Write your reply.

assistant: Hi,
I have seen several of your messages and so far refrained from commenting
but I think you need to ask yourself whether you actually want to
understand. Linux is difficult to learn. It's not going to be handed to you
on a plate and if you keep sending pointless messages which just rubbish
linux, the programmers which have given their time to it and anybody else
who hasn't designed something to be up to your standards, then you won't get
very far. Nor will you get helpful answers to your queries in here.
If you don't like it don't use it.
As for the above:
file is a program which when run will attempt to find out what sort of file
the filename it is passed is.
The first line in the example (file /etc/hosts) runs the executable "file" on
the file hosts which is in the /etc directory.
File then looks at /etc/hosts and outputs the name of the file and then its
type.
That was one of your questions in case you had forgotten. You asked how to
keep track of what sort of file something was without extensions.
In other words:
When you want to find out what sort of file "abc" is you should type "file
abc" (without the quotes).
I hope that helps. Of course you could look up file in the manual.
I believe people have tried to tell you about the manpages before.
You need to type "man command" (without the quotes and where command is the
name of the command you want to know about)
So in this case type:
man file
To find out the syntax of the file command.
I hope that you will understand this and that it is useful to you.
bfn,
si.
