Help me!First time use UNIX.

I am assigned a programming work.It is my first time to use unix.

The task is writing a shell script to interrogate the university Unix operating system to determine the number of "Runnable" processes at any given time.Then append the result,along with a time-stamp,on a log file. Also there are other threads programming assignments using c.

Although it is simple for everybody,but it is due next week. My background is not computer science.I just take "Operating System", and I never use unix before.So it is a taugh homework for me.

My question is:
1. The teacher requires me to submit a hard copy of the source code for each of the programs.
What does it mean? Is it mean to copy unix files to a CD or flash drive?
2.Could anyone give me an example of such a shell script or detail steps?

Thanks in advance!

NAME
times - shell built-in function to report time usages of the current shell SYNOPSIS
sh times ksh times DESCRIPTION
sh Print the accumulated user and system times for processes run from the shell. ksh Print the accumulated user and system times for the shell and for processes run from the shell. 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. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
