NAME

rcp − remote file copy

SYNOPSIS

rcp [ −p ] filename1 filename2
rcp [ −pr ] filename...directory

DESCRIPTION

The rcp command copies files between machines.  Each filename or directory argument is either a remote file name of the form:

hostname:path

or a local file name (containing no : characters, or a / before any : characters). 

If a filename is not a full path name, it is interpreted relative to your home directory on hostname. A path on a remote host may be quoted (using \, ", or ’) so that the metacharacters are interpreted remotely.

rcp does not prompt for passwords; your current local user name must exist on hostname and allow remote command execution by rsh(1). 

rcp handles third party copies, where neither source nor target files are on the current machine.  Hostnames may also take the form

username@hostname:filename

to use username rather than your current local user name as the user name on the remote host.  rcp also supports Internet domain addressing of the remote host, so that:

username@host.domain:filename

specifies the username to be used, the hostname, and the domain in which that host resides.  Filenames that are not full path names will be interpreted relative to the home directory of the user named username, on the remote host.

The destination hostname may also take the form hostname.username:filename to support destination machines that are running older versions of rcp. 

The following options are available:

−p Attempt to give each copy the same modification times, access times, and modes as the original file. 

−r Copy each subtree rooted at filename; in this case the destination must be a directory.

FILES

$HOME/.profile

SEE ALSO

ftp(1), rlogin(1), rsh(1), hosts.equiv(4). 

NOTES

rcp is meant to copy between different hosts; attempting to rcp a file onto itself, as with:

rcp tmp/file myhost:/tmp/file

results in a severely corrupted file. 

rcp does not detect all cases where the target of a copy might be a file in cases where only a directory should be legal. 

rcp can become confused by output generated by commands in a $HOME/.profile on the remote host. 

rcp requires that the source host have permission to execute commands on the remote host when doing third-party copies. 

If you forget to quote metacharacters intended for the remote host you get an incomprehensible error message. 

If you are copying a directory to a remote machine, rcp −r behaves differently if the directory name ends with a slash (/).  If the directory name is specified without a slash, rcp creates a new directory with that name on the remote machine and puts the contents of the local directory into the newly created remote directory.  If the directory name ends with a slash, rcp copies the contents of the local directory but does not create a new directory on the remote machine. 

For example, assume that your local machine has the directory stuff that contains file1 and file2.  You are copying this directory to /tmp/things on the remote machine.  The command

rcp −r stuff remote:/tmp/things

would create this directory structure:

remote:/tmp/things/stuff/file1
remote:/tmp/things/stuff/file2

On the other hand, the command

rcp −r stuff/ remote:/tmp/things

would create this directory structure:

remote:/tmp/things/file1
remote:/tmp/things/file2
