使用SED在文件中插入換行

我有一個文本文件中所有灰熊步主機的轉儲。下面是該文件的樣子：使用SED在文件中插入換行

(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

正如你可以看到，它的一個大巨頭運行上。我想使用sed來匹配(T並在匹配的字符串之前插入一個換行符。基本上我想輸出看起來像這樣：

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

就像這樣：

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

這工作，謝謝！ –

也許這是一個GNU擴展 - 我的sed插入一個文字'n'而我不是唯一的 - 請參閱http://www.linuxquestions.org/questions/linux-software-2/sed-insert上的最後一個答案。 -a-換行符 - 爲什麼 - 不 - 不 - 它工作-158806 / –
