-
-r -

-
-p -

-
-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

-
-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.
Examples
opadownloadall -h 'arwen elrond' irqbalance vncservers /etc
