Does OhMyBash change/flush my .bash_history by default?

[mehdiMj-ir]

I look at lib/history.sh file and it doesn't remove my history file aka .bash_history, even I add

export HISTSIZE=-1;
export HISTFILESIZE=-1

before source "$OSH"/oh-my-bash.sh to insure my history is limitless.
what should I do?

Does OhMyBash change/flush my .bash_history by default?

No. By default, Oh My Bash configures the unlimited history size by setting empty strings to HISTSIZE and HISTFILESIZE.

what should I do?

What would you like to achieve?

• If you don't want to flush ~/.bash_history, you don't have to do anything. Oh My Bash sets empty strings to HISTSIZE and HISTFILESIZE so the history will not be truncated.
  Or, even if you don't touch HISTSIZE and HISTFILESIZE at all, is your ~/.bash_history truncated? In such a case, what is the result of the command declare -p HISTSIZE HISTFILESIZE in an interactive session?
• If you want to truncate ~/.bash_history, you need to set HISTSIZE and HISTFILESIZE to the non-negative integer value (that represents the maximum number of history entries you want to keep) after source "$OSH"/oh-my-bash.sh. If you just want to clear everything, you need to set 0 to both the shell variables.
