The arccp command copies files to, from and between grid
storage elements.
arccp [options] source destination
- -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
- if the destination is an indexing service and not the same as the source
and the destination is already registered, then the copy is normally not
done. However, if this option is specified the source is assumed to be a
replica of the destination created in an uncontrolled way and the copy is
done like in case of replication. Using this option also skips validation
of completed transfers.
- -i,
--indicate
- show progress indicator. Using this option forces a check of the source
file before trying to transfer it, in order to find its size. Depending on
other information obtained about the source, there may be side-effects of
using this option, for example checksum verification or pre-staging data
from tape.
- -T,
--notransfer
- do not transfer, but register source into destination. destination must be
a meta-url. If destination already exists then meta-information of source
must match meta-information of destination. This can be overridden using
the --force option.
- -3, --thirdparty
- perform third party transfer, where the destination pulls from the source
(only available with GFAL plugin)
- -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 file 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.
- -P,
--listplugins
- list the available plugins (protocols supported)
- -t,
--timeout=seconds
- timeout in seconds (default 20). This timeout applies to connections to
remote services and indicates the maximum allowed idle time of the
transfer.
- -z,
--conffile=filename
- configuration file (default ~/.arc/client.conf)
- -d,
--debug=debuglevel
- FATAL, ERROR, WARNING, INFO, VERBOSE or DEBUG
- -v, --version
- print version information
- -?, --help
- print help
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.
- ~/.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.
- 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).
