scp — OpenSSH
secure file copy
scp copies files between hosts on a
It uses ssh(1) for data transfer, and uses the same authentication and provides the same security as a login session.
scp will ask for passwords or passphrases
if they are needed for authentication.
The source and target
may be specified as a local pathname, a remote host with optional path in
the form [user@]host:[path], or a URI in the form
scp://[user@]host[:port][/path]. Local file names
can be made explicit using absolute or relative pathnames to avoid
scp treating file names containing ‘:’
as host specifiers.
When copying between two remote hosts, if the URI format is used,
a port cannot be specified on the
target if the
-R option is
The options are as follows:
-Oflag), this option selects batch mode for the second host as
scpcannot ask for passwords or passphrases for both hosts. This mode is the default.
scpto use IPv4 addresses only.
scpto use IPv6 addresses only.
-Cflag to ssh(1) to enable compression.
-M, connect directly to a local SFTP server program rather than a remote one via ssh(1). This option may be useful in debugging the client and server.
ssh. This option is directly passed to ssh(1).
scpconnection to the jump host described by destination and then establishing a TCP forwarding to the ultimate destination from there. Multiple jump hops may be specified separated by comma characters. This is a shortcut to specify a
ProxyJumpconfiguration directive. This option is directly passed to ssh(1).
sshin the format used in ssh_config(5). This is useful for specifying options for which there is no separate
scpcommand-line flag. For full details of the options listed below, and their possible values, see ssh_config(5).
-pis already reserved for preserving the times and mode bits of the file.
scpthere. This requires that
scprunning on the origin host can authenticate to the destination host without requiring a password.
scpfollows symbolic links encountered in the tree traversal.
scpchecks that the received filenames match those requested on the command-line to prevent the remote end from sending unexpected or unwanted files. Because of differences in how various operating systems and shells interpret filename wildcards, these checks may cause wanted files to be rejected. This option disables these checks at the expense of fully trusting that the server will not send unexpected filenames.
scpand ssh(1) to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configuration problems.
scp utility exits 0 on success,
and >0 if an error occurs.
scp is based on the rcp program in
BSD source code from the Regents of the University
Since OpenSSH 8.8,
scp has use the SFTP
protocol for transfers by default.
The legacy SCP protocol (selected by the
-O flag) requires execution of the remote user's
shell to perform glob(3) pattern matching.
This requires careful quoting of any characters that have special meaning to
the remote shell, such as quote characters.
