基本上我需要打印2行然后删除两行,依此类推.
awk 'BEGIN {count = 0} if(count == 4){count = 0} else if(count <= 1) {print,count++} else {count++}' f4
我收到语法错误.
要么
awk '{count = 0; if(count == 4)count = 0; else if(count <= 1) print count++; else count++;}' f4
它打印全部为零.
我也试过了
awk 'NR%3 && NR%4' f4
这是接近但3和4的倍数不打印.
谢谢
编辑:GOT IT!
awk 'BEGIN{count = 0};{ if(count == 3)count = 0; else if(count <= 1) {print; count=count+1;} else count=count+1;}' f4
我无法让Javascript工作.这三个都在同一个文件夹中.Chrome也需要一段时间才能打开,但Firefox是即时的.谢谢.
