Is there a way to match such pattern with shell or sed?

sed, shell

Solution

$ 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

Problem

I have a file with following output: ``` 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 ``` so, only "BP 0,1,3" have content, so what I want is, is it possible to dump 'BP 0 test','BP 1 test' and 'BP 3 test' only, just want to ingore the 'BP 2 test' because of no test case. Thanks for your help.
