我是新手，如何将用户添加的某个组

action08

以前gnome全是图形操作的，现在xfce取消了用户管理

想把当前用户shell添加到系统分组里面，比如www-data, kvm等等

action08

估计只有这个才行

成功

kvm终于不用输入密码了，这下也是方便多了

1. shell@localhost:~$ ps aux |grep virt
   
2. root       464  0.0  0.8 1056876 32208 ?       Ssl  09:00   0:01 /usr/sbin/libvirtd
   
3. shell     3725  1.6  1.8 1010244 68108 ?       Ssl  10:01   0:01 /usr/bin/python2 -tt /usr/share/virt-manager/virt-manager
   
4. shell     3764  0.0  0.0  12748  2236 pts/0    S+   10:03   0:00 grep virt
   
5. shell@localhost:~$
