FTP check if file exists and log it


I need to create a script that checks if a file exists on an offsite server
which only has ftp enabled. I was originally going to use perls Net::FTP
class but the client does not have perl installed nor wants it.

So, I have to use a shell script which logs into the server, then
checks if different files exist in multiple directories.

Basically, all I need to do is check if the file exists in these directories
but redirect output to a log file which I could bring back to my main
server for further processing.

Here's what I have so far:


( echo "user ${FtpUser} ${FtpPswd}
ls $FTPFile1
ls $FTPFile2
bye" ) | ftp -n ${HostName}

1. How can i capture the output of ls to a file either on the remote or
current server? and (this script will be placed in root's crontab)

2. Can I place the FTPFile{n} variable assignments into another file,
and use a while statement to read the lines 1 by 1 ... without having
to close the connection each time?

Hope I've explained this clearly.

Thank you!

Stupid me ... I figured i could just redirect the ftp output to
the local machine at the end of my ftp command.

But, can anyone help me with my 2nd question?

The only FTP client that I know that can support ls is NcFTP.

Here is an example of the command line you may used :
