Question { 40651 }

how many types of user accounts are available in linux os?

if i assign a uid below 500 to a normal user..wat wil be
happened?

Answer

There are 3 types of user accounts in linux.They are:
1> System Users
2> Root User(Administrator)
3> Other Users(Normal User)

In linux, Uid from 1 to 500 has been reserved for system
users,these are the default users of linux,so if anyone try
to assign Uid 500 to normal user then it wil give the error.
