Have you tried getting files manually one at a time to see if you get an
error? Or you might try a loop like this:

until ncftpget -R http://mywebsite.com; do sleep 60; done

By default, ncftpget should try to resume a failed transfer, but this
might be a waste of time if the transfer failed for reasons other than
a broken connection (e.g. permission problems, i/o errors or disk full).

The ncftpget command line does access "ftp://mywebsite.com" (see my
first post). The "http://" thing is just the echo line.

I've used get from plain ftp and also mirrored the entire site using
wget. Or did you mean: use ncftpget to get files one-at-a-time?

You really think it's an error then? I'm not sure. I get consistent
results every run, the total bytes downloaded increase just a little
each day, as you would expect. Also, the total bytes are just
slightly less than what I get with wget, which makes sense because
wget adds a ".listing" file to each directory.

But I'm not familiar with any of this stuff so I really appreciate
your . If you want the entire ncftp.log, I could email it to you.
