linux - 将每 n 行转置为一行

Question

我想把一堆 n 行合并成一行，不知道该怎么做。任何帮助表示赞赏。

一堆 11 个单词，然后是一个空行，然后是一堆 ll 个单词，然后是空白，就像...等等。

示例:

cat filename

hi
hello
how
are
you
i
am
fine
how
are
you

hi
how
is
she
doing
i 
have
not 
herd 
from
her

..
..

期望的输出:

cat newFile

hi hello how are you i am fine how are you 
hi how is she doing i have not heard from her 
..
..

Answer 1

通过 awk。

$ awk -v RS= '{gsub(/\n/, " ")}1' file
hi hello how are you i am fine how are you
hi how is she doing i  have not  herd  from her
