tcsh$ cd ~
^[]0;sallred@calamity:/home/sallred^G
tcsh$ cd bin
^[]0;sallred@calamity:/home/sallred/bin^G
tcsh$

What is this cruft that is appearing before my prompt (or perhaps more appropriately, after my command) and how can I remove it?

    Perhaps too obvious, but are you setting prompt in your .cshrc (or equivalent) file? – glucas Nov 12 '14 at 15:27
  • @glucas set prompt "\ntcsh$ " This stuff only appears from within emacs. Additionally, there is nothing in my rc file that matches this general pattern: .*:.*@.*. – Sean Allred Nov 12 '14 at 15:34

    Just a guess: Is your shell trying to set the xterm window title? – Constantine Nov 12 '14 at 16:31
  • @Constantine That's exactly what it's doing. I've removed the problem statement for now (alias precmd 'echo -n "\033]0;${USER}@${HOST}:${PWD}\007"'), but is there any way to get Emacs to ignore or override this? – Sean Allred Nov 12 '14 at 16:43
  • I'm tempted to make a new question along the lines of "use a different shell rc file for emacs" and dupe this to that; it seems like the general case might be more useful for search engines. – Sean Allred Nov 12 '14 at 16:47
  • When writing this answer I discovered comint-preoutput-filter-functions. See C-h v comint-preoutput-filter-functions. You should be able to write a filter that removes the cruft before it gets inserted into a shell-mode buffer. term-mode is not based on comint, though. – Constantine Dec 11 '14 at 19:35

You might want to look at this question. Basically you need to avoid creating aliases for commands or prompts that assume that every shell is running where there is a window title to be set. Or create functions that do things differently depending on what kind of terminal they find themselves in.

As part of my bash initialization I do something like:

case "$TERM" in
    (emacs)
        # Emacs shell differences ...
        ;;
    (xterm*|dtterm*|linux|screen)
        # Embed working directory in window title
        PROMPT_COMMAND='echo -ne "\033]0;${SSH_TTY:+${HOSTNAME%%.*}:}${PWD##*/}\007"'
        ;;
    *)
        # Unrecognized terminal types get nothing
        ;;
esac

You need tcsh's precmd to do something equivalent.
