SCP(1) BSD General Commands Manual SCP(1)NAMEscp — secure copy (remote file copy program)
SYNOPSISscp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
[-l limit] [-o ssh_option] [-P port] [-S program]
[[user@]host1:]file1 ... [[user@]host2:]file2
DESCRIPTIONscp 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
explicit 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
-C Compression enable. Passes the -C flag to ssh(1) to enable com‐
Selects the cipher to use for encrypting the data transfer. This
option is directly passed to ssh(1).
Specifies an alternative per-user configuration file for ssh.
This option is directly passed to ssh(1).
Selects the file from which the identity (private key) for public
key authentication is read. This option is directly passed to
Limits the used bandwidth, specified in Kbit/s.
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
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
-p Preserves modification times, access times, and modes from the
-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.
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.
