In ubuntu we can use the following code to check the time

time ./a.out < in 
time ./generator | ./a

Using generator

#!/bin/bash
g++ -o gen gen.cpp
g++ -o main main.cpp
g++ -o brute brute.cpp
for((i = 1;;++i));do
    echo $i
    ./gen $i > inputt
    diff -w <(./main < inputt) <(./brute < inputt) || break
done

To copy a single file to multiple Files

echo a.cpp b.cpp d.cpp | xargs -n 1 cp template.cpp
