thank you for the response but this going to be harder than i thought so this is the details in full:
a software company has established standards with regards to the naming and organisation of files in its linux based filestore. in particular, users are directed to store files of a particular type in the same directory, for example, users sre instructed to store all word processor files in a directory named wp. for the purpose of this exercise therea re 3 types of file available - wordprocessing, spreadsheet and picture files.
up until now house keeping practices have been a bit haphazard and it has been upto the individual user as to the manner in which they organise back up of files, if indeed this is done at all. therefore the company wishes to to develop a new utility which will aid the users in backing up and restoring files in their own personal directory area. in doing this development, it should be recognised that script files are treated like any other i.e. they should be stored in a directory called scriptfiles.
only one utility is to be developed
the utility will give the user the option to back up or restore a set of files
the utility will give the user the ability to specify which type of file is to be used in a particular back up or restore session.
the utility should be robust with respect to files and directories and the possible overwriting of files; the utility should provide help to allow the novice user to make use of the utility.
hopefully someone can understand what is required (because i dont) and hopefully when i do start college it wont be as hard as this for a beginner
cheers

invsync(8) System Manager's Manual invsync(8)
NAME
invsync - Synchronizes system inventory
SYNOPSIS
/usr/bin/invsync
DESCRIPTION
The invsync utility creates a Master Synchronization Inventory (MSI) file and a Customized File Inventory (CFI) file. These files can be
used to preserve the customized or modified state of your system in the event of a new installation. The MSI file contains a complete list
of files installed by the setld utility and the state of those files when they were installed. The CFI file contains the names of those
files installed by the setld utility that have been customized or modified since the installation. The files listed in the CFI file are
overwritten if you perform a new installation of the operating system.
You must have superuser privileges to run the invsync utility.
The invsync utility calls the usync utility to create the MSI file. After the MSI file is created, the invsync utility calls the udetect
utility to compare the state of the files shown in the MSI file with the current state of the files installed on the system. If a file
state differs, an entry is written to the CFI file.
Edit the CFI file to remove the entries for files that you do not want to back up. The CFI file and the MSI file are written in the setld
inventory file format. For more information, refer to the stl_inv(4) refernce page.
RESTRICTIONS
You must have superuser privileges to run the invsync utility.
FILES
Subset lock files Subset inventory files Customized File Inventory Master Synchronization Inventory
