Grep 并合并文件的两个时间戳行之间的行 - Unix

我正在尝试从日志文件中 grep 特定模式的行Logfile.txt并将输出重定向到新的文本文件1.txt。日志文件^M中包含一些控制字符，并且这些行将在时间戳行之间可用，因此我尝试将所有这些多行合并为单行，并尝试将其附加到预期结果中，如果前一行包含Execute模式它。但无法按预期获得

日志文件.txt

代码 - 我的发现

egrep -wah 'Setting the session:|Checking the line|Completed|Execute|Exiting' Logfile.txt > 1.txt

答案1

尝试

awk '{X = $0; while (/\r$/) {getline; if (! /^[0-9]/) X = X $0}; gsub (/\r/, "", X); print X} 1 ' file

当遇到 ^M 字符时，它会循环读取并添加更多行，直到读取日期，然后打印整行。
