Hi everyone,

I just want to know, what command is command prompt able to check which port number is available to use in my PC? or is there any software to check port number?. Thx

It's interesting, I haven't heard any ways to check this from batch file without using specifically created executable which cheks it, but I guess that you could grep netstat's output for interesting info.

You can check which port numbers ARE IN USE by using netstat and its various commands.

To use it, open up cmd.exe and type in netstat. If you want other commands, type netstat /?.
