I'd like the title of my terminal windows to show the last command that ran. It'd be handy for finding the terminal that's running Mongrel in Dev/Test/Prod etc (for testing rails apps).
I tried this code:
if [ "$SHELL" = '/bin/bash' ] then case $TERM in rxvt|*term) set -o functrace trap 'echo -ne "\e]0;$BASH_COMMAND\007"' DEBUG # export PS1="\e]0;$TERM\007$PS1" ;; esac fi
At least, I think that's the code that I tried. It did work, but it caused some strange behavior, like window titles that would get stuck in a loop until I hit Ctrl C when changing directory to a symlink.
What's a reliable way to set my window title to the last command that was run?
