# SCP(1) - man - phpman [SCP(1)](https://www.chedong.com/phpMan.php/man/SCP/1/markdown) BSD General Commands Manual [SCP(1)](https://www.chedong.com/phpMan.php/man/SCP/1/markdown) ## NAME **scp** — OpenSSH secure file copy ## SYNOPSIS **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_ ## DESCRIPTION **scp** copies files between hosts on a network. It uses [ssh(1)](https://www.chedong.com/phpMan.php/man/ssh/1/markdown) for data transfer, and uses the same authentication and provides the same secu‐ rity 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. The options are as follows: ### -3 option the data is copied directly between the two remote hosts. Note that, when using the original SCP protocol (the default), 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 ### -6 ### -A an authentication agent. ### -B ### -C -C ### -c Selects the cipher to use for encrypting the data transfer. This option is directly passed to [ssh(1)](https://www.chedong.com/phpMan.php/man/ssh/1/markdown). ### -D When using the SFTP protocol support via **-s**, connect directly to a local SFTP server program rather than a remote one via [ssh(1)](https://www.chedong.com/phpMan.php/man/ssh/1/markdown). This option may be useful in debugging the client and server. ### -F Specifies an alternative per-user configuration file for **ssh**. This option is directly passed to [ssh(1)](https://www.chedong.com/phpMan.php/man/ssh/1/markdown). ### -i Selects the file from which the identity (private key) for public key authentication is read. This option is directly passed to [ssh(1)](https://www.chedong.com/phpMan.php/man/ssh/1/markdown). ### -J 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)](https://www.chedong.com/phpMan.php/man/ssh/1/markdown). ### -l Limits the used bandwidth, specified in Kbit/s. ### -O 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. This mode is the default. ### -o Can be used to pass options to **ssh** in the format used in [ssh_config(5)](https://www.chedong.com/phpMan.php/man/sshconfig/5/markdown). This is useful for specifying options for which there is no separate **scp** command-line flag. For full details of the options listed below, and their possible values, see [ssh_config(5)](https://www.chedong.com/phpMan.php/man/sshconfig/5/markdown).

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 ### -q [ssh(1)](https://www.chedong.com/phpMan.php/man/ssh/1/markdown). ### -R cuting **scp** there. This requires that **scp** running on the origin host can authenticate to the destination host without requiring a password. ### -r in the tree traversal. ### -S Name of _program_ to use for the encrypted connection. The program must understand [ssh(1)](https://www.chedong.com/phpMan.php/man/ssh/1/markdown) options. ### -s ### -T 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. Be‐ cause 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 This is helpful in debugging connection, authentication, and configuration problems. ## EXIT STATUS The **scp** utility exits 0 on success, and >0 if an error occurs. ## SEE ALSO [sftp(1)](https://www.chedong.com/phpMan.php/man/sftp/1/markdown), [ssh(1)](https://www.chedong.com/phpMan.php/man/ssh/1/markdown), [ssh-add(1)](https://www.chedong.com/phpMan.php/man/ssh-add/1/markdown), [ssh-agent(1)](https://www.chedong.com/phpMan.php/man/ssh-agent/1/markdown), [ssh-keygen(1)](https://www.chedong.com/phpMan.php/man/ssh-keygen/1/markdown), [ssh_config(5)](https://www.chedong.com/phpMan.php/man/sshconfig/5/markdown), [sftp-server(8)](https://www.chedong.com/phpMan.php/man/sftp-server/8/markdown), [sshd(8)](https://www.chedong.com/phpMan.php/man/sshd/8/markdown) ## HISTORY **scp** is based on the rcp program in BSD source code from the Regents of the University of Cali‐ fornia. ## AUTHORS Timo Rinne <<_tri@iki.fi_>> Tatu Ylonen <<_ylo@cs.hut.fi_>> ## CAVEATS The original SCP protocol (used by default) requires execution of the remote user's shell to perform [glob(3)](https://www.chedong.com/phpMan.php/man/glob/3/markdown) pattern matching. This requires careful quoting of any characters that have special meaning to the remote shell, such as quote characters. BSD February 10, 2022 BSD
