copy files

Description

Usage

arccp [OPTION...] source destination

The arccp command copies files to, from and between grid storage elements.

Options

-h,  --help

Show help options

-p,  --passive

use passive transfer (off by default if secure is on, on by default if secure is not requested)

-n,  --nopassive

do not try to force passive transfer

-f,  --force

force overwrite of existing destination

-i,  --indicate

show progress indicator

-T,  --notransfer

do not transfer, but register source into destination. destination must be a meta-url.

-u,  --secure

use secure transfer (insecure by default)

-y,  --cache=path

path to local cache (use to put file into cache)

-r,  --recursive

operate recursively

-D,  --depth=level

operate recursively up to specified level

-R,  --retries=number

number of retries before failing file transfer

-L,  --location=URL

physical location to write to when destination is an indexing service. Must be specified for indexing services which do not automatically generate physical locations. Can be specified multiple times - locations will be tried in order until one succeeds.

-3,  --thirdparty

perform third party transfer, where the destination pulls from the source (only available with GFAL plugin)

-P,  --listplugins

list the available plugins (protocols supported)

-t,  --timeout=seconds

timeout in seconds (default 20)

-z,  --conffile=filename

configuration file (default ~/.arc/client.conf)

--no-authentication

do not perform any authentication for opened connections

--x509-authentication

perform X.509 authentication for opened connections

--token-authentication

perform token authentication for opened connections

--systemca

force using CA certificates configuration provided by OpenSSL

--gridca

force using CA certificates configuration for Grid services (typically IGTF)

--allowinsecureconnection

allow TLS connection which failed verification

-d,  --debug=debuglevel

FATAL, ERROR, WARNING, INFO, VERBOSE or DEBUG

-v,  --version

print version information

Extended Description

The arccp command copies files to, from and between grid storage elements. It can also be used to register files in file index catalogues, either automatically as the result of a file transfer, or by using the --notransfer option. For more information on ARC URL syntax please read "Protocols, Uniform Resource Locators (URL) and Extensions Supported in ARC" [NORDUGRID-TECH-7].

If source and/or destination start from '@', the remaining argument is assumed to be a path to a local file containing a list of URLs, one per line. In this case arccp performs like it were called multiple times - once for every URL.

When copying directories both the source and destination must end with the directory separator character and a recursion option -r or -D must be specified.

All data transfer goes through the machine of the caller of arccp, even in the case of two remote endpoints, unless the --thirdparty option is used. With this option credentials are delegated to the destination and it pulls the data directly from the source. The timeout option in this case applies to the entire transfer itself and default timeouts are used for connections to the remote endpoints. Note that third-party transfer is only possible if the GFAL2 plugin is installed.

Depending on the installed libraries (check with -P ), the following protocols may be used: file  (file://  prefix  may  be omitted), http, https, httpg, ftp, gsiftp, srm, root. To connect  source or destination to standard input/output use '-' instead of URL.

Environment Variables

X509_USER_PROXY

The location of the user's Grid proxy file. Shouldn't be set unless the proxy is in a non-standard location.

ARC_LOCATION

The location where ARC is installed can be specified by this variable. If not specified the install location will be determined from the path to the command being executed, and if this fails a WARNING will be given stating the location which will be used.

ARC_PLUGIN_PATH

The location of ARC plugins can be specified by this variable. Multiple locations can be specified by separating them by : (; in Windows). The default location is $ARC_LOCATION/lib/arc (\ in Windows).

Example

arccp -i gsiftp://example.com/grid/file1.dat /tmp/file1.dat

Files

~/.arc/client.conf

Some options can be given default values by specifying them in the ARC client configuration file. By using the --conffile option a different configuration file can be used than the default.
