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

Environment Variables

The following environment variables are also used by this command:

HOSTS

List of hosts; used if -h option not supplied.

HOSTS_FILE

File containing list of hosts; used in absence of -f and -h.

FF_MAX_PARALLEL

When the -p option is used, the maximum concurrent operations are performed.

DOWNLOADS_DIR

Directory to download from, used in absence of -d.
