-C | --cksum
type[:value|print|source]
obtains the checksum of
type (i.e. adler32, crc32,
or md5) from the source, computes the checksum at the destination, and
verifies that they are the same. If a
value is specified, it is used as
the source checksum. When
print is specified, the checksum at the
destination is printed but is
not verified.
debug level: 1 (low), 2 (medium), 3 (high)
ignores locking semantics on the destination file. This
option may lead to file corruption if not properly used.
re-creates a file if it is already present.
displays usage information.
displays license terms and conditions.
does not display the progress bar.
requests POSC (persist-on-successful-close) processing to
create a new file. Files are automatically deleted should they not be
successfully closed.
[NOT YET IMPLEMENTED]
use proxyaddr:proxyport as a SOCKS4 proxy.
Only numerical addresses are supported.
recursively copy all files starting at the given source
directory.
runs as if in a server environment. Used only for
server-side third party copy support.
neither produces summary information nor displays the
progress bar.
uses up to
num sources to copy the file.
uses
num additional parallel streams to do the
transfer. The maximum value is 15. The default is 0 (i.e., use only the main
stream).
copies the file from remote server to remote server using
third-party-copy protocol (i.e., data flows from server to server). The source
and destination servers must support third party copies. Additional security
restrictions may apply and may cause the copy to fail if they cannot be
satisfied. Argument '
first' tries tpc and if it fails, does a normal
copy; while '
only' fails the copy unless tpc succeeds. When
'
delegate' is specified, the copy delegates the command issuer's
credentials to the target server which uses those credentials to authenticate
with the source server. Delegation is ignored if the target server is not
configured to use delegated credentials. Currently, only gsi credentials can
be delegated.
displays version information and immediately exits.
copy given file from a ZIP archive (same as xrdcl.unzip
opaque info).
[NOT YET IMPLEMENTED]
limits the copy speed to the specified rate. The rate
may be qualified with the letter k, m, or g
to indicate kilo, mega, or giga bytes, respectively. The option only applies
when the source or destination is local.
file size may change during the copy
specifies the file that contains a list of input files
automatically create remote destination path
number of copy jobs to be run simultaneously
allow HTTP as source or destination protocol. Requires
the XrdClHttp client plugin
XRD_LOGLEVEL
Detemines the amout of diagnostics that should be
printed. Valid values are: Dump, Debug, Info,
Warning, and Error.
XRD_LOGFILE
If set, the diagnostics will be printed to the specified
file instead of stderr.
XRD_LOGMASK
Determines which diagnostics topics should be printed at
all levels. It's a "|" separated list of topics. The first element
may be "All" in which case all the topics are enabled and the
subsequent elements may turn them off, or "None" in which case all
the topics are disabled and the subsequent flags may turn them on. If the
topic name is prefixed with "^", then it means that the topic should
be disabled. If the topic name is not prefixed, then it means that the topic
should be enabled.
The log mask may as well be handled for each diagnostic level
separately by setting one or more of the following variables:
XRD_LOGMASK_ERROR, XRD_LOGMASK_WARNING,
XRD_LOGMASK_INFO, XRD_LOGMASK_DEBUG, and
XRD_LOGMASK_DUMP. The default for each level is "All",
except for the Dump level, where the default is
"All|^PollerMsg". This means that, at the Dump level, all
the topics but "PollerMsg" are enabled.
Available topics: AppMsg, UtilityMsg, FileMsg, PollerMsg,
PostMasterMsg, XRootDTransportMsg, TaskMgrMsg, XRootDMsg, FileSystemMsg,
AsyncSockMsg

for mutable (truncate or create) opens (enabled by default).
XRD_CONNECTIONWINDOW (-DIConnectionWindow)

declared if it was impossible to get a response to a request.

is declared (and a recovery attempted) if there are unfulfilled requests and
there is no socket activity or a registered wait timeout.
XRD_SUBSTREAMSPERCHANNEL (-DISubStreamsPerChannel)
Number of streams per session.
XRD_TIMEOUTRESOLUTION (-DITimeoutResolution)

out and a new connection may be attempted if needed.
XRD_RUNFORKHANDLER (-DIRunForkHandler)
