AWK:如何抑制默认打印

Question

AWK:如何禁止默认打印 以下 awk if 语句总是打印 $0。如何阻止它这样做

    ( nodeComplete && count ) 
    {

        #print $0
        #print count;

        for (i = 0; i < count; i++) {print array1[i];};

        nodeComplete=0;
        count=0;
    }

Answer 1

欢迎使用 SO，尝试更改大括号 { 的位置，如果有帮助请告诉我。

( nodeComplete && count ){
  #print $0
  #print count;
  for (i = 0; i < count; i++) {print array1[i];};
  nodeComplete=0;
  count=0;
}

上述变化的解释:

logic behind this is simple { next to condition means coming statements should be executed as per condition. If you put them in next line then it will all together a different set of block and condition will be a different block. So if condition is TRUE then it will print complete line since { is altogether a separate block.
