.SH DESCRIPTION
The \fBxrdcp\fR utility copies one or more files from one location to
another. The data source and destination may be a local
or remote file or directory.  Additionally, the data source may also reside
on multiple servers.
.SH OPTIONS
\fB-C\fR | \fB--cksum\fR \fItype\fR[\fB:\fR\fIvalue\fR|\fIprint\fR|\fIsource\fR]
.RS 5
obtains the checksum of \fItype\fR (i.e. adler32, crc32, or md5) from the source,
computes the checksum at the destination, and verifies that they are the same. If a \fIvalue\fR
is specified, it is used as the source checksum. When \fIprint\fR
is specified, the checksum at the destination is printed but is \fInot\fR verified.

.RE
\fB-d\fR | \fB--debug\fR \fIlvl\fR
.RS 5
debug level: 1 (low), 2 (medium), 3 (high)

.RE
\fB-F\fR | \fB--coerce\fR
.RS 5
ignores locking semantics on the destination file. This option may lead to
file corruption if not properly used.

.RE
\fB-f\fR | \fB--force\fR
.RS 5
re-creates a file if it is already present.

.RE
\fB-h\fR | \fB--help\fR
.RS 5
displays usage information.

.RE
\fB-H\fR | \fB--license\fR
.RS 5
displays license terms and conditions.

.RE
\fB-N\fR | \fB--nopbar\fR
.RS 5
does not display the progress bar.

.RE
\fB-P\fR | \fB--posc\fR
.RS 5
requests POSC (persist-on-successful-close) processing
to create a new file. Files are automatically deleted should they not be
successfully closed.

.RE
\fB-D\fR | \fB--proxy\fR \fIproxyaddr\fB:\fIproxyport\fR
.RS 5
[NOT YET IMPLEMENTED]

use \fIproxyaddr\fB:\fIproxyport\fR as a SOCKS4 proxy. Only numerical addresses are supported.

.RE
\fB-r\fR | \fB--recursive\fR
.RS 5
recursively copy all files starting at the given source directory. This option is
\fIonly\fR supported for local files.

.RE
\fB--server\fR
.RS 5
runs as if in a server environment. Used only for server-side
third party copy support.

.RE
\fB-s\fR | \fB--silent\fR
.RS 5
neither produces summary information nor displays the progress bar.

.RE
\fB-y\fR | \fB--sources\fR \fInum\fR
.RS 5
[NOT YET IMPLEMENTED]

uses up to \fInum\fR sources to copy the file.

.RE
\fB-S\fR | \fB--streams\fR \fInum\fR
.RS 5
uses \fInum\fR additional parallel streams to do the transfer.
The maximum value is 15. The default is 0 (i.e., use only the main stream).

.RE
\fB--tpc\fR \fIfirst|only\fR
.RS 5
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 \fI'first'\fR tries tpc and if it fails, does a normal copy;
while \fI'only'\fR fails the copy unless tpc succeeds.

.RE
\fB-v\fR | \fB--verbose\fR
.RS 5
displays summary output.

.RE
\fB-V\fR | \fB-version\fR
.RS 5
displays version information and immediately exits.

.RE
\fB-z\fR | \fB--zip\fR
.RS 5
copy given file from a ZIP archive.

.RE
\fB-X\fR | \fB--xrate\fR \fIrate\fR
.RS 5
[NOT YET IMPLEMENTED]

limits the copy speed to the specified \fIrate\fB. The rate may be qualified
with the letter \fBk\fR, \fBm\fR, or \fBg\fR to indicate kilo, mega, or giga
bytes, respectively. The option only applies when the source or destination is
local.

.SH ENVIRONMENT
The following environment variables are supported. They apply to xrdfs and any
other application using the libXrdCl library, unless specified otherwise. The
text in the brackets is a name of the corresponding xrdcp commandline parameter.

XRD_LOGLEVEL
.RS 5
Detemines the amout of diagnostics that should be printed. Valid values are:
\fIDump\fR, \fIDebug\fR, \fIInfo\fR, \fIWarning\fR, and \fIError\fR.
.RE

XRD_LOGFILE
.RS 5
If set, the diagnostics will be printed to the specified file instead of stderr.
.RE

XRD_LOGMASK
.RS 5
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.
.br

The log mask may as well be handled for each diagnostic level separately by
setting one or more of the following variables: \fIXRD_LOGMASK_ERROR\fR,
\fIXRD_LOGMASK_WARNING\fR, \fIXRD_LOGMASK_INFO\fR, \fIXRD_LOGMASK_DEBUG\fR,
and \fIXRD_LOGMASK_DUMP\fR. The default for each level is "All", except
for the \fIDump\fR level, where the default is "All|^PollerMsg". This means
that, at the \fIDump\fR level, all the topics but "PollerMsg" are enabled.
