• Consider adding unit tests to cover the port number validation logic, including cases for empty, non-numeric, and out-of-range inputs.

if (port.empty() || !std::all_of(port.begin(), port.end(), ::isdigit) || std::stoi(port) < 1 || std::stoi(port) > 65535) {

• Ensure that the new 'cd' command and its associated current directory update are fully covered by tests to verify correct behavior on success.

• [nitpick] Consider caching the result of std::stoi(port) in a local variable to avoid duplicating the conversion call, which improves both performance and consistency.

if (port.empty() || !std::all_of(port.begin(), port.end(), ::isdigit) || std::stoi(port) < 1 || std::stoi(port) > 65535) {

Can you please also implement the main.cpp file on the client side, and modify the cmake to make an executable from this?

[DarkPhoenix42]

Why am I asked to enter server-ip even after I provide it using command line argument?

[DarkPhoenix42]

Also, can you please remove the redundant semicolons?
