Find the real flag among decoys
A directory tree has hidden folders and decoy flags. Use find to list dotfiles, then grep with a strict pattern so only the real flag matches.
Briefing
The challenge is the ~/challenge folder. Read README.txt for the flag format.
Files and folders whose names start with a dot are hidden from plain ls. find lists them. grep -r searches a tree, and -o -E with a tight pattern prints only exact matches.
