xrdcopy(1) General Commands Manual xrdcopy(1) NAME xrdcp - copy files SYNOPSIS xrdcp [options] source destination options: [--cksum args] [--debug lvl] [--coerce] [--force] [--help] [--license] [--nopbar] [--posc] [--proxy ipaddr:port] [--recursive] [--retry time] [--server] [--silent] [--sources num] [--streams num] [--tpc [delegate] first|only] [--verbose] [--version] [--xrate rate] [--zip file] [--dynamic-src] [--infiles fn] [--parallel n] [--allow-http] [--xattr] [--notlsok] [--tlsnodata] [--tlsmetalink] [--zip-mtln-cksum] [--rm-bad-cksum] [--continue] [--xrate-threshold] [--retry-policy] legacy options: [-adler] [-DSparm string] [-DIparm number] [-md5] [-np] [-ODcgi] [-OScgi] [-x] DESCRIPTION The xrdcp utility copies one or more files from one location to an- other. The data source and destination may be a local or remote file or directory. Additionally, the data source may also reside on multiple servers. OPTIONS -C | --cksum type[:value|print|source] obtains the checksum of type (i.e. adler32, crc32, md5 or zcrc32) from the source, computes the checksum at the destination, and verifies that they are the same. If auto is chosen as the checksum type, xrdcp will try to automatically infer the right checksum type based on source/destination configuration, source file type (metalink, ZIP), and available checksum plug-ins. If a value is specified, it is used as the source checksum. When print is spec- ified, the checksum at the destination is printed but is not veri- fied. -d | --debug lvl debug level: 1 (low), 2 (medium), 3 (high) -F | --coerce ignores locking semantics on the destination file. This option may lead to file corruption if not properly used. -f | --force re-creates a file if it is already present. -h | --help displays usage information. -H | --license displays license terms and conditions. -N | --nopbar does not display the progress bar. -P | --posc requests POSC (persist-on-successful-close) processing to create a new file. Files are automatically deleted should they not be suc- cessfully closed. -D | --proxy proxyaddr:proxyport [NOT YET IMPLEMENTED] use proxyaddr:proxyport as a SOCKS4 proxy. Only numerical ad- dresses are supported. -r | --recursive recursively copy all files starting at the given source directory. --retry retry failed copy-jobs. --server runs as if in a server environment. Used only for server-side third party copy support. -s | --silent neither produces summary information nor displays the progress bar. -y | --sources num uses up to num sources to copy the file. -S | --streams num use num parallel data streams to do the transfer (the main stream is in this case not used to carry out the transfer). The maximum value is 15. The default is 0 (i.e., use only the control stream). --tpc [delegate] first|only 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 dele- gates 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. -v | --verbose displays summary output. -V | -version displays version information and immediately exits. -z | --zip file copy given file from a ZIP archive (same as xrdcl.unzip opaque info). -X | --xrate rate limits the copy speed to the specified rate. The rate may be qual- ified 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. -X | --xrate-threshold rate If the transfer rate drops below given threshold force the client to use different source or if no more sources are available fail the transfer. -Z | --dynamic-src file size may change during the copy -I | --infiles fn specifies the file that contains a list of input files --parallel n number of copy jobs to be run simultaneously --allow-http allow HTTP as source or destination protocol. Requires the Xrd- ClHttp client plugin --xattr preserve extended attributes --notlsok If server is too old to support TLS encryption fallback to unen- crypted communication. --tlsnodata In case of roots/xroots protocol, encrypt only the control stream and leave the data streams unencrypted. --tlsmetalink Treat all URLs in metalink as roots/xroots. --zip-mtln-cksum Use the checksum available in a metalink file even if a file is being extracted from a ZIP archive. --rm-bad-cksum Remove the target file if checksum verification failed (enables also POSC semantics). --continue Continue copying a file from the point where the previous copy was interrupted. LEGACY OPTIONS Legacy options are provided for backward compatibility. These are now deprecated and should be avoided. -adler equivalent