呼叫歷史/刪除命令時 Bash 提示命令被覆蓋

當刪除其後的文字或在歷史記錄中走得太遠時，我的 Bash 提示符號會自行清除。

登入時，提示看起來很正常。彩色用戶名周圍有白色括號，然後是白色 > 作為我的提示，但是如果我在歷史記錄中向上移動兩次，歷史命令將覆蓋我的提示：

[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

當我刪除命令時也會發生這種情況：

[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 中可能影響此問題的行是：

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，我想出了一個解決方案：

PROMPT_COMMAND=prompt

更改為：

PROMPT_COMMAND='PS1=`prompt`'

編輯：顏色被包裹在\[ \]（即color='\[\e[0;32m\]'）
