Searching recursively one string on windows OS

Question

I want to search one string e.g. "main" in my project on windows OS recursively. I searched that and find a solution Windows recursive grep command-line

I applied same with two different approach, and result is not as expected.

e.g. my approach

findstr /S "main" *.cpp

but when I choose

findstr /S "int main" *.cpp

I am not getting only my main function. What is the difference between these two approaches? is it wrong to provide strings with space?

Answer 1

This is because findstr takes a set of strings to search for. To actually match the string int main you have to use the /C option:

findstr /s /C:"int main" *.cpp

whereas your variant gives you every line with either int or main.
