gfal-copy: Copy files

NAME

gfal-copy - Copy files

SYNOPSIS

gfal-copy [ OPTION ]... SOURCE DEST1 [ DEST2 ... ]

DESCRIPTION

gfal-copy Copies files from source to destination(s). If several destinations are specified, the file will be copy in a chain: src -> dst1, dst1 -> dst2, ... If used in an interactive console, transfer information will be giving during the copy, which varies depending on the available information. This command can be used to upload local files to remote file systems and to register files in the file catalog (see examples).

OPTIONS

-h, --help

show help about the command.

-V, --version

output version information and exit.

-v, --verbose

verbose mode. Repeat up to 3 times for the most verbose mode.

-D, --definition

define properties for gfal2.

-C, --client-info

provide custom client-side information

-t, --timeout TIMEOUT

maximum time for the operation to terminate - default is 1800 seconds. This timeout is enforced by gfal2-util, so it applies to the overall operation. It should be greater or equal than --transfer-timeout.

-E, --cert CERT

user certificate

--key KEY

user private key

-4

Forces gfal2-util to use IPv4 addresses only

-6

Forces gfal2-util to use IPv6 addresses only

-f, --force

if destination file(s) cannot be overwritten, delete it and try again

-p, --parent

if the destination directory does not exist, create it

-n, --nbstreams NBSTREAMS

specify the maximum number of parallel streams to use for the copy

--tcp-buffersize TCP_BUFFERSIZE

specify the TCP buffersize

-s, --src-spacetoken SRC_SPACETOKEN

source spacetoken to use for the transfer

-S, --dst-spacetoken DST_SPACETOKEN

destination spacetoken to use for the transfer

-T, --transfer-timeout TRANSFER_TIMEOUT

timeout for the transfer operation. This timeout is enforced by each plugin, so it applies to the transfer operation only.

-K, --checksum CHECKSUM

checksum algorithm to use, or algorithm:value

--from-file FROM_FILE

read sources from a file

--just-copy

just do the copy and skip any preparation (i.e. checksum, overwrite, etc.)

EXAMPLES

Copy a file to srm://endpoint.cern.ch/path/group, preferring a protocol as specified in the configuration file:

gfal-copy file:///etc/group srm://endpoint.cern.ch/path/

You can specify directly a protocol, if you know that it is supported by the end point:

gfal-copy file:///tmp/test gsiftp://endpoint.cern.ch/path/test

Do a chained copy:

gfal-copy file:///tmp/test gsiftp://endpoint.cern.ch/path/test file:///tmp/test2

Registration of a file in the LFC:

gfal-copy file:///tmp/source gsiftp://endpoint.cern.ch/path/test lfc://lfc-host.cern.ch/lfn

FILES

/etc/gfal2.d/*

All configuration files in this directory affect the behavior of the underlying gfal2, in particular, the default choice of transfer protocols.
