Terminal Guide
Useful commands:
cd
The command 'cd' changes the focus of the directory to the specified location. Example: 'cd Downloads/folder/'. To reset back to the original directory, type in 'cd ~'.
cat
The cat command inserts a file into another one, hiding it. Here's how to do it in several steps:
First, put two files in a directory. One of them should be a zip file, and the other one should be the one that hides the archive.
Next, open terminal and change the focus of the directory using the 'cd' command: 'cd Documents/example\ folder/'.
Finally, you want to type in the cat command: 'cat example.png archive.zip > result.png'. The 'example.png' file represents the image or file you want to hide the other file in, 'archive.zip' represents the file you are hiding, 'result.png' is the result that comes from the hiding of the archive.
Note: To open your hidden file, simply type in the 'unzip' command: 'unzip result.png'. Make sure the focus is in the specified directory.
passwd
This command simply changes the user password.
