NAME

Net::ParSCP - Parallel secure copy

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 only sub of interest 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 to hash references ($okh, $pid).

%$okh is a hash with keys the names of the machines considered during the connection. The value is true (1) if the connection was closed succesfully, false otherwise.

%$pid is a hash with keys the names of the machines considered during the connection. The value is the process identifier of the process that made the scp to that machine, undef if the fork failed.
