Answer 1

在awk中，由于您可以查看特定列，而不是更一般的grep如何检查第3列是“A”而第4列是从0到5循环？那将是

awk 'BEGIN{seek=0} $3=="A" && $4==seek {print; seek +=1; if (seek>5) seek=0}' file.txt

Answer 2

awk '$3=="A" && $4==s {A[s]=$0; s++; if (s<6) next;}
      s==6 {for(i=0; i in A; i++) print A[i]; s=0; next;}
      {s=0}' input.txt

输出：
