In this puzzle box we will navigate around our terminal environment to retrieve the initial project files from /var/public/USER, and mingle with different commands, archives, and encoding systems while solving the puzzle. Some of the commands we will use are outlined in the toolbox below.

After retrieving setup.exe, we have to figure out what to do with the file. Extensions are deceiving as they don't necessarily dictate what the file type really is, which is a common theme in this puzzle. We'll have to be cautious of this.

• base64(1) - base64 encode/decode data and print to standard output

• chmod(1) - change file mode bits

• cp(1) - copy files and directories

• file(1) - determine file or data format

• mv(1) - move (rename) files

• tac(1) - concatenate and print files in reverse line-wise

• rev(1) - concatenate and print files in reverse character-wise

• tar(1) - an archiving utility

• uudecode(1) - decode an uuencoded file

• grep(1) - searching text within files

• sort -n - sort file numerically by start of each line
  • This will become especially useful towards the end of our puzzle box as it will allow us to sort our results which we will ultimately submit. You can pipe the results of this command into your *results* file directly.
