Shell Programming and Scripting

Im posting here as i posted this in the wrong section before, sorry about that.

Ok, im doing a self teaching course, im trying to understand how unix works, get and understand the basics before i hit the advance level.

Now i have this in windows, Btw im always new at windows so correct me if i have any mistakes known.

Code:

@echo off
echo.
echo SELECT OPTION
echo -------------
echo.
:menu
echo 1- Create username
echo 2- Create password
echo 3- Delete username
echo 4- Exit
echo.
pause
set /p option=enter option 1 2 3 or 4:
if %option%==1 goto createuser
if %option%==2 goto createpass
if %option%==3 goto deluser
if %option%==4 goto exit

:createuser
echo Enter username
set /p var=Username:
net user %var% /add
echo Username successfully entered
goto :end

:createpass
echo Enter password
net user %var% *
echo Password successfully entered
goto :end

:deluser
echo Enter user to be deleted
set first=%inputvar%
echo User deleted
goto :end
:exit

Whats the code for unix, is it similiar? Or completely different any help would be appreciated

If someone can do a code for create username on unix using bash it would be awesome, once i have an idea i can then try password n delete by myself before i ask for any more help.

Thank You

I suggest you begin with a tutorial.

BASH Programming - Introduction HOW-TO

Just an example of how it can be done (first get rid of the GOTO):

Thank You to both of you, i will give it a shot with the tutorial and thanks frans it does seem clearer, thats exactly what i needed, just an example, that helped me alot.

Thank You

Ok i think i understand the codes now, but how do i delete multipler users as an admin.

So just say i have 4 user accounts, how can i delete multiple users?

You could change part of your case statement:

Ahem....

As of now all the posters seem to have silently assumed that you have a Linux system for your script.

There is no generalized "adduser" or "deluser" command in Unix. Unix is not an Operating System like "WinXP" or "MVS", but more a like an architecture blueprint. This blueprint is laid down in several standardizing documents (you might hear of "POSIX" - this is such a document). These documents generally state requirements: "a Unix system has to react so-and-so under these circumstances", "the system call syscall-x() has to return this and that under these circumstances and this-and-this under any other", etc..

Somebody could write an operating system obeying all these requirements and it would be a "Unix system". (Maybe you would be not allowed to call it that way because of trade mark issues, but lets disregard this aspect for the purpose of this discussion.)

Linux Torwalds, for instance, did this and created "Linux". Linux is in fact not a real Unix, there are intricate differences, but they aren't important for your purposes. IBM did the same and they created "AIX", which is a real Unix, Hewlett Packard also created their own Unix called "HP-ux", Sun Microsystems (now Oracle) created "SunOS/Solaris", etc.. The user administration is different (albeit similar) in all these versions of Unix.

This doesn't mean the solutions given to you are wrong or bad - not at all! It is just that they are not that universal as you might believe they are.

For this reason you will find that switching from one Unix system to any other is absolutely simple - for the user. It might be quite a difference for the administrator, because this is the part where Unixes differ most.

I hope this helps.
