$ cat file1.txt

AIX
Solaris\
Unix\ 
Linux 
HPUX

我正在尝试将下一行追加到以反斜杠结尾的行，并将上述文件作为输入。

file.txt中的o / p如下所示，它是正确的

$ sed ':loop /\\$/N; s/\\\n */ /; tloop' file.txt

如果我再次使用file1.txt作为输入在行上方运行，则o / p不正确

$ sed ':loop /\\$/N; s/\\\n */ /; tloop' file1.txt
AIX

Linux 
HPUX

任何人都可以解释为什么file1.txt没有显示正确的o / p。

Answer 1

这可能适合你（GNU sed）：

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

这会占用换行符两侧的空格。

Answer 2

反斜杠后面有空格。尝试：

sed ':loop /\\ *$/N; s/\\ *\n */ /; tloop' file1.txt

尝试将下一行连接到sed中以反斜杠结尾的行