to "--cksum adler32:source". -DIpname numberval set the internal parameter pname with the numeric value numberval. -DSpname stringval set the internal parameter pname with the string value stringval. -md5 equivalent to "--cksum md5:source". -np equivalent to "--nopbar". -ODcgi add cgi information cgi to any destination xrootd URL. You should specify the opaque information directly on the destination URL. -OScgi add cgi information cgi to any source xrootd URL. -x equivalent to "--sources 12". OPERANDS source a dash (i.e. -) indicating stanard in, a local file, a local di- rectory name suffixed by /, or an xrootd URL in the form of xroot://[user@]host[:port]/absolutepath The absolutepath can be a directory. destination a dash (i.e. -) indicating stanard out, a local file, a local di- rectory name suffixed by /, or an xrootd URL in the form xroot://[user@]host[:port]/absolutepath The absolutepath can be a directory. 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 Determines the amount 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 in- stead of stderr. XRD_LOGMASK Determines which diagnostics topics should be printed at all lev- els. 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 sep- arately by setting one or more of the following variables: XRD_LOGMASK_ERROR, XRD_LOGMASK_WARNING, XRD_LOGMASK_INFO, XRD_LOG- MASK_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 top- ics but "PollerMsg" are enabled. Available topics: AppMsg, UtilityMsg, FileMsg, PollerMsg, PostMas- terMsg, XRootDTransportMsg, TaskMgrMsg, XRootDMsg, FileSystemMsg, AsyncSockMsg, TlsMsg XRD_TLSDBGLVL Determine the debug level for the TLS component. Valid values are: OFF, CTX, SOK, SIO, ALL and OUT. The default value is OFF. XRD_PARALLELEVTLOOP The number of event loops (i.e. the number of threads handling re- quests). Default number is 10. XRD_READRECOVERY Determines if read recovery should be enabled or disabled (enabled by default). XRD_WRITERECOVERY Determines if write recovery should be enabled or disabled (en- abled by default). XRD_OPENRECOVERY Determines if open recovery should be enabled or disabled for mu- table (truncate or create) opens (enabled by default). XRD_CONNECTIONWINDOW (-DIConnectionWindow) A time window for the connection establishment. A connection fail- ure is declared if the connection is not established within the time window. If a connection failure happens earlier then another connection attempt will only be made at the beginning of the next window. XRD_CONNECTIONRETRY (-DIConnectionRetry) Number of connection attempts that should be made (number of available connection windows) before declaring a permanent fail- ure. XRD_REQUESTTIMEOUT (-DIRequestTimeout) Default value for the time after which an error is declared if it was impossible to get a response to a request.

XRD_SUBSTREAMSPERCHANNEL (-DISubStreamsPerChannel) Number of streams per session. XRD_TIMEOUTRESOLUTION (-DITimeoutResolution) Resolution for the timeout events. Ie. timeout events will be processed only every XRD_TIMEOUTRESOLUTION seconds. XRD_STREAMERRORWINDOW (-DIStreamErrorWindow) Time after which the permanent failure flags are cleared out and a new connection may be attempted if needed. XRD_RUNFORKHANDLER (-DIRunForkHandler) Determines whether the fork handlers should be enabled, making the API fork safe. XRD_REDIRECTLIMIT (-DIRedirectLimit) Maximum number of allowed redirections. XRD_NOTAUTHORIZEDRETRYLIMIT (-dNotAuthorizedRetryLimit) Maximum number of allowed retries at a meta-manager for not-autho- rized error. XRD_POLLERPREFERENCE (-DSPollerPreference) A comma separated list of poller implementations in order of pref- erence. The default is: built-in.

XRD_CPCHUNKSIZE (-DICPChunkSize) Size of a single data chunk handled by xrdcp. XRD_NETWORKSTACK (-DSNetworkStack) The network stack that the client should use to connect to the server. Possible values are: IPAuto - automatically detect which IP stack to use IPAll - use IPv6 stack (AF_INET6 sockets) and both IPv6 and IPv4 (mapped to IPv6) addresses IPv6 - use only IPv6 stack and addresses IPv4 - use only IPv4 stack (AF_INET sockets) and addresses IPv4Mapped6 - use IPv6 stack and mapped IPv4 addresses XRD_DATASERVERTTL (-DIDataServerTTL) Time period after which an idle connection to a data server should be closed. XRD_LOADBALANCERTTL (-DILoadBalancerTTL) Time period after which an idle connection to a manager or a load balancer should be closed.
