need help about system status report script!!!
hi
i m new to this forum as well as UNIX. I've got an assignment but i don't know how can I start it.
can anyone please help to tell me how can I start it?
I added here few lines from my assignment.
In industry, it is common for a single organisation to provide technical support for a substantial number of UNIX systems distributed across a large geographical area and a number of different companies. This type of support has many complications, one problem is that the company offering support may not have current information on how the UNIX based computers are being used and how they are configured.
A common approach to this problem is for each UNIX machine to contain a shell script that when executed produces a report (a text file) on the current configuration and usage of the machine. This report can then be sent to the organisation responsible for technical support.
In this assignment you are required to write such a script, suitable for use on a Linux (Fedora 5) machine.
When the “system status report” script is invoked the user should be presented with a menu. This will provide a list of options allowing the user to decide what the report should contain. The resultant text file report can be e-mailed or faxed to the technical support team.
I can't understand how can I email or fax this report to technical suppot team and also how can I produce a text report?
please I need all of ur help and I m requesting all of u to help me.
Thank you all

exit(1) User Commands exit(1)
NAME
exit, return, goto - shell built-in functions to enable the execution of the shell to advance beyond its sequence of steps
SYNOPSIS
sh
exit [n]
return [n]
csh
exit [ ( expr )]
goto label
ksh
*exit [n]
*return [n]
DESCRIPTION
sh
exit will cause the calling shell or shell script to exit with the exit status specified by n. If n is omitted the exit status is that of
the last command executed (an EOF will also cause the shell to exit.)
return causes a function to exit with the return value specified by n. If n is omitted, the return status is that of the last command exe-
cuted.
csh
exit will cause the calling shell or shell script to exit, either with the value of the status variable or with the value specified by the
expression expr.
The goto built-in uses a specified label as a search string amongst commands. The shell rewinds its input as much as possible and searches
for a line of the form label: possibly preceded by space or tab characters. Execution continues after the indicated line. It is an error to
jump to a label that occurs between a while or for built-in command and its corresponding end.
ksh
exit will cause the calling shell or shell script to exit with the exit status specified by n. The value will be the least significant 8
bits of the specified status. If n is omitted then the exit status is that of the last command executed. When exit occurs when executing
a trap, the last command refers to the command that executed before the trap was invoked. An end-of-file will also cause the shell to exit
except for a shell which has the ignoreeof option (See set below) turned on.
return causes a shell function or '.' script to return to the invoking script with the return status specified by n. The value will be the
least significant 8 bits of the specified status. If n is omitted then the return status is that of the last command executed. If return
is invoked while not in a function or a '.' script, then it is the same as an exit.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
