我想实现的是：

基本上，同一段落（会话）中的所有行都应连接"|"。然后应该添加回车符并连接下一段，依此类推；时间
到目前为止，我只能连接所有的行，但无法添加回车。。任何帮助都将不胜感激。非常感谢。
您可以使用以下awk脚本来完成此操作：
awk '{if ($0 ~ /^s*$/) {print line; line="";} else line=line $0 "|"}' file.txt
这是假设在段落结束后总是出现一个空行，和您的示例相同。
解释：
$0 ~ /^s*$/ - to check if line is completely blank or only has white spaces
if block executes when blank line appears. It prints line var and resets line to ""
else block is concatenating line variable with the current line of file and a pipe
这可能对您有用（尽管您的数据不清楚）：
sed '1{h;d};/^[123]?[0-9] [JFMASOND].. ..:..:....../{:a;x;s/s*n+/|/g;s/.$//p;d};H;$ba;d' file
