scp — OpenSSH secure file copy

POUŽITͶ

scp [-346ABCOpqRrsTv] [-c cipher] [-D sftp_server_path] [-F ssh_config] [-i identity_file] [-J destination] [-l limit] [-o ssh_option] [-P port] [-S program] source ... target

POPIS¶

scp copies files between hosts on a network.

It uses ssh(1) for data transfer, and uses the same authentication and provides the same security as a login session.

scp will ask for passwords or passphrases if they are needed for authentication.

The source and target may be specified as a local pathname, a remote host with optional path in the form [user@]host:[path], or a URI in the form scp://[user@]host[:port][/path]. Local file names can be made explicit using absolute or relative pathnames to avoid scp treating file names containing ‘:’ as host specifiers.

When copying between two remote hosts, if the URI format is used, a port cannot be specified on the target if the -R option is used.

Povolené jsou následující volby:

-3

Copies between two remote hosts are transferred through the local host. Without this option the data is copied directly between the two remote hosts. Note that, when using the legacy SCP protocol (via the -O flag), this option selects batch mode for the second host as scp cannot ask for passwords or passphrases for both hosts. This mode is the default.

-4

Vnutí scp použití IPv4 adresy.

-6

Vnutí scp použití IPv6 adresy.

-A

Allows forwarding of ssh-agent(1) to the remote system. The default is not to forward an authentication agent.

-B

Bude pracovat v dávkovém režimu (nebude se ptát na přihlašovací ani přístupová hesla).

-C

Povolí kompresi. Předá programu ssh(1) volbu -C pro povolení komprese.

-c šifra

Udává druh šifry, která má být použita pro šifrování přenosu dat. Tato volba je přímo předávána programu ssh(1).

-D sftp_server_path

When using the SFTP protocol support via -M, connect directly to a local SFTP server program rather than a remote one via ssh(1). This option may be useful in debugging the client and server.

-F ssh_config

Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1).

-i soubor_s_identitou

Selects the file from which the identity (private key) for public key authentication is read. This option is directly passed to ssh(1).

-J destination

Connect to the target host by first making an scp connection to the jump host described by destination and then establishing a TCP forwarding to the ultimate destination from there. Multiple jump hops may be specified separated by comma characters. This is a shortcut to specify a ProxyJump configuration directive. This option is directly passed to ssh(1).

-l limit

Limits the used bandwidth, specified in Kbit/s.

-O

Use the legacy SCP protocol for file transfers instead of the SFTP protocol. Forcing the use of the SCP protocol may be necessary for servers that do not implement SFTP, for backwards-compatibility for particular filename wildcard patterns and for expanding paths with a ‘~’ prefix for older SFTP servers.

-o ssh_volba

Může být použito pro předání voleb programu ssh ve formátu, který používá ssh_config(5). To se hodí pro použití voleb, pro něž v programu scp neexistuje vlastní volba. Úplné informace o níže uvedených volbách a jejich možných hodnotách jsou uvedeny v ssh_config(5).

-P port

Specifies the port to connect to on the remote host. Note that this option is written with a capital ‘P’, because -p is already reserved for preserving the times and mode bits of the file.

-p

Preserves modification times, access times, and file mode bits from the source file.

-q

Quiet mode: disables the progress meter as well as warning and diagnostic messages from ssh(1).

-R

Copies between two remote hosts are performed by connecting to the origin host and executing scp there. This requires that scp running on the origin host can authenticate to the destination host without requiring a password.

-r

Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal.

-S program

Určuje cestu k programu, který bude použit pro šifrované spojení. Program musí rozumět volbám ssh(1.)

-T

Disable strict filename checking. By default when copying files from a remote host to a local directory scp checks that the received filenames match those requested on the command-line to prevent the remote end from sending unexpected or unwanted files. Because of differences in how various operating systems and shells interpret filename wildcards, these checks may cause wanted files to be rejected. This option disables these checks at the expense of fully trusting that the server will not send unexpected filenames.

-v

Upovídaný režim. Zajistí, že příkazy scp a ssh(1) budou vypisovat ladící zprávy. Užitečné pro ladící účely při problémech se spojením, autentizací a konfigurací.

NÁVRATOVÁ HODNOTA¶

The scp utility exits 0 on success, and >0 if an error occurs.

HISTORIE¶

scp is based on the rcp program in BSD source code from the Regents of the University of California.

Since OpenSSH 9.0, scp has used the SFTP protocol for transfers by default.

NÁSTRAHY¶

The legacy SCP protocol (selected by the -O flag) requires execution of the remote user's shell to perform glob(3) pattern matching. This requires careful quoting of any characters that have special meaning to the remote shell, such as quote characters.
