Task

The password for the next level is stored in a file somewhere under the inhere directory and has all of the following properties: human-readable, 1033 bytes in size, not executable.

Solution

Let's see the files present:

bandit5@bandit:~$ ls
inhere
bandit5@bandit:~$ cd inhere/
bandit5@bandit:~/inhere$ ls
maybehere00  maybehere03  maybehere06  maybehere09  maybehere12  maybehere15  maybehere18
maybehere01  maybehere04  maybehere07  maybehere10  maybehere13  maybehere16  maybehere19
maybehere02  maybehere05  maybehere08  maybehere11  maybehere14  maybehere17

Find the entire directory with size parameter set to 1033 bytes.

bandit5@bandit:~$ find . -size 1033c
./inhere/maybehere07/.file2

(bytes is represented as c).

We found just one file that satisfies one of the condition. Then pipe it to file which checks for dashed file using -- and then pipe it to grep for ASCII text.
Just to verify the rest the command is:

bandit5@bandit:~$  find . -size 1033c ! -executable - exec file '{}' \; | grep "ASCII"
./inhere/maybehere07/.file2

One liner: find . -size 1033c | xargs file -- * | grep "ASCII" | cut -d ":" -f1 | xargs cat
