How can i set the password for the user aaaa

---------- Post updated at 10:33 PM ---------- Previous update was at 10:06 PM ----------

I was able to set the password with command passwd.
Now i am trying to add the existing user to the existing group.
user bbbb exists and member of bbb1, now i would like to add the existing user bbbb to the existing group members using cmd: useradd -g members bbbb.
getting useradd:user bbbb exists.

useradd adds users. if the user already exists, naturally it won't be able to create it again.

usermod -a -G newgroup user The -a tells it to add the group instead of overwriting the previous group info.
