Module copyfrom
source code
copyfrom [-Crpx] FILES LOCAL_DIR
Copies FILES from each node of a cluster to
LOCAL_DIR. The cluster is identified using remote execution
syntax, for example:
osh @fred [ copyfrom /var/log/messages . ]
FILES identifies files on nodes of the cluster. It must
be an absolute path, (i.e. must begin with '/') and may
specify multiple files, e.g. /foo/bar*/*.[0-9].
LOCAL_DIR is a directory on the node from which the command
is being issued.
copyfrom will normally populate a directory under
LOCAL_DIR for each node in the cluster, creating the
subdirectories if necessary. The name of the subdirectory will be the
same as the node's name, specified in .oshrc. But if
-x is specified, then subdirectories will not be populated;
files will be placed directly in LOCAL_DIR. The
-x option is supported only for single-node clusters.
copyfrom is implemented using scp, and the
following scp flags are supported:
-
-C: enable compression.
-
-r: recursive copy
-
-p: preserve modification times, access times, and
modes.

Copies files from each node of the specified
cluster to local_dir. If
no_subdirs is False, then a subdirectory under
local_dir is created for each node of the cluster and the
files from a node are copied to that node's subdirectory. If
no_subdirs is true, then cluster must be a
single-node cluster, no subdirectory is created, and files are copied
directly into local_dir. Compression is used for copying if
compress is True. Directories are copied recursively if
recursive is True. File attributes are preserved if
preserve is True.
