Batch file for adding users in bulk:
FOR /L %%i in (1,1,30) DO NET USER abc%%i 123456 /ADD

The above can only add a fixed quantity, prefix, and password.
Can it be changed so the above content can be entered manually?
That is, after running the batch file, manually enter the number of users to add ==

Like this?

set/p sl=Please enter the number of users to add:
FOR /L %%i in (1,1,%sl%) DO NET USER abc%%i 123456 /ADD

Yes, can all 3 parameters be made like this?
Number of users, username prefix, user password

At the moment I use it like this:

FOR /L %%i in (1,1,30) DO NET USER abc%i 123456 /ADD
FOR /L %%i in (1,1,30) DO net localgroup administrators abc%i /add

First add 30 users, then add all 30 users to the administrators group
Thanks to the moderator for the help

All of that is possible!

FOR /L %%i in (1,1,%sl%) DO net localgroup administrators abc%%i /add

Can the username prefix and password be added too?
