轉換文件的多行文件每行單個字符串

Question

對不起，問一個簡單的問題，我有一個文本文件名爲文件1與很多行大多是句子。我想用空格作爲分隔符來分隔這些行，並將這些字符串作爲每行1個打印到名爲的另一個文件file2我該如何在UNIX中執行此操作？下面給出

的文件1看起來內容：

文件1

build targets target1 , target2, target3 in both windows machines 
please rebuild target 4 build target5 as well as target6 
target1 abc/saddggav/aafvfaddf/adfbdafdb/text1.msg 
target2 dfdfbd/afbdahgtngs/adbadfdsbsdb/snstnhdb/text2.msg 
target2 
target6 
please take all the files from dsvdfdfv/afedfgbadvbath/dsfbdsgfabadbafd/sdfbdgnsdb/dsfbwsgdb 
please rebuild "build target4 and build target6 on sun machines 

我想排除之間的所有路徑，但必須採取目標在該行的開頭並將所有單詞作爲每1行1個字符串打印到另一個文件file2。

有人可以幫我解決這個問題嗎？
