globus-url-copy [options] SOURCE-URL DESTINATION-URL

The globus-url-copy program is a command line tool for multi-protocol data movement. It supports gsiftp:// (GridFTP), ftp://, http://, https://, sshftp:// and file:/// protocol specifiers in the URL.

-help,  -usage

Print help.

-versions

Print the versions of all modules that this program uses

-c,  -continue-on-error

Do not die after any errors. By default, program will exit after most errors.

-a,  -ascii

Convert the file to/from ASCII format to/from local file format

-b,  -binary

Do not apply any conversion to the files. default

-f FILENAME

Read a list of URL pairs from filename. Each line should contain sourceURL destURL. Enclose URLs with spaces in double quotes ("). Blank lines and lines beginning with # will be ignored.

-cd,  -create-dest

Create destination directory if needed.

-r

Copy files in subdirectories

-fast

Recommended when using GridFTP servers. Use MODE E for all data transfers, including reusing data channels between list and transfer operations.

-t SECONDS

Run the transfer for this number of seconds and then end. Useful for performance testing or forced restart loops.

-q,  -quiet

Suppress all output for successful operation.

-v,  -verbose

Display URLs being transferred

-vb,  -verbose-perf

During the transfer, display the number of bytes transferred and the transfer rate per second. Show URLs being transferred

-dbg,  -debugftp

Debug ftp connections. Prints control channel communication to stderr

-rst,  -restart

Restart failed ftp operations.

-rst-retries RETRIES

The maximum number of times to retry the operation before giving up on the transfer. Use 0 for infinite. Default is 5.

-rst-interval SECONDS

The interval in seconds to wait after a failure before retrying the transfer. Use 0 for an exponential backoff. Default is 0.

-rst-timeout SECONDS

Maximum time after a failure to keep retrying. Use 0 for no timeout. Default is 0.

-stall-timeout SECONDS, -st SECONDS

How long before cancelling/restarting a transfer with no data movement. Set to 0 to disable. Default is 600 seconds.

-df FILENAME, -dumpfile FILENAME

Path to a file where untransferred URLs will be saved for later restarting. Resulting file is the same format as the -f input file. If file exists, it will be read and all other URL input will be ignored.

-do FILENAME, -dump-only FILENAME

Perform no write operations on the destination. Instead, all files that would be transferred are enumerated and dumped to the specified file. Resulting file is the same format as the -f input file. Note: if you intend to use this file as input for a future transfer, the -create-dest option will be required if any destination directories do not already exist.

-rp,  -relative-paths

The path portion of ftp URLs will be interpreted as relative to the user’s starting directory on the server. By default, all paths are root-relative. When this flag is set, the path portion of the ftp URL must start with %2F if it designates a root-relative path.

-s SUBJECT, -subject SUBJECT

Use this subject to match with both the source and dest servers.

-ss SUBJECT, -source-subject SUBJECT

Use this subject to match with the source server

-ds SUBJECT, -dest-subject SUBJECT

Use this subject to match with the destination server.

-tcp-bs SIZE, -tcp-buffer-size SIZE

Specify the size (in bytes) of the buffer to be used by the underlying ftp data channels.

-bs block SIZE, -block-size block SIZE

Specify the size (in bytes) of the buffer to be used by the underlying transfer methods.

-p PARALLELISM, -parallel PARALLELISM

Specify the number of parallel data connections should be used.

-notpt,  -no-third-party-transfers

Turn third-party transfers off (on by default).

-nodcau,  -no-data-channel-authentication

Turn off data channel authentication for ftp transfers.

-dcsafe,  -data-channel-safe

Set data channel protection mode to SAFE

-dcpriv,  -data-channel-private

Warning

Despite having -dcpriv in its command line globus-url-copy will silently fall back to an unencryted data channel when connected to a server that does not support data channel encryption (e.g. dCache)!

-off,  -partial-offset

Offset for partial ftp file transfers, defaults to 0.

