About rcp

Copies files from one computer to another computer.

Note: RCP is not a secure or encrypted method of transferring files! For transferring files securely, use scp or rsync, which encrypt the connection to the remote host.

rcp syntax

rcp [-p] [-r] filename ... directory


-p Attempt to give each copy the same modification times, access times, modes, and ACLs if applicable as the original file.
-r Copy each subtree rooted at filename; in this case the destination must be a directory.
filename Name of the file
directory Name of the directory


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

rcp tmp/file myhost:/tmp/file

will result in a severely corrupted file.

rcp may not correctly fail when the target of a copy is a file instead of a directory.

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.

rcp does not properly handle symbolic links. Use tar or cpio piped to rsh to obtain remote copies of directories containing symbolic links or named pipes.

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

rcp will fail if you copy ACLs to a file system that does not support ACLs.

rcp examples

rcp /mydirectory/myfile hope:otherdir/myfile

This command copies the file myfile from the local path /mydirectory to the remote system named hope, placing it in the directory otherdir.
