sed - 使用 sed/grep/awk 删除所有内容直到第一个空行

Question

谁能帮我弄清楚如何做到这一点，将不胜感激。

例子

block of            //delete
non-important text  //delete

important text      //keep
more important text //keep

Answer 1

sed '1,/^$/d' file

或者

awk '!$0{f=1;next}f{print}' file

输出

$ sed '1,/^$/d' <<< $'block of\nnon-important text\n\nimportant text\nmore important text'
important text
more important text

$ awk '!$0{f=1;next}f{print}' <<< $'block of\nnon-important text\n\nimportant text\nmore important text'
important text
more important text
