ls

cat instructions-to-2of3.txt 

# output
# Next, go to the root of all things, more succinctly `/`

cd /
ls

# output
# 2of3.flag.txt  dev   instructions-to-3of3.txt ...

Let’s print the second part of the flag -

cat 2of3.flag.txt

# output
# 0ut_0f_\/\/4t3r_

Get the third and final clue and follow it -

cat instructions-to-3of3.txt

# Lastly, ctf-player, go home... more succinctly `~`

cd ~
ls

# output
# 3of3.flag.txt  drop-in

Print the last part of the flag -

cat 3of3.flag.txt
