NAME

       opadownloadall

       (Linux)  Copies  one  or  more  files  to  a  group of hosts from a system. Since the file
       contents to copy may be different for each host, a separate directory on  this  system  is
       used  for  the  source  files  for  each  host.  This can also be used in conjunction with
       opauploadall to upload a host-specific configuration file, edit  it  for  each  host,  and
       download the new version to all the hosts.

       NOTE:  The  tool  opadownloadall can only copy from this system to a group of hosts in the
       cluster. To copy files from hosts in the cluster to this host, use opauploadall.

Syntax

       opadownloadall [-rp] [-f  hostfile] [-d  download_dir] [-h 'HOSTS']
       [-u  user] source_file ...  dest_file

Options

       --help

                 Produces full help text.

       -r

                 Performs recursive download of directories.

       -p

                 Performs copy in parallel on all hosts.

       -f hostfile

                 Specifies the file with hosts in cluster. Default is /etc/opa/hosts.

       -d download_dir

                 Specifies the directory to download files from. Default  is  downloads.  If  not
                 specified,  the  environment  variable  DOWNLOADS_DIR  is  used.  If that is not
                 exported, the default is used.

       -h HOSTS

                 Specifies the list of hosts to download files to.

       -u user

                 Specifies the user to perform the copy. Default is the current user code.

       NOTE: The user@ style syntax cannot be used in the arguments to opadownloadall.

       source_file

                 Specifies the list of source files to copy from the system.

                 The option  source_file is relative to  download_dir/hostname. A local directory
                 within  download_dir/  must  exist  for  each  host  being  downloaded  to. Each
                 downloaded file is copied from  download_dir/hostname/source_file.

       dest_file

                 Specifies the name of the file or directory on the destination hosts to copy to.

                 If more than one source file is specified, dest_file is treated as  a  directory
                 name.  The  given directory must already exist on the destination host. The copy
                 fails for hosts where the directory does not exist.

Example

       opadownloadall -h 'arwen elrond' irqbalance vncservers /etc

       # Copies two files to 2 hosts

       opadownloadall -p irqbalance vncservers /etc

       # Copies two files to all hosts
