使用 awk 或 sed 连接具有模式的行

Question

我基本上想将查询的名称放在包含 SourceField 的每一行前面。

我试过这个串联方案

awk '/<\^Query/ && p{print p;p=""}{p=p $0}END{if(p) print p}' 

但这仅适用于我有多个源字段。发生这种情况时，它将所有行与 SourceField 连接起来：

Query: D Monthly Loan SourceField: LOAD-NO         SourceTable: MASTER SourceField: LO  

我的数据是：

Query: D Monthly Loan
    SourceField: LOAD-NO         SourceTable: MASTER
    SourceField: LO              SourceTable: MASTER
Query: D Monthly Loan
    SourceField: HI              SourceTable: MASTER2
QUERY: M FORBEARANCE_1
    SourceField: LOAN-NO         SourceTable: MASTER

我希望输出看起来像这样：

Query: D Monthly Loan SourceField: LOAD-NO         SourceTable: MASTER
Query: D Monthly Loan SourceField: LO              SourceTable: MASTER
Query: D Monthly Loan SourceField: HI              SourceTable: MASTER2
Query: M FORBEARANCE_1 SourceField: LOAN-NO        SourceTable: MASTER

Answer 1

$ awk '/^ +/{print q, $0; next} {q=$0}' file
Query: D Monthly Loan     SourceField: LOAD-NO         SourceTable: MASTER
Query: D Monthly Loan     SourceField: LO              SourceTable: MASTER
Query: D Monthly Loan     SourceField: HI              SourceTable: MASTER2
QUERY: M FORBEARANCE_1     SourceField: LOAN-NO         SourceTable: MASTER

或者如果您更喜欢这些格式中的任何一种（还有许多其他可能性！）：

$ awk 'sub(/^ +/,""){print q, $0; next} {q=$0}' file
Query: D Monthly Loan SourceField: LOAD-NO         SourceTable: MASTER
Query: D Monthly Loan SourceField: LO              SourceTable: MASTER
Query: D Monthly Loan SourceField: HI              SourceTable: MASTER2
QUERY: M FORBEARANCE_1 SourceField: LOAN-NO         SourceTable: MASTER

$ awk '/^ +/{$1=$1; print q, $0; next} {q=$0}' file
Query: D Monthly Loan SourceField: LOAD-NO SourceTable: MASTER
Query: D Monthly Loan SourceField: LO SourceTable: MASTER
Query: D Monthly Loan SourceField: HI SourceTable: MASTER2
QUERY: M FORBEARANCE_1 SourceField: LOAN-NO SourceTable: MASTER

$ awk -v OFS='\t' '/^ +/{$1=$1; print q, $0; next} {q=$0}' file
Query: D Monthly Loan   SourceField:    LOAD-NO SourceTable:    MASTER
Query: D Monthly Loan   SourceField:    LO      SourceTable:    MASTER
Query: D Monthly Loan   SourceField:    HI      SourceTable:    MASTER2
QUERY: M FORBEARANCE_1  SourceField:    LOAN-NO SourceTable:    MASTER
