一行野郎:1秒おきにportを確認(コマンド繰り返し)

Posted at

###効果
1秒おきにportを確認。
コマンド繰り返しなので、別にportでなくてもよいけれど。

###一行野郎
while true; do netstat -a | grep "ssh"; sleep 1s; done;
netstat の所と grep の所を変えれば、いくらでも応用できて便利。
sleep 1 はお好みで。
while true; do netstat -a | grep "ssh" |tee -a hoge.log; sleep 1s; done;
保存するなら tee をはさんでもいい。

###必要な物

  • bash
  • netstat
  • grep
