如何在匹配前插入带有文本的新行

Question

我能够从文本文件中提取这些行

TBL Papers
Papers_ShortName "TPJ341861"
Papers_Name "BANK    240314 341861    "
MMInstrumentType P "Discounted Paper"

但想插入一个新行（匹配TBL论文前的文字）。看到预期的产出

ACTION "INS"
TBL Papers
Papers_ShortName "TPJ341861"
Papers_Name "BANK    240314 341861    "
MMInstrumentType P "Discounted Paper"

我该怎么做？感谢

Answer 1

使用awk

awk '/TBL Papers/ {$0="ACTION \"INS\"" RS$0}8' file
ACTION "INS"
TBL Papers
Papers_ShortName "TPJ341861"
Papers_Name "BANK    240314 341861    "
MMInstrumentType P "Discounted Paper"

此代码将在模式TBL Papers上方添加一行，然后将所有内容打印出来。

Answer 2

awk '/TBL Papers/{ print "ACTION \"INS\"" } 1' file
