一种使用方式GNU sed：

sed -n 'H; ${ x; s/\n//; s/\n //g; p}' file.txt

结果：

这可能对您有用（GNU sed）：

sed ':a;N;s/\n //;ta;P;D' file

打开两行窗口。删除一个换行符后跟一个空格并重复该模式失败。最后打印第一行，如果模式空间中还有第二行，重复。

使用 sed 的一种方法：

sed ':a;$!N;s/\n //;ta'  file

sed 加入（N）除最后一行（$！）之外的每一行。加入后，将删除后跟空格（\n）的换行符。'ta' 是循环到分支 'a' 直到替换失败。

如果 的唯一出现\n，即换行符后跟空格，是需要加入行的地方，你可以这样使用bbe：

<file bbe -e 's/\n //'

另一种解决方案：

awk 'ORS="";!/home/{$1=$1; print}{RS="\n"}END{print "\n" $0 "\n"}' file
