> Ftp With Exit Status, Ftp with exit status

Hi guys,

I'm wrinting a dropbox script for my client. I'm supposed to conenct to their server and get files everyday for processing and then delete the file off the server. The problem i face now is that the connection is not very stable.
To work around this I want to be able to build error checking into my script so that if the connection fails the script will run again and try to recconect. And also based on the exit status i will be able to know if i can delete the files off the server.
My ques is, how do I check the exit status for the script below. I'm open to the idea of using a different client like ncftp if required.

This if the connection method used by the client's side.

Code:

ftp -niv ftp.example.com
user user1 [prompts for password]
user anonymous@ftp.example.com
user user1 [prompts for password]

This is is the script i've written.

Code:

# Ftp
hostname="ftp.example.com"
username1="ftpuser"
username2="anonymous@ftp.example.com"
password1="xxxxxxx"
password2="example@example.com"

echo
echo ----------------------------------------------------------
echo Ftp script started at `date`
echo ----------------------------------------------------------
echo

cd $INBOX

ftp -inv $hostname << EOF

cd outgoing
pwd

mget *
bye
EOF

imho wget is sufficient in ftp, and has pretty good retry features for working on shady phonelines.. (; Maybe you could have wget try and download the files, retrying a few times, so you will most likely get complete files, and then your script initializes a normal ftp client to do the removing..

Just an idea..

I use expect for writing FTP scripts. It is very effective, and writing scripts is made very easy by the autoexpect script that comes with the distribution. It will capture inputs and outputs and put together a script that will mimic what you just did.
