NAME
scp - secure copy (remote file copy program)
SYNOPSIS
scp [-aAqQprvBCL] [-S path-to-ssh] [-o ssh-options] [-P port]
[-c cipher] [-i identity]
[[user@]host1:]filename1... [[user@]host2:]filename2
DESCRIPTION
Scp copies files between hosts on a network. It uses ssh for data
transfer, and uses the same authentication and provides the same
security as shh. Unlike rcp, 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.
OPTIONS
-a Turn on statistics display for each file.
-A Turn off statistics display for each file.
-cc cipher
Selects the cipher to use for encrypting the data transfer.
This option is directly passed to ssh.
-i identity_file
Selects the file from which the identity (private key) for RSA
authentication is read. This option is directly passed to ssh.
-L Use non privileged port. With this you cannot use rhosts or
rsarhosts authentications, but it can be used to bypass some
firewalls that dont allow privileged source ports to pass. Same
as saying "-o UsePriviledgePort=no" or -P to ssh; -L is used due
to exhaustion of suitable letters.
-o ssh-options
Ssh options passed to ssh.
-p Preserves modification times, access times, and modes from the
original file.
-q Turn off statistics display.
-Q Turn on statistics display.
-r Recursively copy entire directories.
- 1 -
-
v Verbose mode. Causes scp and ssh to print debugging messages
about their progress. This is helpful in debugging connection,
authentication, and configuration problems.
-B Selects batch mode (prevents asking for passwords or
passphrases).
-C Compression enable. Passes the -C flag to ssh to enable
compression.
-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.
-S path-to-ssh
Specifies the path to ssh program.
ENVIRONMENT VARIABLES
You can turn scp statistics on or off by setting SSH_SCP_STATS or
SSH_NO_SCP_STATS environment variables. To turn on or off scp
statistics for each file, use SSH_ALL_SCP_STATS or
SSH_NO_ALL_SCP_STATS environment variables. The default value of the
statistics can be set when the ssh is configured. Next the scp checks
those environment variables and after that command line options.
