显示$5==10||$9>22880 $5等于10或者$9>22880的行

10 22866
14 22882
显示$5>10&&$9>22880 $5大于10并且$9>22880的行
[oracle@bys3 ~]$ cat awktest.log |awk -F'[,= :]' '$5>10&&$9>22880 {print $5"\t" $9}'
14 22882
显示$5!=10 $5!=11 不等于10并且不等于11的行

如果print ($5 > 12 ? 这里如果判断$5 > 12是否为真，真则显示冒号前的值，如果不为真，则显示冒号后值
[oracle@bys3 ~]$ cat awktest.log |awk -F'[,= :]' '{print ($5 > 12 ? "ok \t"$5: "error\t"$5)}'
