hello! sound pretty easy! to the regular expressions: they are regular expressions - matching strings, numbers, sequences, patterns... lets take the passwd file for example: root:x:0:0:root:/root:/bin/bash daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin bin:x:2:2:bin:/bin:/usr/sbin/nologin sys:x:3:3:sys:/dev:/usr/sbin/nologin sync:x:4:65534:sync:/bin:/bin/sync games:x:5:60:games:/usr/games:/usr/sbin/nologin we could use a (simple) perl-regular-expression like this to extract username, group, home-directory, and default shell from every line: foreach (@LINE){ my ($user,$group,$home,$shell) = ($_ =~ m/(.+?)\:.+?\:.+?\:.+?\:(.+?)\:(.+?)\:(.+?)/); #... lets do whatever we like } im not sure what you mean with "APA formating"?! kind regards, mike

Hello, I have been working on this kind of stuffs for around 1 year. My work includes user creation and database Administration. I am well to work on linux/UNIX OS. Database I have been working on are: SAPDB, Sybase, Orace, DB2, HANA. Majority of the systems include linux/unix OS. Many of the tasks are being automated using perl scripts. I can assure you that the project will be completed within 2 days. What I can understand from your requirement is that, a script has to be created that:- creates a user(OS user), drop user (OS user), create a group,drop a group, Menu input options. Adding to it, check needs to be done if there is an existing user. Can you tell me the number of users we are dealing in here? Below is my proposal that will further enhance the whole thing that is:- If the number of users who can execute the script is less, authentication feature may also be added in order to validate if a user is allowed to view all the details. This thereby increases the efficiency and productivity in real time. Please contact me on my mail id which you can find in my profile. Note:- Please find below my execution plan. > The data will be gathered as per requirement. > plan that best suits the requirement will be executed. > codes will be commented in order to make any enhancement. > The code will be delivered. In each phase of the project you will be informed about the enhancements to make it more precise to be delivered and executed. Thanks Regards Ankish Poddar
