That depends on your mailer. But you seem to have done it for this message.
Have you changed something? Your email is easier to read than it used to be.

Again, you seem to be doing so already. Normally a mailer will make
these markers for you. Then you just walk down the message, removing
irrelevant stuff and replying to the other parts as necessary.

Yes.

Yes, but normally you would have a directory of your own for this purpose.

| What directory should I use for own files?

Normally, $HOME/bin. So:

- log in
- type "pwd" to check that you are in you home directory
- type "mkdir bin" to create a directory called "bin" in your home
directory

Then you need to put $HOME/bin into your $PATH.

You can do this by running the command:

PATH=$PATH:$HOME/bin
export PATH

That does it only for the shell you ran it in.

To make it permanent, you would put that same command in your
.bash_profile (if your login shell is bash, which is probable). The
command:

echo $SHELL

should tell you which shell you have.

Yes.

Yes. So there would be a /home/user1 for user1's files, and a
/home/user2 for user2's files.
