In this challenge the password is stored in the only human readable file in the inhere directory.
Entering the directory we are greeted with 10 files named -file0<number>. To find this we can use the file command which will return the filetype.
file ./-file0<number>
To make this faster, we can use the wildcard character ?, which the shell interprets as "any single chacracter". This allows us to check all of our files in one command.
file ./-file0*
That command returns this:
As we can see there is one file that is made up of ASCII text.
Opening this file reveals the password: lrIWWI6bB37kxfiCQZqUdOIYfr6eEeqR
