| SCP(1) OpenBSD Reference Manual SCP(1) |
| |
| NAME |
| scp - secure copy (remote file copy program) |
| |
| SYNOPSIS |
| scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file] |
| [-l limit] [-o ssh_option] [-P port] [-S program] |
| [[user@]host1:]file1 ... [[user@]host2:]file2 |
| |
| DESCRIPTION |
| 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). Unlike rcp(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: |
| |
| -1 Forces scp to use protocol 1. |
| |
| -2 Forces scp to use protocol 2. |
| |
| -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). |

| |
| -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 modes of the file in |
| rcp(1). |
| |
| -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 encountered in the tree traversal. |
| |
| -S program |
| Name of program to use for the encrypted connection. The program |
| must understand ssh(1) options. |
| |
| -v Verbose mode. Causes scp and ssh(1) to print debugging messages |
| about their progress. 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. |
