If you don't have any man pages installed (often the case in docker containers as they strive to be as minimal as possible) creating the needed folder might help you further:. mkdir -p /usr/share/man/man1 This is due to the fact that it assumes said folder to usually be there, but doesn't take care of creating it if the folder is missing.
What is problem solving? Problem solving is a process of finding and implementing a solution to a challenge or obstacle. In most contexts, this means going through a problem solving process that begins with identifying the issue, exploring its root causes, ideating and refining possible solutions before implementing and measuring the …

Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by …
