Fairly new to scripting
Hi, my team has existing ftp scripts that basically ftp files from one server to the other. Can anyone show me how to add some lines where if the ftp fails, an email could be sent out to myself and others on my team so that we are alerted? Thanks in advance.

Should look something like this

Code:
ftp -n ${HOST} << SCRIPT
user <username> <password>
binary
lcd ${WHERE_TO_SAVE}
cd ${WHERE_DOWNLOAD_FROM}
get ${WHICH_FILE_TO_GET}
quit
SCRIPT

if [ -f ${WHICH_FILE_TO_GET} ]
then
    echo "successful"
else
    echo "Failed: could not FTP"
    echo "Failed" | mailx -s "FTP failed for ${WHICH_FILE_TO_GET}" abc@xyz.com

fi

It is tough to get return codes from ftp put / get operations. There are ways, but I am not aware of them.

I would replace ftp with an scp ( Create the keys for an auto logon ). scp does give a good return code for you.

Thank you for the idea. From what I can tell basically this script would just check if the file in the location but not necessarily know if the file is complete, correct?

An astutue observation, and a condition known as partial failure. Alas FTP isn't really upto the job. SCP or SFTP would be better.

Unless you do an ftp "ls -l" of the file and decode it's length then compare that with the downloaded file.

Thanks, I have a feeling I'm going to like this place and rest assured I'll have more questions Smilie.

How does SCP work? And how can I apply it to my situation? Does 'mailx' work with this as well? Yes, I guess I'm asking for sample code to understand better.

1. scp - secure copy - man scp - basically -

Code:
scp [options] from to

2. mailx has nothing to do with scp, sftp or ftp.
