Full Discussion: copy the latest file in the remote server's directory

Have you tried using scp instead of a nested ssh command? Here's an example below (without any ${} or {$})

Code:
### This is one line - broken down to improve readability
scp -rp REMOTE_USERID@REMOTE_HOSTNAME:SOURCE_FILE`ssh 
REMOTE_USERID@REMOTE_HOSTNAME ls -tr1 /SOURCE_FILE | tail -1` 
REMOTE_USERID@REMOTE_HOSTNAME:TARGET_FILE

I tested by running the following from myhost1:
Code:
scp -rp avronius@myhost2:/opt/home/avronius/misc/`ssh 
avronius@myhost2 ls -tr1 /opt/home/avronius/misc/ | tail -1` 
avronius@myhost2:/opt/home/avronius/misc/newfile

rfcp

RFCP(1) 							Rfio User Commands							   RFCP(1)

NAME

       rfcp - Remote file copy

SYNOPSIS

       rfcp [ -s size ] [ -v2 ] filename1 filename2
       rfcp [ -s size ] [ -v2 ] filename directory

       On Windows only:
       rfcp [ -a ] [ -b ] [ -s size ] [ -v2 ] @command_file

DESCRIPTION

       The  remote  file  I/O copy program provides an interface to the shift remote file I/O daemon (rfiod) for transferring files between remote
       and/or local hosts. Each filename or directory argument is either a remote file name of the form:

	      hostname:path

       or a local file name (not containing the :/ character combination). The standard input is supported with the - character. Then directory in
       output is not supported.

OPTIONS

       -a     tells rfcp that the source file is ASCII text (Windows/NT only)

       -b     tells rfcp that the source is a binary file (Windows/NT only)

       -s size
	      If specified, only size bytes will be copied

       -v2    If specified, forces the RFIO V.2 protocol. Otherwise, V.3 (streaming mode) is used.

RETURN CODES

       0    Ok.
       1    Bad parameter.
       2    System error.
       3    Unknown error.
       16   Device or resource busy.
       28   No space left on device.
       196  Request killed.
       198  Stager not active.
       200  Bad checksum.
