Question

如果我有一个文本文件，其记录以//分隔，标题包含单行或多行内容，例如

SOMETHING (single line content)
ATHING Lorem (single line content) 
THETHING (single line content)
THING (multi-line content)
ANOTHERTHING (single line content)
//
SOMETHING (single line content)
ATHING Lorem (single line content) 
THETHING (single line content)
THING (multi-line content)
ANOTHERTHING (single line content)

我想要打印： 1）匹配“ATHING”的行和2）匹配以THING开头直到下一个标题的多行行，以便我最终得到这个输出：

ATHING content, THING content (multi-line concatenated to single line)
ATHING content, THING content (multi-line concatenated to single line)

Answer 1

awk 解决方案：

示例testfile内容：

SOMETHING (single line content)
ATHING Lorem (single line content) 
THETHING (single line content)
THING (multi-line content)
some tetx
sdsdf text
ANOTHERTHING (single line content)
//
SOMETHING (single line content)
ATHING Lorem (single line content) 
THETHING (single line content)
THING (multi-line content)
text 
text
ANOTHERTHING (single line content)

工作：

awk -v th="^THING" '/^ATHING/{ printf "%s,",$0 }
       $0~th{ f=1 }
       f{ if ($0~/^[A-Z]/ && $0!~th){ f=0; print "" } else printf " %s",$0; }' testfile

输出：

ATHING Lorem (single line content) , THING (multi-line content) some tetx sdsdf text
ATHING Lorem (single line content) , THING (multi-line content) text  text

Answer 2

BEGIN                   { OFS = ", " }

/^\/\// && line         { print line;
                          line = "";
                          getline;
                          next          }

NR > 1 && line          { line = line OFS $0 }
NR > 1 && !line         { line = $0 }

END                     { print line }

此awk脚本将在line中构建每个输出行，并在适当时输出。

BEGIN块设置用于连接线的分隔符。
当找到//分隔符并且在line中组装了一条线时，第二个块执行。它打印该行并重置该变量。它还跳过下一行输入（SOMETHING输入行），然后从脚本开始后继续下一个输入行。
使用NR > 1，我们会跳过最初的SOMETHING行。如果line包含某些内容，则会将当前行附加到其中，否则我们只需将line设置为当前输入行。
最后，输出为最终输入块组装的线。

对于给定的数据，这会产生：

$ awk -f script.awk file.in
ATHING Lorem (single line content), THETHING (single line content), THING (multi-line content), ANOTHERTHING (single line content)
ATHING Lorem (single line content), THETHING (single line content), THING (multi-line content), ANOTHERTHING (single line content)

使用awk将匹配的行映射到逗号分隔列的文本到csv
