[Tomcat-42]

I was able to find the password for this level using the following one-liner:

find inhere -type f -exec file {} + | grep ASCII | awk '{ print $1 }' | tr -d ':' | xargs cat

First, I find the text file, using find and grep, then I extract the filename using awk and tr and finally prints the content using xargs and cat.

file inhere/* | grep A | cut -d: -f1 | xargs cat

ngl, you kinda dump, check it out and deal with it. 😎

my solution for this one:

du -a -b  | grep 1033

[Mulling]

Very bloated!

find . -size 1033c -type f -perm -000 | xargs cat

[Tomcat-42]

Dear commrades,

Yours Solutions are very bloated, the following is more elegant:

find ./inhere/ -type f -size 1033c ! -executable| xargs file | grep text | awk '{ print $1 }' | tr -d ':' | xargs cat

Yours Trully, Pablo (the Toxic Tuna Overlord).
