windows下的类似linux下的grep命令--findstr

windows下的类似linux下的grep命令——findstr
经常用linux下的grep命令，比如：
netstat -an|grep 1521
其实windows下也有一个类似的命令findstr,比如：
C:\Windows\system32>netstat -an|findstr 1521

当然windows下还有一个find命令，比如：
C:\Windows\system32>netstat -an|find "1521"
TCP 0.0.0.0:1521 0.0.0.0:0 LISTENING
TCP 192.168.1.100:1521 192.168.1.100:49686 ESTABLISHED

TCP 192.168.1.100:49753 192.168.1.100:1521 ESTABLISHED
TCP [::]:1521 [::]:0 LISTENING
两个命令的区别是find需要用引号引起来。
