View the files that are present in the current working directory using the ls command

bandit3@bandit:~$ ls
inhere

Move into the inhere/ directory. This can be done using the cd command

bandit3@bandit:~$ cd inhere/

View files that are in the directory using the ls command. Since we know the file is hidden we have to use the -a flag to view hidden files.

(For more information on the ls command and its various flags refer to man ls or ls --help )

bandit3@bandit:~/inhere$ ls -a
.  ..  .hidden

View the content of .hidden file using the cat command
