gfal-copy — Copy files


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


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).


-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


Forces gfal2-util to use IPv4 addresses only


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


Copy a file to srm://, preferring a protocol as specified in the configuration file:

gfal-copy file:///etc/group srm://

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

gfal-copy file:///tmp/test gsi

Do a chained copy:

gfal-copy file:///tmp/test gsi file:///tmp/test2

Registration of a file in the LFC:

gfal-copy file:///tmp/source gsi lfc://



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