The reason for your problem is the command evaluation process in ksh. You might want to read what i have written for a different (but related) problem here.
Your commandline is first interpreted locally and the content of the variable is filled in and protected by the double quotes. Now a remote connection is opened and the rest of the line is passed as command line to the remote shell interpreter. Guess what? At the remote site the commandline is getting interpreted *again* and now the double quotes are not there any more because they are already "used". The command will look like this (first line=local, second line=remote):
And of course "grep" will try to find "^Sat" is a file called "Jun", which leads to the error.
The solution is to protect your double quotes by escaping them:

rsh
rsh(1c)rsh(1c)Name
rsh - remote shell
Syntax
rsh host [-l username] [-n] command
host [-l username] [-n] command
Description
The command connects to the specified host, and executes the specified command. The command copies its standard input to the remote com-
mand, the standard output of the remote command to its standard output, and the standard error of the remote command to its standard error.
Interrupt, quit and terminate signals are propagated to the remote command. The command normally terminates when the remote command does.
The remote username used is the same as your local username, unless you specify a different remote name with the -l option. This remote
name must be equivalent, in the sense of to the originating account. No provision is made for specifying a password with a command.
If you omit command, then instead of executing a single command, you are logged in on the remote host using
Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote
machine. Thus the command
rsh otherhost cat remotefile >> localfile
appends the remote file remotefile to the localfile localfile, while
rsh otherhost cat remotefile ">>" otherremotefile
appends remotefile to otherremotefile.
Host names are given in the file Each host has one standard name (the first name given in the file), which is rather long and unambiguous,
and optionally one or more nicknames. The host names for local machines are also commands in the directory If you put this directory in
your search path then the can be omitted.
Options-l username Logs you in as the specified user, not as your user login name.
-n Redirects all command input to
Restrictions
The command is confused by output generated by commands in a .cshrc file on the remote host. In particular, `where are you?' and `stty:
Can't assign requested address' are messages which can result if output is generated by the startup file.
If you are using and put a in the background without redirecting its input away from the terminal, it blocks even if no reads are posted by
the remote command. If no input is desired you should redirect the input of to using the -n option.
You cannot run an interactive command like Use
Stop signals stop the local process only.
