我有stdout很多看起来像这样的文本块：
% QUESTION
Who played drums for The Beatles?
% QUESTION
Who played
guitar
for The Beatles?
% QUESTION
Who played
bass for The Beatles
?
这里的想法是将文件分成“块”，其中每个块都以 line 开头% QUESTION。我想编写一个脚本来打印此数据的第 n 个块。
例如，发行nthchunk 3应打印
Who played
bass for The Beatles
?
我怎么能去做这件事？
对于awk支持正则表达式作为其记录分隔符 ( RS)的实现，例如 GNU awk，您可以执行以下操作：
awk -v n=3 -v RS='(\n+|^)% QUESTION\n' 'NR == n+1 {print; exit}' < questions.txt
