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

rename
RENAME(1) User Commands RENAME(1)
NAME
rename - rename files
SYNOPSIS
rename [options] expression replacement file...
DESCRIPTION
rename will rename the specified files by replacing the first occurrence of expression in their name by replacement.
OPTIONS
-v, --verbose
Give visual feedback which files where renamed, if any.
-V, --version
Display version information and exit.
-s, --symlink
Peform rename on symlink target
-h, --help
Display help text and exit.
EXAMPLES
Given the files foo1, ..., foo9, foo10, ..., foo278, the commands
rename foo foo0 foo?
rename foo foo0 foo??
will turn them into foo001, ..., foo009, foo010, ..., foo278. And
rename .htm .html *.htm
will fix the extension of your html files.
WARNING
The renaming has no safeguards. If the user has permission to rewrite file names, the command will perform the action without any ques-
tions. For example, the result can be quite drastic when the command is run as root in the /lib directory. Always make a backup before
running the command, unless you truly know what you are doing.
SEE ALSO
mmv(1), mv(1)
AVAILABILITY
The rename command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
