Cron FTP get and delete
 

Hey everyone I need a little help here. I want to setup a cron that will do 3 things.
1) It will connect via ftp to a server and download a file called games.log
2) Then delete the source games.log from the ftp site after the download finished.
3) Then run this command line shell
php vsp.php -l wet "/public_html/wet/games.log"

Can someone please help me out with this?

Does it have to use FTP?

I ask because FTP is rather difficult to script as there is no way to control it via command line switches, it needs to be controlled interactively as if you were sitting there typing commands into it.

In contrast, if you could use some mountable network filesystem (NFS, SSH, etc) then you can mount the remote machine and operate on the files as if they were local.

Not to say doing it over FTP isn't possible, it will just be harder. I have certainly never been able to script the functionality I have wanted when using an interactive FTP client, at least.

You could call the ftp command like:

Call it like
ftp user:password@host << EOF
get games.log
del games.log
bye
EOF

Not really

/ftp ENTER
n
n
n
...

I d bet it can download from the ftp

The problem with this, at least in my experience, is that it works fine as long as everything goes according to plan. It is difficult to accurately catch and handle errors in this scenario since the script can't interact with the FTP client itself, and is just sending canned messages to it.

For example, if we could call an ftp client with commands like:

We could easily trap errors by checking the return value it gives back for each step; but when you just throw commands at the client, there is no way to tell were an error occurred so that it can be handled gracefully.

In man wget, I got this. This may maybe interest you.
