ls lists funky names within M-x shell

ls lists funky names within M-x shell

[Doug Morris]

Anyone know why I get garbage with my file names (e.g. [01;34mcvs^[[0m)
using ls within the shell from M-x shell?  For example:

doug@gladyce ~/keep/dev/javagui/cmd $ ls -l
^[[0mtotal 24
-rwxr-xr-x  1 doug users 1196 Jan 25 15:40 ^[[01;32mcompile^[[0m
-rwxr-xr-x  1 doug users 1196 Jul  7  2003 ^[[01;32mcompile~^[[0m
drwxr-xr-x  3 doug users  176 Jul  7  2003 ^[[01;34mcvs^[[0m
-rwxr-xr-x  1 doug users  858 Jul  7  2003 ^[[01;32mdocument~^[[0m
-rwxr-xr-x  1 doug users  901 Jul  7  2003 ^[[01;32mjavadoc^[[0m
-rwxr-xr-x  1 doug users  309 Jul  7  2003 ^[[01;32mtest^[[0m
-rwxr-xr-x  1 doug users  272 Jul  7  2003 ^[[01;32mtest~^[[0m
^[[mdoug@gladyce ~/keep/dev/javagui/cmd $ 

Thanks,

Doug

They are SGR control codes that typically represent colours.  Your ls
program is presently configured to output these sequences -- you
probably see colourful listings using ls in an xterm or at the
console.  To display the colours within Emacs for all comint-based
modes including `shell-mode' you can add:

(ansi-color-for-comint-mode-on)

to your .emacs file.

If you would rather it only applied to `shell-mode' buffers then you
could add:

(add-hook 'shell-mode-hook 'ansi-color-for-comint-mode-on)

instead.

Actually, that's false.  It will delay turning
`ansi-color-for-comint-mode' on for all comint-based modes until
`shell-mode' is run.  Instead you could do:

(add-hook 'shell-mode-hook (lambda ()
                             (make-local-variable 'ansi-color-for-comint-mode)
                             (ansi-color-for-comint-mode-on)))

You could set in your ~/.emacs_<shell> file an alias for ls that  
invokes it without colorising its output, or you can make  
~/.emacs_<shell> to un-set an environment variable that makes ls  
colorise its output.

You should invoke M-x manual-entry RET ls RET in emacs to read about  
your system's actual ls implementation, and maybe do an M-x manual- 
entry RET <your shell> RET too.


This ls output colorisation can't work, IMO, inside an usual Emacs  
shell since its TERM value is set to dumb. It might work better  
inside the more complete terminal emulation (M-x term <RET>), but  
could be you need a modern implementation of ANSI to see colours from  
ls in the running shell, i.e. GNU Emacs 22 from CVS.
