User Management of Linux / Custom numbered UID and GID
In Linux we have a file located in /etc/passwd which contains UID,GID and encrypted password of the user and many other information. A user in Linux is identified by its UID which is located in same file. By default we have some predefined UID’s. For Ex:
UID of root User will always be 0
UID of any system user will be more than 1000 or 1000
Syntax found in /etc/passwd :
HOW TO SEE IT ?? : id -u <user_name>
We can change this number according to our requirement, this needs to be written in /etc/login.defs the values in it can be changed and we custom numbers UID’s for users in the block (MIN/MAX VALUES FOR AUTOMATIC UID SELCETION FOR USERS)
