How to write a script to FTP

Narasimham — Thu, 17 Jan 2002 20:48:54 GMT

I am working on HP-UX 9000/800 servers.

How to write a script to FTP a file from
1> one server to another server in same network
and
2> To a NT desktop (different network).
Anybody can send a sample file for the script.

Thanks in advance

Hi:

Here are two scripts:

#!/usr/bin/sh
ftp -n << EOF
verbose
open thehost
user uuu ppp
get /tmp/stuff
close
EOF

...

#!/usr/bin/sh
{ echo "open thehost
user uuu ppp
hash
mput *
close"
} | ftp -i -n -v 2>&1 | tee /tmp/ftplog.$$

Regards!

HI:

In the past, I used to do this stuff in the shell but now I NEVER do because I have found a much cleaner way to do it that makes error trapping duck soup. Do this stuff in Perl using the Net::FTP module which is available from http://www.cpan.org .

Here's how simple it can be:

#!/usr/bin/perl -w

use Net::FTP;
use strict;

my $ftp = Net::FTP->new("remotehost",Debug => 0);
$ftp->login("cstephen","top_secret");
$ftp->cwd("/tmp");
$ftp->get("myfile");
my $stat = $ftp->status;
my $full_stat = $ftp->code;
# $stat contains the first digit; usually all
# that you need to do is test if it is equal
# to 2. $full_stat contains the full 3-digit
# value but is seldom needed
printf("Status: %d Full Status: %d\n",$stat,$full_stat);
# Sample Test
if ($stat == 2)
{
print "Get was good\n";
}
else
{
print "Get was bad\n";
}
$ftp->quit;

I think if you start using this module you will never go back to shell scripting FTP. Moreover, these same scripts will run in the NT world. You can download a free version of perl for windows at http://www.activeperl.com.
Note that the answer is now the same on UNIX and NT and on the same subnet or across the net.

Notice that this method easily handles the error checking. If you like, you can use the shell for most of your script and simply use a bit a perl for the actual FTP transfers. In that case add the statement exit($stat) to the perl script and then your shell script does have a valid status indication.

You can also use a tool called expect. It is a tool for automating interactive applications such as telnet, ftp, passwd, fsck, rlogin, tip, etc. It can create scripts for you using autoexpect. You can find the package at http://expect.nist.gov/.

Hi again:

The scripts already offered should work for Unix to NT. The key issue is transfer your text files in ASCII mode. In this fashion, Unix "newlines" are automatically translated to Windows/DOS linefeed/carriage-return pairs, or vice versa in the opposite direction.

Hi:

If you are going to transfer to a Windows box then you must have an FTP server service running on the NT side. This is not a standard product but there are packages available. However, if you turn the question around and let the Windows box serve as a client to transfer the file then all you need is the above Perl script. This way the same script works for both platforms.

I use this method to transfer files from Unix to NT. Put a file called .netrc in the home directory of the user transfering files. Then put the following in that file :
machine "machine name" login "user" password "password"
(/home/user/.netrc with r-------- rights only chmod 400 .netrc)
Then the followind script will work
ftp hqmediware << EOF
put "file"
bye
EOF

It is on one line. If I have this
machine = NT1 (name in /etc/hosts or DNS or ..)
user = fred
password = 123456
Then I would put this in .netrc
machine NT1 login fred password 123456
