使用 SED 在文件中插入换行符

Question

我有一个文本文件中所有 grizzly-step 主机的转储。这是文件的样子：

(Table: network_objects) Name: Bad-Host_89.b.c.d (Table: network_objects) Name: Bad-Host_89.b.c.d (Table: network_objects) Name: Bad-Host_89.b.c.d (Table: network_objects) Name: Bad-Host_89.b.c.d (Table: network_objects) Name: Bad-Host_89.b.c.d (Table: network_objects) Name: Bad-Host_89.b.c.d (Table: network_objects) Name: Bad-Host_89.b.c.d (Table: network_objects) Name: Bad-Host_89.b.c.d (Table: network_objects) Name: Bad-Host_89.b.c.d (Table: network_objects) Name: Bad-Host_89..b.c.d (Table: network_objects) Name: Bad-Host_89.b.c.d (Table: network_objects) Name: Bad-Host_89.b.c.d (Table: network_objects) Name: Bad-Host_89.b.c.d (Table: network_objects) Name: Bad-Host_89.b.c.d

如您所见，它是一个巨大的连续运行。我想使用 sed 来匹配 (T 并在匹配的字符串之前插入换行符。基本上我希望输出看起来像这样：

(Table: network_objects) Name: Bad-Host_89..b.c.d  
(Table: network_objects) Name: Bad-Host_89..b.c.d 
...

就像这样：

AMD$ sed 's/(T/\n&/g' File

(Table: network_objects) Name: Bad-Host_89.b.c.d
(Table: network_objects) Name: Bad-Host_89.b.c.d
(Table: network_objects) Name: Bad-Host_89..b.c.d
(Table: network_objects) Name: Bad-Host_89..b.c.d
(Table: network_objects) Name: Bad-Host_89..b.c.d
(Table: network_objects) Name: Bad-Host_89..b.c.d
(Table: network_objects) Name: Bad-Host_89..b.c.d
(Table: network_objects) Name: Bad-Host_89..b.c.d
(Table: network_objects) Name: Bad-Host_89..b.c.d
(Table: network_objects) Name: Bad-Host_89..b.c.d
(Table: network_objects) Name: Bad-Host_89..b.c.d
(Table: network_objects) Name: Bad-Host_89..b.c.d
(Table: network_objects) Name: Bad-Host_89..b.c.d
(Table: network_objects) Name: Bad-Host_89.b.c.d
