Recursive FTP -- here at last.

Over the past few weeks, I saw a couple of threads requesting recursive ftp:
Copying files between 2 Unix server
ftp from NT to UNIX

I decided to try to write a script to accommodate these requests. The result is HardFeed. Here are a few examples of what it can do.

HardFeed ftpserver joeblow somedir
This will connect to "ftpserver" and the user "joeblow". It will cd to "somedir". It will look at all of the files (and only the files) there. Each remote file that does not exist in the current directory will be copied to the current directory.

HardFeed -ds ftpserver joeblow somedir
This will work as the above example did. Except now we try to create local copies of any symbolic links or directories that we found in "somedir". Again, though, we will not overwrite any pre-existing object.

HardFeed -rds ftpserver joeblow somedir
Now we will create copies of any remote directories and desend into them. This will copy an entire directory tree. (except that it continues to ignore special files, pipes, etc.)

HardFeed -rs ftpserver joeblow somedir
This is similiar, except we only desend into pre-existing directories. You can use this to copy part of a directory structure. Just pre-create the few directories that you want to copy.

HardFeed -rdsm ftpserver joeblow somedir
This will copy a directory tree, but this time it will try to duplicate the mode (permissions) on each remote object that is duplicated.

HardFeed -rdsf ftpserver joeblow somdir
The -f is "freshen". Again it copies a directory tree. But if we have a local file and a remote file, the timestamps are compared. The remote file will overwrite the the local file if the remote file was newer.

There is more, including support for microsoft ftp servers that has been lightly tested. See the script itself for more info.

SIMPLEFTP(1)						    InterNetNews Documentation						      SIMPLEFTP(1)

NAME

       simpleftp - Rudimentary FTP client

SYNOPSIS

       simpleftp url [...]

DESCRIPTION

       simpleftp is a Perl script that provides basic support for fetching files with FTP in a batch oriented fashion.	It takes one or more FTP
       URLs on the command line.  The file(s) will be retrieved from the remote server and placed in the current directory with the same basename
       as on the remote; e.g., <ftp://ftp.isc.org/pub/usenet/CONFIG/active.gz> is stored as active.gz in the current directory.

       The script properly understands usernames, passwords and ports specified as follows:

	   ftp://user:password@host:port/path/file

BUGS

       simpleftp is an extremely poor substitute for more complete programs like the freely available wget or ncftp utilities.	It was written
       only to provide elementary support in INN for non-interactive fetching of the files in <ftp://ftp.isc.org/pub/pgpcontrol/> or
       <ftp://ftp.isc.org/pub/usenet/CONFIG/> without requiring administrators to install yet another package.	Its shortcomings as a general
       purpose program are too numerous to mention, but one that stands out is that downloaded files by simpleftp override existing files with the
       same name in the local directory.

HISTORY

       Tossed off by David C Lawrence <tale@isc.org> for InterNetNews.	Rewritten to use "Net::FTP" by Julien Elie.
