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
