Useradd Options

I have come across some of the useradd options. Check out !!!

To create the user ‘nobs’ with home directory

# useradd -d /home/nobs nobs

To create a user with root privilage

# useradd -u 0 -o nobs

-u : UID 0 -> root
-o : Duplicate UID

# id nobs
uid=0(root) gid=502(nobs) groups=0(root)

The default home directory would be /home ; You can change it by editing the HOME directive on the file : “/etc/default/useradd”

HOME=/nobs
