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  secu-
       rity  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 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  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  pro-
              gram 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.

HISTORY

       scp is based on the rcp(1) program in BSD source code from the  Regents
       of the University of California.
