“bash --noprofile --norc” 会破坏 .bash_history

Question

虽然我有HISTFILESIZE超过HISTSIZE500 个，但进入“norc”shell 后，bash 历史记录会被破坏。我该如何在各种 shell 类型中保留历史记录数据？

这是一个实际的例子。

// on the normal shell (bash)
/mnt/c/pg$ wc ~/.bash_history
  876  1997 19855 /home/user/.bash_history

/mnt/c/pg$ logout

PS > bash --noprofile --norc

// on the norc shell
bash-4.4$ wc ~/.bash_history
  847  1947 19406 /home/user/.bash_history
// -> notice that .bash_history is trimmed to the default 500 lines. This is the problem.

bash-4.4$ exit

// again on the normal shell
PS > bash

/mnt/c/pg$ wc ~/.bash_history
  848  1948 19439 /home/user/.bash_history
// -> once I enter to a norc shell, it affects the entire shell experiences

这是我的 .bashrc 和 .profile 的一部分

// .bashrc

export HISTCONTROL=ignoredups:erasedups  # no duplicate entries
export HISTSIZE=100000                   # big big history
export HISTFILESIZE=100000               # big big history
shopt -s histappend                      # append to history, don't overwrite it

// .. 

// .profile

export HISTCONTROL=ignoredups:erasedups  # no duplicate entries
export HISTSIZE=100000                   # big big history
export HISTFILESIZE=100000               # big big history
shopt -s histappend                      # append to history, don't overwrite it

// ..

使用空来运行它HISTFILE，因此 shell 不会尝试更新默认文件：

HISTFILE= bash --noprofile --norc
