Question

输入文本文件：

COMMENT 'Sample Table'
ROW FORMAT DELIMITED
STORED AS INPUTFORMAT
  'org.apache.hadoop.mapred.TextInputFormat'
OUTPUTFORMAT
  'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
LOCATION
  'xxxxxxx'
ROW FORMAT DELIMITED
STORED AS INPUTFORMAT
  'org.apache.hadoop.hive.ql.io.orc.OrcInputFormat'
OUTPUTFORMAT
  'org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat'
LOCATION
  'xxxx'

所需的输出：

COMMENT 'Sample Table'
ROW FORMAT DELIMITED
STORED AS INPUTFORMAT
  'org.apache.hadoop.mapred.TextInputFormat'
OUTPUTFORMAT
  'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
LOCATION
  'xxxxxxx'
ROW FORMAT DELIMITED
STORED AS ORC
LOCATION
  'xxxx'

第二次出现“ STORED AS”之后，下一个单词应为ORC，并应删除下三行。在Unix中可以使用什么命令？

Answer 1

我找到了一个解决方案。如果输入保存在文件sample.txt中以下命令给出了预期的输出。

awk'/ STORED AS INPUTFORMAT / {c ++; if（c == 2）{sub（“ STORED AS INPUTFORMAT”，“ STORED AS ORC \ nzzzz”）; c = 0}} 1'sample.txt | sed -e'/ zzzz /，+ 3d'

在Unix Shell脚本中第二次出现字符串后如何替换某些行
