1 SCP(1) OpenBSD Reference Manual SCP(1)
4 scp - secure copy (remote file copy program)
7 scp [-1246BCpqrv] [-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 -4 Forces scp to use IPv4 addresses only.
31 -6 Forces scp to use IPv6 addresses only.
33 -B Selects batch mode (prevents asking for passwords or
36 -C Compression enable. Passes the -C flag to ssh(1) to enable
40 Selects the cipher to use for encrypting the data transfer. This
41 option is directly passed to ssh(1).
44 Specifies an alternative per-user configuration file for ssh.
45 This option is directly passed to ssh(1).
48 Selects the file from which the identity (private key) for public
49 key authentication is read. This option is directly passed to
53 Limits the used bandwidth, specified in Kbit/s.
56 Can be used to pass options to ssh in the format used in
57 ssh_config(5). This is useful for specifying options for which
58 there is no separate scp command-line flag. For full details of
59 the options listed below, and their possible values, see
65 ChallengeResponseAuthentication
77 GSSAPIDelegateCredentials
80 HostbasedAuthentication
89 NoHostAuthenticationForLocalhost
90 NumberOfPasswordPrompts
91 PasswordAuthentication
94 PreferredAuthentications
99 RhostsRSAAuthentication
104 StrictHostKeyChecking
112 Specifies the port to connect to on the remote host. Note that
113 this option is written with a capital `P', because -p is already
114 reserved for preserving the times and modes of the file in
117 -p Preserves modification times, access times, and modes from the
120 -q Quiet mode: disables the progress meter as well as warning and
121 diagnostic messages from ssh(1).
123 -r Recursively copy entire directories. Note that scp follows
124 symbolic links encountered in the tree traversal.
127 Name of program to use for the encrypted connection. The program
128 must understand ssh(1) options.
130 -v Verbose mode. Causes scp and ssh(1) to print debugging messages
131 about their progress. This is helpful in debugging connection,
132 authentication, and configuration problems.
134 The scp utility exits 0 on success, and >0 if an error occurs.
137 rcp(1), sftp(1), ssh(1), ssh-add(1), ssh-agent(1), ssh-keygen(1),
138 ssh_config(5), sshd(8)
141 scp is based on the rcp(1) program in BSD source code from the Regents of
142 the University of California.
