I live in a network with nearly 5000 servers passthrough with nsh or ssh , this script is designed for the nsh shell but it can also be tweaked to work with ssh .
The first part uptil the file handlers for grp.tmp and etcpswd.tmp is for taking the input for the group and users to clone and copying it from the source server to a temporary file in the grp.tmp and the etcpswd.tmp.
The users are again filtered in the input as it sometimes happens that the source server contains a lot of users and the users to clone are not all of them but a few of them. $userex
The users are put in an array @userexarr and then using a for loop the array elements are put in separate variables .
The script might appear longer as the comment field in the user field is populated with the service request no. , the people soft id and the details of the user.
Afterwards when all the variables are populated it is just passed to the nsh shell with useradd and the usual expect statements for setting the password .
If required the script can be shortened without the people soft id and the service request no. but it depends on the environment to be implemented .
