NAME
Net::SCP::Expect - Wrapper for scp that allows passwords via Expect.
SYNOPSIS
Example 1 - uses login method, longhand scp:
"my $scpe = Net::SCP::Expect->new;"
"$scpe->login('user name', 'password');"
"$scpe->scp('file','host:/some/dir');"
.
Example 2 - uses constructor, shorthand scp:
"my $scpe = Net::SCP::Expect->new(host=>'host', user=>'user',
password=>'xxxx');"
"$scpe->scp('file','/some/dir'); # 'file' copied to 'host' at
'/some/dir'"
.
Example 3 - Copying from remote machine to local host
"my $scpe = Net::SCP::Expect->new(user=>'user',password=>'xxxx');"
"$scpe->scp('host:/some/dir/filename','newfilename');"
PREREQUISITES
Expect 1.14. May work with earlier versions, but was tested with 1.14
only.
DESCRIPTION
This module is simply a wrapper around the scp call. The primary
difference between this module and *Net::SCP* is that you may send a
password programmatically, instead of being forced to deal with
interactive sessions.
USAGE
Net::SCP::Expect->new(*option=>val*,...)
Creates a new object and optionally takes a series of options (see
below).
login(*login,password*)
If the login and password are not passed as options to the constructor,
they must be passed with this method. If they were already set, this
method will overwrite them with the new values. Failure to pass a login
or a password to this method will cause the program to croak.
scp(*source, host:destination*);
or
scp(*host:source, destination*);
or
scp(*source, destination*); # Same as scp(*source, host:destination*)
Copies the file from source to destination. If the host name is omitted
from this method, then it is assumed that you are copying from the local
machine to a remote destination on *host*. Of course, if you didn't
specify a host, then you are simply using scp as an expensive version of
cp.
To copy from a remote location to your local machine, you must use the
longhand form.
OPTIONS
cipher - Selects the cipher to use for encrypting the data transfer.
host - Specify the host name. This is only useful if you are copying
from the local machine to a remote machine, but NOT vice-versa.
password - The password for the given login.
port - Use the specified port.
preserve - Preserves modification times, access times, and modes from
the original file.
recursive - Set to 1 if you want to recursively copy entire directories.
timeout - Sets the timeout value for your operation. The default is 10
seconds.
user - The login name you wish to use.
verbose - Set to 1 if you want verbose output sent to STDOUT.
NOTES
The -q option (disable progress meter) is automatically passed to scp.
The -B option may NOT be set. If you don't want to send passwords, I
recommend using *Net::SCP* instead.
In the event that Ben Trott releases a version of *Net::SSH::Perl* that
supports scp, I recommend using that instead.
FUTURE PLANS
There are a few options I haven't implemented. If you *really* want to
see them added, let me know and I'll see what I can do.

THANKS
Thanks to Roland Giersig (and Austin Schutz) for the Expect module. Very
handy.
