请问，如何用sed命令，将前面为空格的行与上一行合并？
谢谢。

WilliBhamlll

没发现前面为空格的行。猜一猜结果吧

1. sed ':a;N;s/\n\(^[^A-Z]\)/\1/;ta;P;D' file
   
2. H,-2.8371156948,-4.0601065366,-2.2585345957

1. awk '!/^[A-Z]/{print s""$0;s="";next}{s=s?s"\n"$0:$0}'

复制代码

sed 的暂时没想到，先上个awk的。

目测一下 合并前面为空格的行：

1. awk -vRS='' '{gsub(/$\n /," ")}1' urfile

谢谢大家的帮助，2，3，4，5楼的方法我都试了，都可以，谢谢大家。
实际上我有这样一个文件：

想通过shell编程实现：（1）将"\"替换成回车换行符 （2）将"#N"到"Versi"之间的内容保存。我写了一个shell，都不太满意，不能完全达到这个目的，还请大家帮忙。

1. tr "\\" "\n"  yourfile |sed -n '/#N/,/Versi/p'
