我有一个包含以下几行的文件
This is an PLUTO
This is PINEAPPLE
This is ORANGE
This is RICE
如何在每行上方创建一个新行并将最后一个字符串插入到新行输出中，如下所示：
PLUTO:
This is an PLUTO
PINEAPPLE:
This is an PINEAPPLE
ORANGE:
This is an ORANGE
RICE:
This is an RICE
谢谢
我有一个文件如下：
This is an _PLUTO_
This is _PINEAPPLE_
This is _ORANGE_
This is _RICE_
我使用下面的代码来提取输出：
awk '{ print "Country: " $NF }' report.txt
输出：
Country: _PLUTO_
Country: _PINEAPPLE_
Country: _ORANGE_
Country: _RICE_
如何删除所有下划线，以便我的输出如下所示：
Country: PLUTO
Country: PINEAPPLE
Country: ORANGE
Country: RICE
