Hi all, When I issue asynchronous commands using shell-command, for example: M-! apt-get update & RET buffer *Async Command Output* is filled with ^M characters and the output is generally a mess. Apparently not all Emacsen behave in this way though. If you have a moment, could you perform a similar test and let us know if the same thing happens to you. Include the Emacs version number in your follow-up, and if it _does_ happen to you and you have a little more time, whether you consider it a feature or a bug? Your assistance is much appreciated.

I tried it with aptitude, it's the same. The process uses carriage-returns to display the progress `widget' this show up as '^M' in emacs buffer. Somehow this processes think they are running in a terminal, I think because asynchronous shell-commands are runnning/started in a shell. In a terminal : $ echo -e 'Hello\rWorld' $ World In emacs : M-! echo -e 'Hello\rWorld' & Hello ^MWorld Maybe a process-filter-function is the solution or pipe the command through the utility 'col', like M-! apt-get update | col & -ap
