Question

所以我几天来一直在努力解决这个问题，尝试使用grep，sed和awk的解决方案，所有解决方案都在某种程度上有效但不符合我的确切要求。以下是我正在使用的数据。我需要在每个新行--------字符串之间提取二等奖，或者在列表中的每个域之间获得一等奖。

我需要为每个域提取特定的数据库详细信息。

somedomain.co.za

\---------------------------

Database name   somedb_db1

Full    somepassword

Login   somelogin_1

Read only       somepassword

Read/Write      somepassword

Server name     some.host.net

somedomain.org.za

\---------------------------

Database name   somedb_db1

Full    somepassword

Login   somelogin

Read only       somepassword

Read/Write      somepassword

Server name     some.host.net

somedomain.co.za

\---------------------------

Database name   somedb_db1

Full    somepassword

Login   somelogin_1

Read only       somepassword

Read/Write      somepassword

Server name     some.host.net

somedomain.co.za

\---------------------------

Server name     some.host.net

Database name   somedb_wp

Full    somepassword

Login   somelogin_4

Read/Write      somepassword

Read only       somepassword

Server name     some.host.net

Read/Write      somepassword

Read only       somepassword

Login   somelogin_3

Full    somepassword

Database name   somedb_db3

somedomain.co.za

\---------------------------

Answer 1

我发现这个问题相当模糊，但我认为您可能正在寻找类似awk脚本的内容：

/.*\.(co|org)\.za/ { print RECORD; RECORD = $0; next }
{ RECORD = RECORD "\n" $0 }
END { print RECORD }

当然，除了简单地打印记录之外，您可能还想做其他事情。

Answer 2

您可以使用awk执行此操作，以使用域信息获取每个数据库属性的条目。这是要求吗？

putSampleR :: Handler ()
putSampleR = do
    Args{..} <- requireJsonBody
    <balabalabala>
  where
    data Args = Args { a :: Int }
    instance FromJSON Args where

假设awk 'NR==nr{ next } NF==1{ nr=NR+1; dmn=$1; i=1; next } dmn"@"$1"@"i in a{ i++ } { a[dmn"@"$1"@"i]; b[dmn","i]=b[dmn","i]","$0 } END { for ( i in b) print i""b[i] }' file中没有空行。
