11 (Linux) Copies one or more files to a group of hosts from a system.
12 Since the file contents to copy may be different for each host, a sepa‐
13 rate directory on this system is used for the source files for each
14 host. This can also be used in conjunction with opauploadall to upload
15 a host-specific configuration file, edit it for each host, and download
16 the new version to all the hosts.
17
18 NOTE: The tool opadownloadall can only copy from this system to a group
19 of hosts in the cluster. To copy files from hosts in the cluster to
20 this host, use opauploadall.

38 -f hostfile
39 Specifies the file with hosts in cluster. The default is
40 /etc/opa/hosts.
41
42
43 -d download_dir
44 Specifies the directory to download files from. The default
45 is downloads. If not specified, the environment variable
46 DOWNLOADS_DIR is used. If that is not exported, the default
47 is used.
48
49
50 -h HOSTS Specifies the list of hosts to download files to.
51
52
53 -u user Specifies the user to perform the copy. The default is the

63
64
65 source_file
66 Specifies the list of source files to copy from the system.
67
68
69 The option source_file is relative to download_dir/host‐
70 name. A local directory within download_dir/ must exist for
71 each host being downloaded to. Each downloaded file is copied
72 from download_dir/hostname/source_file.
73
74 dest_file Specifies the name of the file or directory on the destina‐
75 tion hosts to copy to.
76
77
78 If more than one source file is specified, dest_file is
79 treated as a directory name. The given directory must already
80 exist on the destination host. The copy fails for hosts where
81 the directory does not exist.
82
84 opadownloadall -h 'arwen elrond' irqbalance vncservers /etc
