SCP(1) OpenBSD Reference Manual SCP(1)

|
|
|
NAME
|
|
scp - secure copy (remote file copy program)
|
|
|
|
SYNOPSIS
|
|
scp [-1246BCpqrv] [-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 ex-
|
|
plicit 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.
|
|
|
|
-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 passphras-
|
|
es).
|
|
|
|
-C Compression enable. Passes the -C flag to ssh(1) to enable com-
|
|
pression.
|
|
|
|
-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 sym-
|
|
bolic 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.
|
|
|
|
The scp utility exits 0 on success, and >0 if an error occurs.
