The useradd tool in Solaris has the capability to use some defaults.
If you want to see the current defaults, you can do this via using useradd -D:
root@testbed:~# useradd -D
group=staff,10 project=default,3 basedir=/export/home
skel=/etc/skel shell=/usr/bin/bash inactive=0
expire= auths= roles= profiles= limitpriv=
defaultpriv= lock_after_retries= roleauth=
auth_profiles= clearance= min_label= pam_policy=
project= audit_flags= access_times= access_tz=
unlock_after= tpd= annotation= zfshome=yes Let’s assume you have a group admins and you want to put all new users created by useradm into this group. You use the -D option again.
root@testbed:~# useradd -D -g admins
group=admins,100 project=default,3 basedir=/export/home
skel=/etc/skel shell=/usr/bin/bash inactive=0
expire= auths= roles= profiles= limitpriv=
defaultpriv= lock_after_retries= roleauth=
auth_profiles= clearance= min_label= pam_policy=
project= audit_flags= access_times= access_tz=
unlock_after= tpd= annotation= zfshome=yes
