NAME    [Toc]    [Back]

     scp - secure copy (remote file copy program)

SYNOPSIS    [Toc]    [Back]

     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    [Toc]    [Back]

     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_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      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    [Toc]    [Back]
