How to search text written in cmd

Question

I want to find the necessary attribute through the command's help output. How to do it? Output like this: help output

Answer 1

Let's say you are looking for the /H switch:

Program.exe /? |find /i "/h"

Program.exe --help |find /i "/H"

That should only show you the line where there is an "/H" occurrence.

Some programas also accept:

program.exe /h /? program.exe /h --help

Answer 2

Let's say I want to find the flags available for the a command within the terminal. For brevity, let's pick "replace".

You can type either of the following:

help replace | findstr "\/" 
help replace | find "/"

to find all lines that have a forward slash (backslash is used to escape the forward slash).

Below an example with findstr and regex to filter network connections:

 netstat -n | findstr -r "127.*"

Both find and findstr serve the same purpose but findstr is newer and supports regex. To learn about the difference, you can check this answer in SuperUser.
