solc, the solidity compiler commandline interface
Version: 0.5.7+commit.6da8b019.Linux.g++

1. In the root directory, compile the World contract described contracts/World.sol with bytecodes output to current directory

   solc --bin --optimize contracts/World.sol -o .

This should give us two files Hello.bin and World.bin containing bytecodes for the respective contracts

2. Change into the contracts folder, and compile the World.sol with bytecodes output to that folder

   solc --bin --optimize World.sol -o .

This should also give us two files Hello.bin and World.bin containing bytecodes for the respective contracts

Compare the World.bin and contracts/World.bin with diff would tell us difference

The same contract manifest should produce the same bytecodes
