Need assistance with a file issue and a terminal issue
Hello everyone, I'm in need of some assistance. I'm currently enrolled in an introductory UNIX shell programming course and, well halfway through the semester, we are receiving our first actual assignment. I've somewhat realized now that I've fallen behind, and I'm working to get caught up, but for now I really could use some clarification on the two different tasks I need to setup in csh.

First one I've got about halfway finished. The assignment is to write a csh script that takes in a file and a directory name as parameters, validates that both arguments exist, then reads in a list of file names located in the parameter file and creates backups of those files within the param directory. I've got the permissions down, and I think I can handle creating the backup files, but I can't figure out any good way to read the file names from within the param file. Any commands I should be aware of here?

Second, and I haven't quite gotten very far on this one just yet, I need to create a simple script program which displays a welcome message to the user that opens it, but is only accessible from a specific terminal. Accessing the script from a different terminal should cause the program to immediately exit. Seems simple enough, but I don't know how to access the terminal ID or find any way to identify it.

If anyone is feeling generous enough to offer some assistance/clarification, I would greatly appreciate some help here. I'm pretty well stuck.

platform::shell

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
