usermod hoppá

Ez kicsit meglepett: 


[root@example ~]# id test1
uid=505(test1) gid=507(test1) groups=507(test1)
[root@example ~]# usermod -G p1,p2 test1
[root@example ~]# id test1
uid=505(test1) gid=507(test1) groups=507(test1),506(p2),510(p1)
[root@example ~]# usermod -G p1,p2, test1
[root@example ~]# id test1
uid=505(test1) gid=507(test1) groups=507(test1),0(root),506(p2),510(p1)
[root@example ~]# usermod -G p1,,p2 test1
[root@example ~]# id test1
uid=505(test1) gid=507(test1) groups=507(test1),0(root),506(p2),510(p1)

Szóval kerül a -G stringbe egy plusz vessző, és máris tagja a root csoportnak. Hát azért...

Amúgy Centos 5.1.

BUG! 


(hardy)root@test:/# useradd -u 1002 -d /home/test -g users test
(hardy)root@test:/# id test
uid=1002(test) gid=100(users) groups=100(users)
(hardy)root@test:/# usermod -G audio,games test
(hardy)root@test:/# id test
uid=1002(test) gid=100(users) groups=100(users),29(audio),60(games)
(hardy)root@test:/# usermod -G audio,games, test
usermod: unknown group
(hardy)root@test:/# usermod -G audio,,games test
