As of late, and without my deliberately doing anything to make it happen, my Bash prompt has an at sign (i.e. @) prepended to it. This did not previously happen. Nor can I see anything in my ~/.bashrc that seems as though it ought to be making this happen.

This is on Debian Jessie GNU/Linux, using GNU Bash.

For example, my current Bash sessions look like this:

@sampablokuper@debianbox:~$ python3 Python 3.4.2 (default, Oct 8 2014, 13:14:40) [GCC 4.9.1] on linux Type "help", "copyright", "credits" or "license" for more information. @>>> 1+2 3 @>>> exit() @sampablokuper@debianbox:~$ 

whereas originally, they would have looked like this:

sampablokuper@debianbox:~$ python3 Python 3.4.2 (default, Oct 8 2014, 13:14:40) [GCC 4.9.1] on linux Type "help", "copyright", "credits" or "license" for more information. >>> 1+2 3 >>> exit() sampablokuper@debianbox:~$ 

Here are all the lines from my ~/.bashrc that appear to in any way relate to the Bash prompt:

# set variable identifying the chroot you work in (used in the prompt below) if [ -z "${debian_chroot:-}" ] && [ -r /etc/debian_chroot ]; then debian_chroot=$(cat /etc/debian_chroot) fi # set a fancy prompt (non-color, unless we know we "want" color) case "$TERM" in xterm-color) color_prompt=yes;; esac # uncomment for a colored prompt, if the terminal has the capability; turned # off by default to not distract the user: the focus in a terminal window # should be on the output of commands, not on the prompt #force_color_prompt=yes if [ -n "$force_color_prompt" ]; then if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then # We have color support; assume it's compliant with Ecma-48 # (ISO/IEC-6429). (Lack of such support is extremely rare, and such # a case would tend to support setf rather than setaf.) color_prompt=yes else color_prompt= fi fi if [ "$color_prompt" = yes ]; then PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' else PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ ' fi unset color_prompt force_color_prompt # If this is an xterm set the title to user@host:dir case "$TERM" in xterm*|rxvt*) PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1" ;; *) ;; esac 

How can I get my Bash prompt to appear as it did originally?

Based on a meta discussion, I'm copying @steeldriver's perfectly good AU answer here:


You appear to have configured readline to enable edit mode indication. From 8.3.1 Readline Init File Syntax of the Bash Reference Manual:

show-mode-in-prompt (Off) If set to On, add a character to the beginning of the prompt indicating the editing mode: emacs (@), vi command (:) or vi insertion (+). 

You should be able to disable it in the current shell using

bind 'set show-mode-in-prompt off' 

To disable it persistently, you will need to find where it is getting set, possibly your ~/.inputrc or /etc/inputrc files.
