what different between two instruction
cp -r
rcp -r
"cp"=copy, "rcp"=remote copy. Does that answer your question?

you have to copy it somewhere. This "somewhere" will be included in "cp -r"s scope because "cp -r" works recursively. If you don't take extra care and simply issue
cp will first copy everything to "/somewhere", then create a copy of "/somewhere" in "/somewhere/somewhere", then create a copy of "/somewhere/somewhere" in "/somewhere/somewhere/somewhere", ... It will create an infinite recursion until at some point it will simply exhaust the disk space. This is probably not what you had in mind when you issued the command.

Either use "rcp", because the destionation will be on another machine and therefore not interfere or use "tar" and a special file mask so that the resulting tar-file is not included in "tar"s scope - or something similar. In general: avoid the recursion leading to the destination being included in the target.

Hi!
Daily, one of our RedHat Enterprise servers tries to get some files from other RedHat Enterprise server through rcp. Strangely, only the smallest files (about 80K) are transferred, the larger ones (about 40Mb) are not. The rcp doesn't issue any error message, only keeps waiting and waiting... (0 Replies)

rcp
RCP(1) BSD General Commands Manual RCP(1)NAME
rcp -- remote file copy
SYNOPSIS
rcp [-px] file1 file2
rcp [-px] [-r] file ... directory
DESCRIPTION
Rcp copies files between machines. Each file or directory argument is either a remote file name of the form ``rname@rhost:path'', or a local
file name (containing no `:' characters, or a `/' before any `:'s).
-r If any of the source files are directories, rcp copies each subtree rooted at that name; in this case the destination must be a direc-
tory.
-p The -p option causes rcp to attempt to preserve (duplicate) in its copies the modification times and modes of the source files, ignor-
ing the umask. By default, the mode and owner of file2 are preserved if it already existed; otherwise the mode of the source file mod-
ified by the umask(2) on the destination host is used.
If path is not a full path name, it is interpreted relative to the login directory of the specified user ruser on rhost, or your current user
name if no other remote user name is specified. A path on a remote host may be quoted (using , ", or ') so that the metacharacters are
interpreted remotely.
Rcp does not prompt for passwords; it performs remote execution via rsh(1), and requires the same authorization.
Rcp handles third party copies, where neither source nor target files are on the current machine.
SEE ALSO cp(1), ftp(1), rsh(1), rlogin(1)HISTORY
The rcp command appeared in 4.2BSD.
BUGS
Doesn't detect all cases where the target of a copy might be a file in cases where only a directory should be legal.
Is confused by any output generated by commands in a .login, .profile, or .cshrc file on the remote host.
The destination user and hostname may have to be specified as ``rhost.rname'' when the destination machine is running the 4.2BSD version of
rcp.
