NAMEscp - secure copy (remote file copy program)
scp[-aAqQprvBCL1][-S path-to-ssh][-o ssh-options][-P port][-c cipher][-i identity]
Scpcopies files between hosts on a network. It usessshfor data transfer, and uses the same authentication and provides thesame security asssh.Unlikercp,scpwill ask for passwords or passphrases if they are needed forauthentication.
Any file name may contain a host and user specification to indicatethat the file is to be copied to/from that host. Copies between tworemote hosts are permitted.
- Turn on statistics display for each file.
- Turn off statistics display for each file.
- -c cipher
- Selects the cipher to use for encrypting the data transfer. Thisoption is directly passed tossh.
- -i identity_file
- Selects the file from which the identity (private key) for RSAauthentication is read. This option is directly passed tossh.
- Use non privileged port. With this you cannot userhosts or rsarhosts authentications, but it can beused to bypass some firewalls that dont allow privilegedsource ports to pass. Same as saying "-o UsePriviledgePort=no"or -P to ssh; -L is used due to exhaustion of suitable letters.
- Force scp to use command "scp1" on the remote side instead of "scp".This may be necessary in some situations, if the remote system has"scp2" symlinked to "scp".
- -o ssh-options
- Ssh options passed to ssh.
- Preserves modification times, access times, and modes from theoriginal file.
- Turn off statistics display.
- Turn on statistics display.
- Recursively copy entire directories.
- Verbose mode. Causesscpand sshto print debugging messages about their progress. This is helpful indebugging connection, authentication, and configuration problems.
- Selects batch mode (prevents asking for passwords or passphrases).
- Compression enable. Passes the -C flag tosshto enable compression.
- -P port
- Specifies the port to connect to on the remote host. Note that thisoption is written with a capital P, because -p is already reserved forpreserving the times and modes of the file in rcp.
- -S path-to-ssh
- Specifies the path to ssh program.
You can turn scp statistics on or off by settingSSH_SCP_STATSorSSH_NO_SCP_STATSenvironment variables. To turn on or off scp statistics for each file,use SSH_ALL_SCP_STATSorSSH_NO_ALL_SCP_STATSenvironment variables. The default value of the statistics can be setwhen the ssh is configured. Next the scp checks those environmentvariables and after that command line options.
