调用历史记录/删除命令时，Bash 提示命令被覆盖

当删除其后的文本或在历史记录中走得太远时，我的 Bash 提示会自动清除。

登录时，提示看起来很正常。彩色用户名周围有白色括号，然后是白色 > 作为我的提示，但是，如果我在历史记录中向上移动两次，历史记录命令会覆盖我的提示：

[stonewareslord] >        #Initial prompt. stonewareslord is green
                   | Cursor is above this pipe symbol

[stonewareslord] > ls     #Up arrow pressed once. ls was my last command. Colors are normal, ls is white
                     | Cursor is above this pipe symbol

pwdonewareslord] > ls     #Up arrow a second time. pwd overwrite [st. pwd is white and the other colors are normal. 
   | Cursor is above this pipe symbol

当我删除命令时也会发生这种情况：

[stonewareslord] > ls     #Typed command after initial prompt. stonewareslord is green
                     | Cursor is above this pipe symbol

[stonewareslord] > l      #Deleted one character
                    | Cursor is above this pipe symbol

                          #Deleted second character (line is blank). Anything I type is white
| Cursor is above this pipe symbol

bashrc 中可能影响此情况的行是：

color='\e[0;32m'  #Green
reset='\e[0m'     #Color is set back to normal (white)
prompt(){
    printf "[$color%s$reset]>" `whoami`
}
PS1=""
PROMPT_COMMAND=prompt

export HISTFILESIZE=
export HISTSIZE=
export HISTTIMEFORMAT="%Y-%m-%d_%H:%M:%S "
export HISTFILE=~/.bash_eternal_history

readonly HOME
readonly HISTIGNORE

好吧，我想出了一个解决方法：

PROMPT_COMMAND=prompt

更改为：

PROMPT_COMMAND='PS1=`prompt`'

编辑：并且颜色被包裹在\[ \]（即color='\[\e[0;32m\]'）中