-len,  -partial-length

Length for partial ftp file transfers, used only for the source url, defaults the full file.

-list URL

List the files located at URL.

-stripe

Enable striped transfers on supported servers.

-striped-block-size,  -sbs

Set layout mode and block size for striped transfers. If not set, server defaults will be used. If set to 0, Partitioned mode will be used. If set to > 0, Blocked mode will be used, with this as the block size.

-ipv6

Use ipv6 when available (EXPERIMENTAL)

-udt

Use UDT, a reliable udp based transport protocol, for data transfers

-g2,  -gridftp2

-dcstack STACK, -data-channel-stack STACK

Set the XIO driver stack for the network on both the source and the destination. Both must be GridFTP servers. The stack should contain all network drivers to use, in the order specified from bottom to top (e.g. -dcstack tcp,gsi). If the gsi driver is not included in the stack and data channel authentication is enabled, it will be inserted above the transport driver in the stack.

-fsstack STACK, -file-system-stack STACK

Set the XIO driver stack for the disk on both the source and the destination. Both must be GridFTP servers. The stack should contain all file system drivers to use, in the order specified from bottom to top.

-src-dcstack STACK, -source-data-channel-stack STACK

Set the XIO driver stack for the network on the source GridFTP server. See -dcstack above for description of the STACK string.

-src-fsstack STACK, -source-file-system-stack STACK

Set the XIO driver stack for the disk on the source GridFTP server. See -fsstack above for description of the STACK string.

-dst-dcstack STACK, -dest-data-channel-stack STACK

Set the XIO driver stack for the network on the destination GridFTP server. See -dcstack above for description of the STACK string.

-dst-fsstack STACK, -dest-file-system-stack STACK

Set the credentials to use for both ftp connections.

-src-cred CRED-FILE, -sc CRED-FILE

Set the credentials to use for source ftp connections.

-dst-cred CRED-FILE, -dc CRED-FILE

Set the credentials to use for destination ftp connections.

-af FILENAME, -alias-file FILENAME

File with mapping of logical host aliases to lists of physical hosts. When used with multiple concurrent connections, each connection uses the next host in the list. Each line should either be an alias, noted with the @ symbol, or a hostname[:port]. Currently, only the aliases @source and @destination are valid, and they are used for every source or destination URL.

-sync

Only transfer files where the destination does not exist or differs from the source. -sync-level controls how to determine if files differ.

-sync-level number

Criteria for determining if files differ when performing a sync transfer. The default sync level is 2. The available levels are:

• Level 0 will only transfer if the destination does not exist.
• Level 1 will transfer if the size of the destination does not match the size of the source.
• Level 2 will transfer if the time stamp of the destination is older than the time stamp of the source.
• Level 3 will perform a checksum of the source and destination and transfer if the checksums do not match. The default algorithm used for this checksum is MD5, but other algorithms can be specified with the -algo parameter.

-checksum-alg CHECKSUM-ALGORITHM

Set the algorithm type to use for all checksum operations during the transfer.

-verify-checksum

Perform a checksum on the source and destination after each file transfer and compare the two. If they do not match, fail the transfer. The default algorithm used for this checksum is MD5, but other algorithms can be specified with the -checksum-alg parameter.

The following environment variables are recognized:

GLOBUS_HOSTNAME

Overrides client hostname communicated to the server

GLOBUS_DOMAIN_NAME

Overrides client domainname communicated to the server

GLOBUS_FTP_CLIENT_DATA_IP

Overwrites client IP address communicated to the server for the data connection. Used when the receiver is behind a NAT and should be configured to the external address of its gateway.

GLOBUS_FTP_CLIENT_SOURCE_PASV

Configures sender side (source) instead of receiver side (destination) to open a data port and establishes the data connection from the receiver to the sender. By default the data connection is established from sender to receiver, but if the receiver is behind a NAT this doesn’t work, because the receiver will communicate its own address instead of the external address of its gateway to the sender and its own address can’t be reached directly from the sender.
