Bashcrawl is a series of challenges revolving around the bashcrawl game which purpose is to teach the basics of using a POSIX (Linux, BSD, UNIX) terminal.
Having used Linux for a few years I did not need to learn how to use the command line and didn’t have time either as I had a CTF to win.
So I decided to use alternate ways of finding the answers to the challenges. This will mostly resolve around using grep to find where is the part related to the current challenge.
If you want to try this yourself just clone the repo.
Without further ado lets get started.
Bashcrawl 1 Link to heading
Where are you ?
This is an easy one and we simply need to give the name of the starting directory which is entrance.
Bashcrawl 2 Link to heading
Where does the portal lead ?
We are supposed to play the game until we encounter a portal (which is creating a link using ln) and give the name of the directory we end up in.
But this is to long I don’t have time to play this game so :
$ grep -r "portal"
cellar/armoury/chamber/spell: echo "a portal that will allow you to walk through"
cellar/armoury/chamber/spell: echo "ln -f -s `pwd`/../../../chapel/courtyard/aviary/hall portal"
.scrap:# ln -s ../../../../.rift portal
There are two places where a portal is mentionned in the .scrap file and in a file in the chamber . As a lazy person I of course start by the one I am already in, the portal that lead to the rift. Wrong flag, ok then it’s the other one. I try the other one and it’s correct, the flag is spell.
Bashcrawl 3-6 Link to heading
I am not going to give you all the solutions you will have to finish by yourself 😉
