awk过滤掉段落

Question

我有一个普通的 txt 文件，其中包含大约 15-40 行的段落，每个段落与 previous/next 一个有 3 个空行的段落分开，我想打印出所有段落包含字符串 "sasi89".

Answer 1

awk 来拯救

awk 'BEGIN{ORS=RS="\n\n\n"} /sasi89/'

这将保留段落之间的 3 个空行。如果要标准化为单个空行，请删除 ORS= 或简单地

awk -v RS="\n\n\n" '/sasi89/'

Answer 2

您可以在 "paragraph mode" 中使用 awk（参见 https://www.gnu.org/software/gawk/manual/html_node/Multiple-Line.html），方法是将 RS 设置为空字符串：

awk -v RS= '/sasi89/' file

以上假定您的文件中除了段落之间的空白行之外没有其他空白行。
