In windows, the grep command like in linux -- findstr

In windows, similar to the grep command in linux -- findstr often uses the grep command in linux, such as netstat-an | grep 1521. In fact, there is a similar command findstr in windows, such: c: \ Windows \ system32> netstat-an | findstr 1521 TCP 0.0.0.0: 1521 0.0.0.0: 0 LISTENINGTCP 192.168.1.100: 1521 192.168.1.100: 49686 ESTABLISHEDTCP 192.168.1.100: 1521 192.168.1.100: 49701 192.168.1.100: 1521 192.168.1.100: 49702 ESTABLISHEDTCP 192.168.1.100: 1521 192.168.1.100: 49706 ESTABLISHE DTCP 192.168.1.100: 1521 192.168.1.100: 49707 255.tcp 192.168.1.100: 1521 192.168.1.100: 49753 ESTABLISHEDTCP 192.168.1.100: 49686 192.168.1.100: 1521 ESTABLISHEDTCP 192.168.1.100: 49701 192.168.1.100: 1521 255.192.168.1.100: 49702 192.168.1.100: 1521 255.192.168.1.100: 49706 192.168.1.100: 1521 ESTABLISHEDTCP 192.168.1.100: 49707 192.168.1.100: 1521 ESTABLISHEDTCP 192.168.1.100: 49 753 192.168.1.100: 1521 ESTABLISHEDTCP [:]: 1521 [:]: 0 LISTENING www.2cto.com, of course, there is a find command in windows, such as: C: \ Windows \ system32> netstat-an | find "1521" TCP 0.0.0.0: 1521 0.0.0.0: 0 LISTENINGTCP 192.168.1.100: 1521 192.168.1.100: 49686 ESTABLISHEDTCP 192.168.1.100: 1521 192.168.1.100: 49701 ESTABLISHEDTCP 192.168.1.100: 1521 192.168.1.100: 49702 ESTABLISHEDTCP 192.168.1.100: 1521 192.168.1.100: 49706 ESTABLISHEDTCP 192.168.1.100: 1521 192.168.1.100: 49707 protocol TCP 192.168.1.100: 1521 192.168.1.100: 49753 ESTABLISHEDTCP 192.168.1.100: 49686 192.168.1.100: 1521 protocol 192.168.1.100: 49701 192.168.1.100: 1521 protocol 192.168.1.100: 49702 protocol 192.168.1.100: 1521 protocol 192.168.1.100: 49706 192.168.1.100: 1521 ESTABLISHEDTCP 192.168.1.100: 49707 192.168.1.100: 1521 ESTABLISHEDTCP 192.168.1.100: 49753 192.168.1.100: 1521 established tcp [:]: 1521 [:]: 0 LISTENING the difference between the two commands is that find needs to be enclosed by quotation marks.
