Sounds like a 'security' question, not a 'how to'
I think you need to deploy the 'alias' command here, replacing 'history' command by something else, that will lead to a bogus file.

This is just a point of view, you're welcome to differ.

Good luck

devel::repl::plugin::readlinehistory

Devel::REPL::Plugin::ReadLineHistory(3pm)		User Contributed Perl Documentation		 Devel::REPL::Plugin::ReadLineHistory(3pm)

NAME

       Devel::REPL::Plugin::ReadLineHistory - Integrate history with the facilities provided by Term::ReadLine

DESCRIPTION

       This plugin enables loading and saving command line history from a file as well has history expansion of previous commands using the
       !-syntax a la bash.

       By default, history expansion is enabled with this plugin when using Term::ReadLine::Gnu. That means that "loose" '!' characters will be
       treated as history events which may not be what you wish.

       To avoid this, you need to quote the '!' with '':

	 my $var = "foo!";

       or place the arguments in single quotes---but enable the "Term::ReadLine" attribute "history_quotes_inhibit_expansion":

	 $_REPL->term->Attribs->{history_quotes_inhibit_expansion} = 1;
	 my $var = 'foo!';

       and to disable history expansion from GNU readline/history do

	 $_REPL->term->Attribs->{do_expand} = 0;

CONFLICTS

       Note that Term::ReadLine::Perl does not support a history expansion method.  In that case, you may wish to use the Devel::REPL History
       plugin which provides similar functions.  Work is underway to make use of either History or ReadLineHistory consistent for expansion with
       either the Term::ReadLine::Gnu support or Term::ReadLine::Perl.
