Unix script, Operating System

Assignment Help:

As a group, you may need to make some enhancements to your development server (NOT your stable server!)  It needs to be able to run the makepasswd program, which may require installing a package with aptitude.  Other modifications may be necessary as well, depending on your solution to this part of the assignment.  If you do any of the work in making sure that this stuff is working for your group, be sure to log it with plod (the logging happens on your stable server, even though the work is being done on your development server).

Automating account creation -- Write a script called "create_user" which will will create a user account that will work with a group of other accounts. The user ID, unencrypted password, and a group name must be provided on the command line.  Your script should:

1.Create the user account, with the primary group being named the same as the user (as usual). It should have a standard home directory.
2.Change the user's .profile so that it sets their umask to make all created files and directories readable by everyone and writable by group (as well as by owner).
3.Create a group from the group name, and add the user to it as a secondary group for that user
4.Create a directory in /home for the group, named with the group name.  Make it owned by the root user and the group.  Make it so that any file created in this directory will be owned by the group as well.
5.It should do all these things without any interactive input.  All input should be provided by the values on the command line when the script is run.
