1)It should be named “buser”

2)It should live in the /root/bin directory.

3)It should be executable by the root user.

4)It should accept the command line parameters in the following syntax:


SYNOPSIS
buser [-a] [-d] [-l] [--add] [--delete] [--list] [filename...]

DESCRIPTION
This documents the IT 240 version of buser. This program adds, creates or lists multiple user accounts from a provide list in the form of a file specified at the command line.

OPTIONS
-a, --add

Make a user account for each username contained in the named file.

-d, --delete

Delete user accounts listed in the named file.

-l, --list

Display the user account line from /etc/passwd for each user account name in the named file.



1)When run, the script should look at the command line parameters and act appropriately.

2)It should use the file named at the command line as the source of accounts to act upon. The named file in the command line will be a list of user account names of unknown number. Each account name will be separated by a carriage return.

3) When creating/adding accounts, the script should also create home directories.

4) When deleting accounts, the script should also delete user home directories.

5)When listing accounts, the script should cause the line in /etc/password that corresponds to each account in the named file to be displayed.
