Adding man command

[dtruong33]

Proposal: Adding the man command to xv6

Scope:

• The command itself
• Man page library for commonly used commands and functions
• Display and formatting for the pages
• Functionality for scrolling and searching within the man pages

Implementation: The man command would first take in the user’s command line argument to find the requested man page. It would look for and read that page within the library. It displays the page and waits for further commands.

Files added

• Man.c: main implementation, including finding, reading, displaying, searching, etc
• Man: directory to store and retrieve the man pages
• Makefile: modify to recognize added files

I think this is a good idea. Last semester, we created a 'docs' directory with markdown files for commands, so perhaps you could read from those. The terminal functionality we have is quite limited so you may need to work around the limitations for this.

I can code review this. For ps, I added a markdown file to docs in support of this.
