Execute a file from a different account
Okay, I have this homework assignment, and I think I have it all down path, but I just need help with this one line.
Write a C Shell script that can be run under any CECS unix account and the script produces the following three lines output on the screen.
Requirements
1. The first line in the script file must contain the command I should type so that I can run it from my account and get the desired output. Remember, the C++ program is in your account and not in mine. You can test it by running it from another account, also, we are not in the same group.
Okay, I'm confused by the "Requirements 1" thing. I have to give him a hard copy of my C Shell script, so my only problem is that he has to have access to the C++ program saved in my account.
I'm confused what type of command would be needed for him to reach my account.
He's in a completely different category, so I'm assuming I have to set the other users category so that he can execute it, but what is needed exactly. Say I called the file "test" from directory "Program". For me to execute it, I would do this
% ./Program/test
What would be required for him to do that exact same thing? I can't find it anywhere. This is probably a stupid question, but I'm lost.

SG(1) User Commands SG(1)
NAME
sg - execute command as different group ID
SYNOPSIS
sg [-] [group [-c ] command]
DESCRIPTION
The sg command works similar to newgrp but accepts a command. The command will be executed with the /bin/sh shell. With most shells you may
run sg from, you need to enclose multi-word commands in quotes. Another difference between newgrp and sg is that some shells treat newgrp
specially, replacing themselves with a new instance of a shell that newgrp creates. This doesn't happen with sg, so upon exit from a sg
command you are returned to your previous group ID.
CONFIGURATION
The following configuration variables in /etc/login.defs change the behavior of this tool:
SYSLOG_SG_ENAB (boolean)
Enable "syslog" logging of sg activity.
FILES
/etc/passwd
User account information.
/etc/shadow
Secure user account information.
/etc/group
Group account information.
/etc/gshadow
Secure group account information.
SEE ALSO
id(1), login(1), newgrp(1), su(1), gpasswd(1), group(5), gshadow(5).
