# opadownloadall(8)

## 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.
