Level 4 → 5

Level Goal

The password for the next level is stored in the only human-readable file in the inhere directory. Tip: if your terminal is messed up, try the reset command.

Write-Up

1. Navigate to the inhere directory:

ls
cd inhere

1. Identify the human-readable file:

for i in $(ls); do file -i "./$i"; done;

This reveals ./-file07 as the only text/plain file.

• for i in $(ls): Loops through each file in the current directory

• do: Starts the loop body

• file -i: Runs the file command to each file, using ./ to handle filenames starting with -

• done: Ends the loop

• Overall: Identifies the file type of every file in the directory.

1. Display the content of the identified file:

cat ./-file07

The retrieved password: 4oQYVPkxZOOEOO5pTW81FB8j8lxXGUQw

1. Access the next level:

ssh [e-mail] -p 2220

Enter the password when prompted.

Lessons Learned

• Scripting with loops can efficiently process multiple files

• The file command helps identify file types regardless of extension

• Using ./ is crucial when dealing with files that start with -
