Hello Everyone - Student in Need of Help

Hi everyone.

Let me just start off by saying I'm a college student and I love playing around with UNIX.

I registered here because I have a UNIX shell scripting class and I am having some issues with my homework. I'm not looking for answers to the problems, just some help to get me on my way.

Here is an example of one of the problems I'm having an issue with.

Quote:

Write a shell script called suffix that will do the following:

1. Insert a reference to the Bourne shell as the command interpreter of this shell script.
2. Add the appropriate comments
3. Test that exactly two command line argruments are enter from the command line. If not, display the usage message and stop the script and set the status to 1. If exactly two are entered, continue processing.
4. The first argument is the name of an existing file. The second agrument is a suffix to be added to the file when you rename it.
5. Rename the first file to the second file name with the suffix append on.
6. Cut and paste you program in the space provided along with a session of the samples being executed.

For example,

$ suffix memo1 .sv

should rename the file called memo1 to a file called memo1.sv

========

$ suffix memo1

Usage: suffix filename suffixname

========

$ suffix memo1 memo2 .sv

Usage: suffix filename suffixname

My main issue is that I don't know the syntax to cut and paste and redirect the output in such a way that it renames the file and everything.

If you guys can help me with the commands I'll need to make this script, I would greatly appreciate it.

net::server::proto::unix

Net::Server::Proto::UNIX(3)				User Contributed Perl Documentation			       Net::Server::Proto::UNIX(3)

NAME

       Net::Server::Proto::UNIX - Net::Server UNIX protocol.

SYNOPSIS

       See Net::Server::Proto.

DESCRIPTION

       Protocol module for Net::Server.  This module implements the UNIX SOCK_STREAM socket type.  See Net::Server::Proto.

       Any sockets created during startup will be chown'ed to the user and group specified in the starup arguments.

PARAMETERS

       The following paramaters may be specified in addition to normal command line parameters for a Net::Server.  See Net::Server for more
       information on reading arguments.

       unix_type
	   Can be either SOCK_STREAM or SOCK_DGRAM (default is SOCK_STREAM).  This can also be passed on the port line (see Net::Server::Proto).

	   However, this method is deprecated.	If you want SOCK_STREAM - just use proto UNIX without any other arguments.  If you'd like
	   SOCK_DGRAM, use the new proto UNIXDGRAM.

METHODS

       NS_unix_path/NS_unix_type
	   In addition to the standard NS_ methods of Net::Server::Proto classes, the UNIX types also have legacy calls to NS_unix_path and
	   NS_unix_type.

	   Since version 2.000, NS_unix_path is simply an alias to NS_port.  NS_unix_type is now redundant with NS_proto.

	   These methods were missing between version 2.000 and 2.003 but have been returned as legacy bridges.

QUICK PARAMETER LIST

	 Key		   Value		    Default

	 # deprecated UNIX socket parameters
	 unix_type	   (SOCK_STREAM|SOCK_DGRAM) SOCK_STREAM
	 port		   "filename"		    undef

	 # more recent usage
	 port		   "filename / UNIX"
	 port		   "filename / UNIXDGRAM"

LICENCE

       Distributed under the same terms as Net::Server
