1 SCP(1) OpenBSD Reference Manual SCP(1)
4 scp - secure copy (remote file copy program)
7 scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
8 [-l limit] [-o ssh_option] [-P port] [-S program]
9 [[user@]host1:]file1 ... [[user@]host2:]file2
12 scp copies files between hosts on a network. It uses ssh(1) for data
13 transfer, and uses the same authentication and provides the same security
14 as ssh(1). Unlike rcp(1), scp will ask for passwords or passphrases if
15 they are needed for authentication.
17 File names may contain a user and host specification to indicate that the
18 file is to be copied to/from that host. Local file names can be made
19 explicit using absolute or relative pathnames to avoid scp treating file
20 names containing `:' as host specifiers. Copies between two remote hosts
23 The options are as follows:
25 -1 Forces scp to use protocol 1.
27 -2 Forces scp to use protocol 2.
29 -3 Copies between two remote hosts are transferred through the local
30 host. Without this option the data is copied directly between
31 the two remote hosts. Note that this option disables the
34 -4 Forces scp to use IPv4 addresses only.
36 -6 Forces scp to use IPv6 addresses only.
38 -B Selects batch mode (prevents asking for passwords or
41 -C Compression enable. Passes the -C flag to ssh(1) to enable
45 Selects the cipher to use for encrypting the data transfer. This
46 option is directly passed to ssh(1).
49 Specifies an alternative per-user configuration file for ssh.
50 This option is directly passed to ssh(1).
53 Selects the file from which the identity (private key) for public
54 key authentication is read. This option is directly passed to
58 Limits the used bandwidth, specified in Kbit/s.
61 Can be used to pass options to ssh in the format used in
62 ssh_config(5). This is useful for specifying options for which
63 there is no separate scp command-line flag. For full details of
64 the options listed below, and their possible values, see

96 NoHostAuthenticationForLocalhost

98 PasswordAuthentication

111 StrictHostKeyChecking
119 Specifies the port to connect to on the remote host. Note that
120 this option is written with a capital `P', because -p is already
121 reserved for preserving the times and modes of the file in
124 -p Preserves modification times, access times, and modes from the
127 -q Quiet mode: disables the progress meter as well as warning and
128 diagnostic messages from ssh(1).
130 -r Recursively copy entire directories. Note that scp follows
131 symbolic links encountered in the tree traversal.
134 Name of program to use for the encrypted connection. The program
135 must understand ssh(1) options.
137 -v Verbose mode. Causes scp and ssh(1) to print debugging messages
138 about their progress. This is helpful in debugging connection,
139 authentication, and configuration problems.
142 The scp utility exits 0 on success, and >0 if an error occurs.
145 rcp(1), sftp(1), ssh(1), ssh-add(1), ssh-agent(1), ssh-keygen(1),
146 ssh_config(5), sshd(8)
149 scp is based on the rcp(1) program in BSD source code from the Regents of
150 the University of California.
