I assume that you have a list of users called users_list. You may get a copy of /etc/passwd and manipulate it with sed or awk to compile the list.

Quote:
#!/bin/sh
for i in `cat users_list`
do
usermod -g new_initial_group $i
done

Chris
probly a stupid question, but where do i find the "user_list" ?

The problem is that i have 400 user who should have different primarygroup.

I got alle the usernames + password etc in an excel file.

A little more information:

The users downunder her, I want their primarygroup to be "tbu"

username

ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l513
ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l514
ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l516
ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l518



But i want these users to have primary group "tau"
LXXX = username

ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l320
ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l321
ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l324
ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l326
ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l327
ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l328
ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l329
ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l330
ou=Teachers,ou=Users,dc=skole,dc=lk,dc=local uid l333

thank you!

root@ma01:~# /etc/script/set_primary_group.sh
-bash: /etc/script/set_primary_group.sh: Permission denied


Got tips for that to ? :P

Why are you putting scripts in /etc?? Very bad place for them.

mv /etc/script/set_primary_group.sh /root/
chmod +x /root/set_primary_group.sh
/root/set_primary_group.sh

stian 08-04-2009 02:05 PM
