grep遵循文件模式的連續行的具體數量

使用awk僅抽取包含「A 0」，「A 1」，「A 2」，「A 3」的連續行的是否可行？，「A 4」，並從具有如下結構的文件「A 5」：grep遵循文件模式的連續行的具體數量

一切皆有可能** **。你有沒有嘗試過幾乎沒有用的東西？顯示你的嘗試，並明確你需要幫助。 –

在awk，因爲你可以看看具體的專欄，而不是更一般的grep che怎麼樣確定第3列是「A」，第4列是從0到5循環？這將是

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

即使將第二行更改爲「A0」，也會打印第一行 – Ashkan

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
