escape characters in emacs20 shell mode

escape characters in emacs20 shell mode

[Nimar Arora]

Hi,

I'm running emacs20 on a Linux (Debian - Woody/stable)
virtual console. When I enter an emacs shell and try
to execute some command - like 'ls' - the output
contains a whole of junk - [[0m etc. These look like
the escape characters which can control the display
attributes on some terminals. I don't understand why
I'm getting these. I don't even have a .emacs file
yet, so I haven't changed the default configuration.

I tried, 'E-x shell-strip-ctrl-m' but to no avail. I
also tried to lookup the info on Emacs shell mode to
see if Debian has created some funky shell mode but
couldn't find anything.

Thanks,

Nimar

You probably have an alias on ls like alias='ls --color=auto'. These
ares color codes. Unalias ls and it should work as you want.

I still don't understand why auto-color tries to color on a dumb
terminal (same here). Probably a wrong terminfo/termcap definition.

Is $TERM really `dumb' in an Emacs shell?

Using M-x shell, yes (for me under GNU Emacs 21.2.1), using eshell
TERM is not defined.

Ah what a neat trick. I have been putting up with no colors for years
because I thought it was something that didn't work.

Now would it be possible to pass the tab command directly to the
shell? Now that bash has programmable tab completion I would like to
use it withing emacs. I would like to have the same behavior when I am
running bash in a console and when it's running in emacs.

I vaguely remember that somebody posted something like this for
tcsh.  Maybe it was called tcsh-completion.el.  But it was many years
ago, so I don't remember.

piping

[Joe Corneli]

Hello --

does anyone know if it is possible to pipe a file to a running XEmacs 
and have
the file open in a new buffer?  This might be more of a shell question 
than
an emacs question, but I don't know the protocol and am curious.

Thanks,

Joe Corneli

PS.  This is for those times when I can't type C-x C-f from within 
XEmacs...

Use (server-start) in the Emacs process, and "emacsclient" from the shell.
