| 3 | NAME | ||
| 4 | scp - secure copy (remote file copy program) | ||
| 5 | |||
| 6 | SYNOPSIS | ||
| 7 | scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file] | ||
| 8 | [-l limit] [-o ssh_option] [-P port] [-S program] | ||
| 9 | [[user@]host1:]file1 ... [[user@]host2:]file2 | ||
| 10 | |||
| 11 | DESCRIPTION | ||
| 12 | scp copies files between hosts on a network. It uses ssh(1) for data | ||
| 13 | transfer, and uses the same authentication and provides the same security | ||
| 14 | as ssh(1). Unlike rcp(1), scp will ask for passwords or passphrases if | ||
| 15 | they are needed for authentication. | ||
| 16 | |||
| 17 | File names may contain a user and host specification to indicate that the | ||
| 18 | file is to be copied to/from that host. Local file names can be made ex- | ||
| 19 | plicit using absolute or relative pathnames to avoid scp treating file | ||
| 20 | names containing `:' as host specifiers. Copies between two remote hosts | ||
| 21 | are also permitted. | ||
| 22 | |||
| 23 | The options are as follows: | ||
| 24 | |||
| 25 | -1 Forces scp to use protocol 1. | ||
| 26 | |||
| 27 | -2 Forces scp to use protocol 2. | ||
| 28 | |||
| 29 | -4 Forces scp to use IPv4 addresses only. | ||
| 30 | |||
| 31 | -6 Forces scp to use IPv6 addresses only. | ||
| 32 | |||
| 33 | -B Selects batch mode (prevents asking for passwords or passphras- | ||
| 34 | es). | ||
| 35 | |||
| 36 | -C Compression enable. Passes the -C flag to ssh(1) to enable com- | ||
| 37 | pression. | ||
| 38 | |||
| 39 | -c cipher | ||
| 40 | Selects the cipher to use for encrypting the data transfer. This | ||
| 41 | option is directly passed to ssh(1). | ||
| 42 | |||
| 43 | -F ssh_config | ||
| 44 | Specifies an alternative per-user configuration file for ssh. | ||
| 45 | This option is directly passed to ssh(1). | ||
| 46 | |||
| 47 | -i identity_file | ||
| 48 | Selects the file from which the identity (private key) for public | ||
| 49 | key authentication is read. This option is directly passed to | ||
| 50 | ssh(1). | ||
| 51 | |||
| 52 | -l limit | ||
| 53 | Limits the used bandwidth, specified in Kbit/s. | ||
| 54 | |||
| 55 | -o ssh_option | ||
| 56 | Can be used to pass options to ssh in the format used in | ||
| 57 | ssh_config(5). This is useful for specifying options for which | ||
| 58 | there is no separate scp command-line flag. For full details of | ||
| 59 | the options listed below, and their possible values, see | ||
| 60 | ssh_config(5). | ||

| 108 | UserKnownHostsFile | ||
| 109 | VerifyHostKeyDNS | ||
| 110 | |||
| 111 | -P port | ||
| 112 | Specifies the port to connect to on the remote host. Note that | ||
| 113 | this option is written with a capital `P', because -p is already | ||
| 114 | reserved for preserving the times and modes of the file in | ||
| 115 | rcp(1). | ||
| 116 | |||
| 117 | -p Preserves modification times, access times, and modes from the | ||
| 118 | original file. | ||
| 119 | |||
| 120 | -q Quiet mode: disables the progress meter as well as warning and | ||
| 121 | diagnostic messages from ssh(1). | ||
| 122 | |||
| 123 | -r Recursively copy entire directories. Note that scp follows sym- | ||
| 124 | bolic links encountered in the tree traversal. | ||
| 125 | |||
| 126 | -S program | ||
| 127 | Name of program to use for the encrypted connection. The program | ||
| 128 | must understand ssh(1) options. | ||
| 129 | |||
| 130 | -v Verbose mode. Causes scp and ssh(1) to print debugging messages | ||
| 131 | about their progress. This is helpful in debugging connection, | ||
| 132 | authentication, and configuration problems. | ||
| 133 | |||
| 134 | The scp utility exits 0 on success, and >0 if an error occurs. | ||
