shell - 有没有办法将这种模式与 shell 或 sed 匹配？

Question

我有一个具有以下输出的文件:

BP 0 test:
    case    id          Name            
    ======  ========  =================
         0        82  a_case-2-0-0      

BP 1 test:
    case    id          Name            
    ======  ========  =================
         0        86  a_case-2-1-0      

BP 2 test:
    case    id          Name            
    ======  ========  =================


BP 3 test:
    case    id          Name            
    ======  ========  =================
         0        93  a_case-2-3-0 

所以，只有“BP 0,1,3”有内容，所以我想要的是，是否可以仅转储“BP 0 test”、“BP 1 test”和“BP 3 test”，只想忽略“BP 2 测试'，因为没有测试用例。

谢谢你的帮助。

$ awk -F'\n' -v RS='' -v ORS='\n\n' 'NF>3' input.txt
BP 0 test:
    case    id          Name
    ======  ========  =================
         0        82  a_case-2-0-0

BP 1 test:
    case    id          Name
    ======  ========  =================
         0        86  a_case-2-1-0

BP 3 test:
    case    id          Name
    ======  ========  =================
         0        93  a_case-2-3-0
