Failure to Complete

[phikal]

Hi, I was trying to complete a directory path ~/Doc to ~/Documents using M-x shell, but instead I got this error message:

commandline: <<EOF
__emacs_complete_pre_command; function __emacs_complete_pre_command {  if [[ -z "$__emacs_complete_ps1" ]]; then    __emacs_complete_ps1="$PS1";    __emacs_complete_pc="$PROMPT_COMMAND";  fi;  PROMPT_COMMAND=__emacs_complete_prompt;  if [[ ${BASH_VERSINFO[0]} -eq 5 && ${BASH_VERSINFO[1]} -ge 1 || ${BASH_VERSINFO[0]} -gt 5 ]]; then  history -d $HISTCMD &>/dev/null || true;else  history -d $((HISTCMD - 1)) &>/dev/null || true;fi;} &&function __emacs_complete_prompt {  PS1='    $?';  PROMPT_COMMAND=__emacs_complete_recover_prompt;} &&function __emacs_complete_recover_prompt {  local r=$?;  PS1="${__emacs_complete_ps1}";  PROMPT_COMMAND="${__emacs_complete_pc}";  unset __emacs_complete_ps1 __emacs_complete_pc;  if [[ -n "$PROMPT_COMMAND" ]]; then    (exit $r); eval "$PROMPT_COMMAND";  fi;} &&__emacs_complete_pre_command

I have had a similar issue from time to time, but haven't been able to identify what the root cause is. Does the above give any hints? My Bash version is

I have similar issue when I connect through TRAMP. I have a customized prompt.

My prompt is just a dollar sign, and this occurs locally. That being said, I do notice that the issue appears to disappear when I rename my .bashrc to something else, which Bash won't load.

After experimenting a bit, I pulled out this block from by .bashrc:

if [ -f /etc/bashrc ]
then
    . /etc/bashrc
fi

and added that to my .bash_profile. This had the same effect as disabling .bashrc, but now my regular terminal didn't do any completion. This could be fixed by enabling the "Run command as login shell" option, in GNOME terminal.
