Hi,
I have a requirement to RCP the files from remote server to local server.
Also the RCP has to run in parallel. However using 'xargs' retrives 2 file names during each loop. How do we restrict to only one file name using xargs and loop till remaining files.
I use the below code for that..
Here's the runtime log. As you can see there are two files passed -(a&b
c&d) during each loop processing. How can we restrict this to one file at a time.

Hi there,
I am trying to move around 3000 files from one directory to another. The mv command is complaining from too many arguments. I tried to use the xargs command but with no luck. Could some body provide help?

I discovered that GNU's xargs has a -P option to allow its processes to run in parallel. Great! Is this a GNU thing, or is it supported by other platforms as well? (4 Replies)

rcp
RCP(1) General Commands Manual RCP(1)NAME
rcp - remote file copy
SYNOPSIS
rcp [-p] [-x] [-k realm ] [-D port] [-N] [-PN | -PO] file1 file2
rcp [-p] [-x] [-k realm] [-r] [-D port] [-N] [-PN | -PO] file ... directory
DESCRIPTION
Rcp copies files between machines. Each file or directory argument is either a remote file name of the form ``rhost:path'', or a local
file name (containing no `:' characters, or a `/' before any `:'s).
By default, the mode and owner of file2 are preserved if it already existed; otherwise the mode of the source file modified by the umask(2)
on the destination host is used.
If path is not a full path name, it is interpreted relative to your login directory on rhost. 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 uses Kerberos authentication when connecting to rhost. Each user may have a private authorization
list in a file .k5login in his login directory. Each line in this file should contain a Kerberos principal name of the form princi-
pal/instance@realm. If there is a ~/.k5login file, then access is granted to the account if and only if the originater user is authenti-
cated to one of the principals named in the ~/.k5login file. Otherwise, the originating user will be granted access to the account if and
only if the authenticated principal name of the user can be mapped to the local account name using the aname -> lname mapping rules (see
krb5_anadd(8) for more details).
OPTIONS -p attempt to preserve (duplicate) the modification times and modes of the source files in the copies, ignoring the umask.
-x encrypt all information transferring between hosts.
-k realm
obtain tickets for the remote host in realm instead of the remote host's realm as determined by krb_realmofhost(3).
-r if any of the source files are directories, copy each subtree rooted at that name; in this case the destination must be a directory.
-PN
-PO Explicitly request new or old version of the Kerberos ``rcmd'' protocol. The new protocol avoids many security problems found in
the old one, but is not interoperable with older servers. (An "input/output error" and a closed connection is the most likely
result of attempting this combination.) If neither option is specified, some simple heuristics are used to guess which to try.
-D port
connect to port port on the remote machine.
-N use a network connection, even when copying files on the local machine (used for testing purposes).
Rcp handles third party copies, where neither source nor target files are on the current machine. Hostnames may also take the form
``rname@rhost'' to use rname rather than the current user name on the remote host.
FILES
~/.k5login (on remote host) - file containing Kerberos principals that are allowed access.
SEE ALSO cp(1), ftp(1), rsh(1), rlogin(1), kerberos(3), krb_getrealm(3), rcp(1) [UCB version]
BUGS
Rcp doesn't detect all cases where the target of a copy might be a file in cases where only a directory should be legal.
Rcp is confused by any output generated by commands in a .login, .profile, or .cshrc file on the remote host.
Kerberos is only used for the first connection of a third-party copy; the second connection uses the standard Berkeley rcp protocol.
