numcli con show （Error: System - no such connection profile.）报错问题解决

 

这个问题我的原因是

网卡名称带有空格。命令无法显示。加上双引号就可以啦。

[root@liruilong ~]# nmcli connection show
NAME         UUID                                  TYPE      DEVICE 
System eth0  5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03  ethernet  eth0   

[root@liruilong ~]# nmcli con show System eth0
Error: System - no such connection profile.

解决办法：

[root@liruilong ~]# nmcli con show "System eth0"
connection.id:                          System eth0
connection.uuid:                        5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03
