NAME
scp - secure copy (remote file copy program)
SYNOPSIS
scp -words [-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.
Any file name may contain a host and user specification to
indicate that the file is to be copied to/from that host. Copies
between two remote hosts are 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
passphrases).
- -C
- Compression enable. Passes the -C flag to ssh(1) to enable
compression.
- -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 RSA
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_config5. 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_config5.

- -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
- Disables the progress meter.
- -r
- Recursively copy entire directories.
- -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.
DIAGNOSTICS
scp exits with 0 on success or >0 if
an error occurred.
