The useradd command is used to create new user accounts in Linux. It has many options that can be specified to customize the user creation process. Two of these options are:
* -d, --home HOME_DIR: This option allows the user to specify the absolute path to the user's home directory. The default is to append the username to the base directory specified by the HOME variable in /etc/default/useradd, or /home by default. The directory does not have to exist but will not be created if it is missing12
* -u, --uid UID: This option allows the user to specify the numeric user ID (UID) of the user. The UID must be unique and not already in use by another user. The default is to use the next available UID from the range specified by the UID_MIN and UID_MAX variables in /etc/login.defs13 References: 1: useradd(8) - Linux man page 2: How to Create Users in Linux (useradd Command) | Linuxize 3: Linux Useradd Command Help and Examples - Computer Hope
