opauploadall (8) - Linux Manuals

NAME

opauploadall

(Linux) Copies one or more files from a group of hosts to this system. Since the file name is the same on each host, a separate directory on this system is created for each host and the file is copied to it. This is a convenient way to upload log files or configuration files for review. This tool can also be used in conjunction with opadownloadall to upload a host specific configuration file, edit it for each host, and download the new version to all the hosts.

NOTE: To copy files from this host to hosts in the cluster, use opascpall or opadownloadall. user@ style syntax cannot be used when specifying filenames.

Syntax

opauploadall [-rp] [-f hostfile] [-d upload_dir] [-h 'hosts'] [-u user] source_file... dest_file

Options

--help

Produces full help text.

-p

Performs copy in parallel on all hosts.

-r

-f hostfile

File with hosts in cluster. Default is /etc/sysconfig/opa/hosts file.

-h hosts

List of hosts to upload from.

-u user

User to perform copy to. Default is current user code.

-d upload_dir

Directory to upload to. Default is uploads. If not specified, the environment variable UPLOADS_DIR is used. If that is not exported, the default, /uploads, is used.

 source_file 

Name of files to copy to this system, relative to the current directory. Multiple files may be listed.

 dest_file

Each uploaded file is copied to upload_dir/HOSTNAME/dest_file within the local system. If more than one source file is specified, dest_file is treated as a directory name.
