Answer 2

'cat' will print the contents of a file to the screen, amongst other things depending on how you use it.
cat --help
or
man cat
You may want to pipe this to 'less' or 'more' if you're just trying to view the contents of the file.
Using cat on a binary file will give you a bunch of junk on the screen, in which case 'strings' will give you the readable data (strings) from the file.

Answer 3

The answer depends on what Operating System do you use. Windows and Linux shell scripting are both different. For most heavily secured companies, they often use Linux, mostly Red Hat, to protect their data as Linux is a lot more secure than Windows. So, I advice you to learn BOTH. They are not hard at all.

Answer 4

have you tried $ cat .help ?
