3NAME
4 scp M-bM-^@M-^S secure copy (remote file copy program)
5
6SYNOPSIS
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

11DESCRIPTION
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). scp will ask for passwords or passphrases if they are needed
15 for authentication.
16
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 M-bM-^@M-^X:M-bM-^@M-^Y as host specifiers. Copies between two remote hosts
21 are also permitted.
22
23 The options are as follows:
24
25 -1 Forces scp to use protocol 1.
26
27 -2 Forces scp to use protocol 2.
28
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
32 progress meter.
33
34 -4 Forces scp to use IPv4 addresses only.
35
36 -6 Forces scp to use IPv6 addresses only.
37
38 -B Selects batch mode (prevents asking for passwords or
39 passphrases).
40
41 -C Compression enable. Passes the -C flag to ssh(1) to enable
42 compression.
43
44 -c cipher
45 Selects the cipher to use for encrypting the data transfer. This
46 option is directly passed to ssh(1).
47
48 -F ssh_config
49 Specifies an alternative per-user configuration file for ssh.
50 This option is directly passed to ssh(1).
51
52 -i identity_file
53 Selects the file from which the identity (private key) for public
54 key authentication is read. This option is directly passed to
55 ssh(1).
56
57 -l limit
58 Limits the used bandwidth, specified in Kbit/s.
59
60 -o ssh_option
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
65 ssh_config(5).

128
129 -P port
130 Specifies the port to connect to on the remote host. Note that
131 this option is written with a capital M-bM-^@M-^XPM-bM-^@M-^Y, because -p is already
132 reserved for preserving the times and modes of the file.
133
134 -p Preserves modification times, access times, and modes from the
135 original file.
136
137 -q Quiet mode: disables the progress meter as well as warning and
138 diagnostic messages from ssh(1).
139
140 -r Recursively copy entire directories. Note that scp follows
141 symbolic links encountered in the tree traversal.
142
143 -S program
144 Name of program to use for the encrypted connection. The program
145 must understand ssh(1) options.
146
147 -v Verbose mode. Causes scp and ssh(1) to print debugging messages
148 about their progress. This is helpful in debugging connection,
149 authentication, and configuration problems.
150
151EXIT STATUS
152 The scp utility exitsM-BM- 0 on success, andM-BM- >0 if an error occurs.

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