scp — secure copy (remote file copy program)


scp [-346BCpqrTv] [-c cipher] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-S program] [[user@]host1:]file1 ... [[user@]host2:]file2


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 ssh(1). scp will ask for passwords or passphrases if they are needed for authentication. File names may contain a user and host specification to indicate that the file is to be copied to/from that host. Local file names can be made explicit using absolute or relative pathnames to avoid scp treating file names containing ‘:’ as host specifiers. Copies between two remote hosts are also permitted. The options are as follows: -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 this option disables the progress meter. -4 Forces scp to use IPv4 addresses only. -6 Forces scp to use IPv6 addresses only. -B Selects batch mode (prevents asking for passwords or passphrases). -C Compression enable. Passes the -C flag to ssh(1) to enable compression. -c cipher Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1). -F ssh_config Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1). -i identity_file Selects the file from which the identity (private key) for public key authentication is read. This option is directly passed to ssh(1). -l limit Limits the used bandwidth, specified in Kbit/s. -o ssh_option Can be used to pass options to ssh in the format used in ssh_config(5). 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).

Note that this option is writ‐ ten with a capital ‘P’, because -p is already reserved for preserving the times and modes of the file. -p Preserves modification times, access times, and modes from the original file. -q Quiet mode: disables the progress meter as well as warning and diagnostic messages from ssh(1). -r Recursively copy entire directories. Note that scp follows symbolic links encoun‐ tered in the tree traversal. -S program Name of program to use for the encrypted connection. The program must understand ssh(1) options. -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 Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configura‐ tion problems.


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

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