No it isn't. You don't technically need linux for this one, either. As for the resuling answer--I created the file layout shown in it and ran the commands to make sure they worked as they should. Which part in particular are you saying is nonsense?

Edit: I just recreated the archive exactly as described and uploaded it here. My solution works perfectly on it. All non-archive files are blank; only README has any content.

If you use linux on the command line, you should know how to look things up. I'm constantly looking up how to do one thing or another.

NO COOKIES!

there's one common command around. PM me the command you're using on steam (I added you).

Edit: pipelines

Edit 2: I just realized the name of the painting might make that unclear. The pipe was a hint, not the name (yes, you can use them)

:D

Part 2 should be pretty simple. Others have done similar things in these forums. The program I named may help a bit.

Y631j is a hash. It may be used for a different reason though... I honestly don't remember which hash I used, so if you care to pm me on steam, lemme know what I need for a hint.

I'm not supposed to share hints, but I was stuck for a while in the same place. There was one key word in the question that I overlooked.

Feel free to ask me for help (help knowing what's wrong, not what to do next) in my groupchat, I'll stick around there while I'm online.

aptitude moo

I couldn't answer any of it off the top of my head either (well, except the first one because I've had to use it rather a lot). I would expect someone to maybe have some experience with reading manpages.

Look harder at the answer. People have done this before, though usually not at the end of a puzzle.

Feel free to join the chat for my group.

Hint for #2 if you're still stuck:

use -O.

Contact me in my groupchat, and I'll help you out.

Edit: See first 'edit' in the main post :P

Thanks :)

Post-Quiz:

The image contained a CPIO file that contained a file saying simply xAsf0. You actually could get this from winrar if you used the viewer.

This referred you to this forum post, which told you that string you're looking for is "eLqfM." Or is it?

This in turn meant that the giveaway (which was for bastion) was located here, giveaway hash eLqfM.
