build

requires .NET 8+, windows only.

dotnet build -c Release
dotnet run -- list

or grab the exe from releases and drop it somewhere on your PATH.

notes

• modules and strings may need admin for protected processes
• strings caps at 2000 results — raise minlen to cut the noise (default 6, try 10-12 for real signal)
• watch polls at 250ms, low enough to catch most launches
• partial name matching: phantom info note finds notepad
• multiple matches: picks the first by PID, warns you

---

testing

built and tested against real processes on windows 10. commands verified:

• list — ran against a live system, output confirmed
• info — tested on explorer (105 threads), correct field values
• modules — tested on explorer, ntdll/kernel32 base addresses verified
• strings — scanned chrome memory, real strings returned (SQL histogram names, URLs, DLL paths)
• watch — logic tested, not sat through a full process start/exit cycle

what i can't guarantee: edge cases on processes with unusual access restrictions, very large processes running out of memory buffers, or behavior on windows 11 / windows server. the P/Invoke signatures are correct but real-world use will surface things a code walkthrough won't.
