file-finder is a simple C++ program that searches the provided directory for files with one of the substrings in their name.
file-finder <dir> <substring1> [<substring2> [<substring3>]...]
Type dump during execution to force any matches found to dump to the console. Type exit to quit the search.
file-finder spawns a thread to service each substring. The main thread recursively iterates through the specified directory in a breadth-first strategy. File names are added to the substring worker thread work queues. If a file name contains the substring, it is added to a buffer that dumps to the console every second.
clang++ --std=c++20 *.cpp -o file-finder
