^[[32;1mvytas@clt-84-32-234-17:~>^[[0m
with those unnesecery characters in the beginning and the end. im using
22.1.1
could anyone tell me what the problem could be?

Yes, I can tell you ;)
The [32, etc are control characters that indicate colors. Try turning
them off in your shell's rc file or use "M-x ansi-term" to see the
colors. Or learn to use Dired, which replaces much shell
functionality (I hardly use a real command line now).

Your bash prompt is creating ANSI Esc sequences to set colours or
effects.
In GNU Emacs 22 you can invoke
ansi-color-for-comint-mode-on
to make *shell* buffer interpret certain ANSI Esc sequences (you can
also put it into an init file). You can use a file ~/.emacs_<shell
interpreter's name> to adjust some settings for *shell* buffer. You
would need to use that shell interpreter's syntax. For example, if
your login shell is bash and you put
PS1="$ "
into ~/.emacs_bash than you'll have a much shorter and monochrome
prompt ...

No need to resort to `ansi-term', which is a full terminal-emulator.
You can have shell mode interpret those codes using
`ansi-color-for-comint-mode-on'.

What's the difference between shell-mode and a terminal emulator? I
had trouble getting used to shell-mode, so I refused to learn much
about it.

`shell-mode' is a mode for running a command interpreter (in most
cases a shell) in an Emacs buffer. All Emacs commands are available
and work as expected: pressing "C-p" will move the cursor to the
previous line, "C-w" will kill the region etc.
In the terminal emulator you can run *any* terminal program, be it a
shell, a mailer or even VI (forgive the heresy!). How the keybindings
behave is dictated by the program running in the terminal.
If you want to run a terminal program like "trn", "less" or "lynx" you
have no option but `ansi-term'. For running a command interpreter
`shell-mode' offers you the best of both worlds: you can run your shell
*and* have all Emacs text manipulation facilities at your disposal.
Note that in shell-mode the command line editing provided by the your
shell (e.g. "readline") is not available; "shell-mode" provides it's
own command line editing facilities.

I did that and now I get nicely colored output, but still there are some
control characters left and each command is printed twice.
,----

| > echo "Hello, test!" <== After my RET the line gets repeated...

`----
Do you know what ^[ and ^G are for control chars and how I can get rid
of them?
If I do the same in an xterm I get
,----
| > echo "Hallo, test..."
| Hallo, test...
`----
without any coloring. So what's confusing emacs here?

Those are my two reasons for preferring ansi-term. I sometimes run
lynx in ansi-term. When i'm using a terminal, I make extensive use of
command-line editing, so I didnt' like having the Emacs inter-line
commands work in the buffer instead of on the command line (ironic
though that is).

It becomes interpreted as prompt. Check comint-prompt-regexp and
shell-prompt-pattern.

Again, it seems to be kept for the prompt?

ESC\x05 and BELL. Maybe you should check which echo you are using, what
is set for it, and what else is set for the shell interpreter running
in *shell* buffer.
After all: are you using GNU Emacs 22? At some time GNU Emacs 21.3.50
from CVS learned this and GNU Emacs 22 inherited it. Earlier versions
don't work as described.

,----[ C-h v comint-prompt-regexp RET ]
| comint-prompt-regexp is a variable defined in `comint.el'.
| Its value is
| "^[^#$%>\n]*[#$%>] *"
| Local in buffer *shell*; global value is "^"
|
| Documentation:
| Regexp to recognize prompts in the inferior process.
| Defaults to "^", the null string at BOL.
|
| This variable is only used if the variable
| `comint-use-prompt-regexp' is non-nil.
`----
By default `comint-use-prompt-regexp' is nil in *shell*. I've set it to
t, but that doesn't change things.
,----[ C-h v shell-prompt-pattern RET ]
| shell-prompt-pattern is a variable defined in `shell.el'.
| Its value is
| "^[^#$%>\n]*[#$%>] *"
`----
So it seems that `comint-prompt-regexp' is set to `shell-prompt-pattern'
in shell-mode.
And this regexp matches my prompt. It's only a simple "> " when TERM is
set to dumb.
(string-match shell-prompt-pattern "> ") == C-x C-e ==> 0

I have set
EMACS=t
and I am using a regular shell, tcsh. In my *shell* buffer the prompt
is found and fontified in bold and some colour.
You could make tests without loading any customisation and with a
different login shell ...
Could be it's worth to read the documentation on fish a few times
during this so-called summer. When I do this on tcsh I get every time
surprised ...

Yes, with `shell-file-name' set to /usr/bash it works, too.

Yes, I'll do that and if I don't find anything I'll ask on the fish
