Hi Don,
What we are trying to create is a master script to run other scripts in the back ground on different machines.
to answer your questions
are the host names of the 3 machines ws1 ws2 ws3. and
is the script name located on the NIS server which is the 4th machine making the initial call script. So all machines can see and access the script and its not written on each machine saving up needed space.
hope that answered the questions: now I have got some interesting results with the code for rsh
host names are config with Csh which is stty not supported for transit. (not sure what I just said but hope it helps)
and i have a ambiguous output redirect.
IE @Don you mentioned the direct to the null. Short answer is we don't care what the output is from the call, the script outputs to a different files those files are what we are after. But I think your right about having it directed to that null.
The rsh call stops and on the ws4 and creates a PID and waits until never (endless loop in script tracking memory) have to suspend and kill pid to stop it. again its not the problem but it stopping in the master script is.
any ideas I can research in to please throw them at me too. Thanks OJT scripting got to love it.
I need to login into multiple servers thru a script run couple commands and run find command as root. I only have ssh access to the servers as a user than I can "su" to root. If you have a similar script please post it. Also if you can suggest commands that I should consider please let me know.

rsh
rsh(1M) System Administration Commands rsh(1M)NAME
rsh, restricted_shell - restricted shell command interpreter
SYNOPSIS
/usr/lib/rsh [-acefhiknprstuvx] [argument...]
DESCRIPTION
rsh is a limiting version of the standard command interpreter sh, used to restrict logins to execution environments whose capabilities are
more controlled than those of sh (see sh(1) for complete description and usage).
When the shell is invoked, it scans the environment for the value of the environmental variable, SHELL. If it is found and rsh is the file
name part of its value, the shell becomes a restricted shell.
The actions of rsh are identical to those of sh, except that the following are disallowed:
o changing directory (see cd(1)),
o setting the value of $PATH,
o pecifying path or command names containing /,
o redirecting output (> and >>).
The restrictions above are enforced after .profile is interpreted.
A restricted shell can be invoked in one of the following ways:
1. rsh is the file name part of the last entry in the /etc/passwd file (see passwd(4));
2. the environment variable SHELL exists and rsh is the file name part of its value; the environment variable SHELL needs to be set in the
.login file;
3. the shell is invoked and rsh is the file name part of argument 0;
4. the shell is invoke with the -r option.
When a command to be executed is found to be a shell procedure, rsh invokes sh to execute it. Thus, it is possible to provide to the end-
user shell procedures that have access to the full power of the standard shell, while imposing a limited menu of commands; this scheme
assumes that the end-user does not have write and execute permissions in the same directory.
The net effect of these rules is that the writer of the .profile (see profile(4)) has complete control over user actions by performing
guaranteed setup actions and leaving the user in an appropriate directory (probably not the login directory).
The system administrator often sets up a directory of commands (that is, /usr/rbin) that can be safely invoked by a restricted shell. Some
systems also provide a restricted editor, red.
EXIT STATUS
Errors detected by the shell, such as syntax errors, cause the shell to return a non-zero exit status. If the shell is being used non-
interactively execution of the shell file is abandoned. Otherwise, the shell returns the exit status of the last command executed.
