在 bash 中的自定义命令历史记录文件中循环进行反向搜索

我在文件中添加了一行~/.bashrc，它将所有发出的命令~/.bash_eternal_history以某种date directory history-number command格式附加到文件中，例如：

 2019-01-08.23:59:32    /home/sport/Desktop   745  pwd

我需要一个reverse-i-search功能来从自定义历史文件中调出命令来搜索关键字，并使用或键~/.bash_eternal_history逐个循环浏览每个结果updown

我怎样才能做到这一点？

这个，来自man bash：

   HISTFILE
          The name of the file in which command history is saved (see HISTORY below).  The default  value  is
          ~/.bash_history.  If unset, the command history is not saved when a shell exits.
   HISTFILESIZE
          The maximum number of lines contained in the history file.  When this variable is assigned a value,
          the history file is truncated, if necessary, to contain no more than that number of lines by remov‐
          ing  the  oldest  entries.  The history file is also truncated to this size after writing it when a
          shell exits.  If the value is 0, the history file is truncated to zero  size.   Non-numeric  values
          and  numeric  values  less  than  zero inhibit truncation.  The shell sets the default value to the
          value of HISTSIZE after reading any startup files.
