NAME

Net::ParSCP - Secure transfer of files between clusters via SSH

SYNOPSIS

  # One liner: transfers 'file' to all 
  # the machines in cluster 'clu' but 'june'
  $ perl -MNet::ParSCP \
     -e 'parpush(sourcefile=>q{file}, destination=>q{clu-june:/tmp/})'

DESCRIPTION

Functions in this module are for the implementation of the script parpush.

parpush

The main function is parpush:

  ($okh, $pid) = parpush(
    configfile  => $configfile,
    destination => [ 'cluster1:/path1', 'cluster2:/path2' ],
    scp         => $scp,
    scpoptions  => $scpoptions,
    sourcefile  => $sourcefile,
  );

only sourcefile and destination are required. The other arguments are optional.

In a list context returns two hash references ($okh, $pid).

%$okh: Is a hash with keys the names of the machines considered during the connections. The value is true (1) if all the connections with the corresponding machine were closed succesfully, false otherwise.
%$pid: Is a hash with keys the names of the machines considered during the connection. The value is an anonymous list with the process identifiers of the connections (undef if the fork failed) to that machine.
