Example Search for strings in an executable file

Prepare an executable file, and perform a string search on it.
The source code of the executable to be searched is as follows.

ConsoleApplication1.cpp

#include <iostream>
int main()
{
    std::cout << "Hello World!" << std::endl;
}

Create an executable file (exe) and run string against this executable file.
In the example, the string “Hello World!” is extracted after searching for more than the specified number of characters.

> strings.exe -nobanner -n 12 .\ConsoleApplication1.exe | ? {$_ -eq "Hello World!"}
Hello World!

We were able to find the string Hello World!

You can also use findstr to find the string.

> strings.exe -nobanner -n 12 .\ConsoleApplication1.exe | findstr /i "Hello World!"
Hello World!
