scpg3

scpg3 — Secure Shell file copy client - Generation 3

Synopsis

scpg3 [options...]
[[user@] host [#port]:]file...
[[user@] host [#port]:]file_or_dir

Description

scpg3 (sshg3.exe on Windows) is used to securely copy files over the network. scpg3 launches ssh-broker-g3 to provide a secure transport using the Secure Shell version 2 protocol. ssh-broker-g3 will ask for passwords or passphrases if they are needed for authentication. scpg3 uses the configuration specified in the ssh-broker-config.xml file.

Any filename may contain a host, user, and port specification to indicate that the file is to be copied to or from that host. Copies between two remote hosts are permitted. The remote host(s) must be running a Secure Shell version 2 server with the sftp-server subsystem enabled.

The host parameter can optionally be enclosed in square brackets ([]) to allow the use of semicolons. The file argument can contain simple wild cards: asterisk (*) for any number of characters and question mark (?) for any one character.

Options

The following command-line parameters can be used to further specify the scpg3 options.

-d

Forces target to be a directory.

-q

Uses quiet mode (only fatal errors are shown).

-Q

Does not show progress indicator.

-p

Preserves file attributes and timestamps.

-u, --unlink-source

Removes source files after copying (file move).

-B, --batch-mode

Uses batch mode.

-I, --interactive

Prompts whether to overwrite an existing destination file (does not work with -B).

--overwrite [={yes|no}]

Decides whether to overwrite existing destination file(s) (default: yes).

-r

Recurses subdirectories.

--checksum[=yes|no|md5|sha1|md5-force|sha1-force|checkpoint]

Uses MD5 or SHA-1 checksums or a separate checkpoint database to determine the point in the file where file transfer can be resumed. Files smaller than buffer_size are not checked. Use md5-force or sha1-force with small files (default: yes, i.e. use MD5 checksums).

-W, --whole-file

Does not try incremental checks (default: no, i.e. try incremental checks).

--checkpoint=s<seconds>

Time interval between checkpoint updates (default: 10 seconds).

--checkpoint=b<bytes>

Byte interval between checkpoint updates (default: 10 MB).

--streaming[=yes|no|force]

Uses streaming in file transfer, if server supports it. Files smaller than buffer_size are not transferred using streaming. Use force with small files (default: yes).

-O, --offset=r<offset>|w<offset>|l<length>|t<length>

Sets offset. Offset r<offset> specifies the start offset in the source file. Offset w<offset> specifies the start offset in the destination file. Length l<length> specifies the amount of data to be copied. Truncate length t<length>, if given, specifies the length to which the destination file is truncated or expanded after the file data has been copied.

-a[arg]

Transfers files in ASCII mode. See manual page for description of optional argument.

--force-lower-case

Destination filename will be converted to lowercase characters.

--prefix=PREFIX

Adds prefix to filename during the file transfer. The prefix is removed after the file has been successfully transferred.

-P port

Connects to this Secure Shell port on the remote machine (default: 22).

-b buffer_size

Defines maximum buffer size for one request (default: 32768 bytes).

-N max_requests

Defines maximum number of requests sent in parallel (default: 10).

--fips

Uses the FIPS mode.

--plugin-path=PATH

Sets plugin path to PATH. This is only used in the FIPS mode.

--statistics=yes|no|simple

Chooses the statistics style (default: yes).

-V, --version

Displays version string and exits.

-h, --help

Displays help and exits.

Exit Values

scpg3 returns the following values based on the success of the operation:

0     Operation was successful. 
1     Internal error. 
2     Connection aborted by the user.
3     Destination is not a directory, but a directory was specified by the user. 
4     Connecting to the host failed. 
5     Connection lost. 
6     File does not exist. 
7     No permission to access file. 
8     Undetermined error from sshfilexfer. 
101   Wrong command-line arguments specified by the user. 

Examples

Copy files from your local system to a remote system:

$ scpg3 localfile user@remotehost:/dest/dir/for/file/

Copy files from a remote system to your local disk:

$ scpg3 user@remotehost:/dir/for/file/remotefile /dest/dir/for/file
