To display the contents of the file on the terminal, use the cat command:

$ cat copyme
firstfile

Now, we can use a basic invocation of the cp command to create a copiedme file from the original copyme file:

$ cp copyme copiedme

Upon investigation, we find that they are truly separate files; their inode numbers are different:

$ ls -i copyme copiedme
  648284 copiedme   650704 copyme
