shell script to add and delete users in UNIX

This is a simple shell script that can be used for addition and deletion of user accounts on UNIX boxes by system administrators,though I have primarily tested it on AIX boxes.The script doesn't have an option of an automatic sudoers file entry and deletion  right now,it's for non sudo privilege users management.I will publish sudoers file enrty enabled script in next post. However for the script to work you need to have password less SSH configured from NIM server.

To run the script simply paste the script in your home directory on a NIM server and execute the script,the password less ssh would go on each server mentioned by you and create or delete the user.

Enter servernames seperated by space not in a line eg. servername1 servername2 servername3 is correct while servername1                                                                                                                                                                                              
         servername2    this is incorrect.However the script can be easily modified to read servernames from a file instead of passing them as arguement when prompted for inputting them by user
