3 | NAME | ||
4 | scp - secure copy (remote file copy program) | ||
5 | |||
6 | SYNOPSIS | ||
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 | ||
10 | |||
11 | DESCRIPTION | ||
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. | ||
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 `:' 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). | ||

117 | |||
118 | -P port | ||
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 | ||
122 | rcp(1). | ||
123 | |||
124 | -p Preserves modification times, access times, and modes from the | ||
125 | original file. | ||
126 | |||
127 | -q Quiet mode: disables the progress meter as well as warning and | ||
128 | diagnostic messages from ssh(1). | ||
129 | |||
130 | -r Recursively copy entire directories. Note that scp follows | ||
131 | symbolic links encountered in the tree traversal. | ||
132 | |||
133 | -S program | ||
134 | Name of program to use for the encrypted connection. The program | ||
135 | must understand ssh(1) options. | ||
136 | |||
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. | ||
140 | |||
141 | EXIT STATUS | ||
142 | The scp utility exits 0 on success, and >0 if an error occurs. | ||

148 | HISTORY | ||
149 | scp is based on the rcp(1) program in BSD source code from the Regents of | ||
150 | the University of California. | ||
